Mamun ankmamun@yahoo.com <p>Biosorption can be defined as a Physiochemical process that cleanses heavy metal-contaminated water and aids in environmental remediation. The present exploration was carried out to examine the metal biosorbent potentiality of five bacterial strains.Biosorption capacity was assessed using Atomic Absorption Spectrophotometer where <em>Bacillus thuringiensis</em> showed uptake of Pb 0.56mg/g that was around 34.74%, Cd 0.38mg/g (20.0%), Ni 0.30 mg/g (15.8%), Cr 0.76mg/g (39.58%), Cu 0.14mg/g (7.61%) and As 0.28mg/g (14.43%) respectively. <em>Micrococcus sp.</em> showed reduction of Pb 0.62mg/g (39.89%), Cd 0.40mg/g (21.10%), Ni 0.22mg/g (11.6%), Cr 0.46mg/g (23.96%), Cu 0.56mg/g (30.43%) and As 0.03mg/g (1.75%) respectively whereas <em>Pseudomonas sp. </em>exhibited reduction of As 0.56mg/g and 0.20mg/g (16% and 10%), Cu 0.26mg/g and 0.46mg/g (14% and 25%), Cr 0.74mg/g and0.56mg/g (39% and 29%), Ni 0.12mg/g and 0.38mg/g (6% and 20%), Pb 0.26mg/g and 0.68mg/g (19% and 41%) and Cd 0.46mg/g and 0.64mg/g (24% and 34%) respectively. The result displayed that the highest degradation of Pb and Cr were shown by <em>Pseudomonas aeruginosa </em>(41±0.01%) and <em>Bacillus thuringiensis </em>(39.58±0.05%) and lowest degradation of As was shown by <em>Micrococcus sp.</em> that was around 1.75±0.001%. By contrast, degradation of Pb in moderate condition was witnessed by <em>Bacillus cereus </em>(19.89±0.01%) and Ni by <em>Bacillus thuringiensis </em>(15.8±0.05%) respectively. Heavy metal’s biosorption is a quick process that might be an advantageous side for the removal of vast range of pollutants.</p> 2022-05-04T00:00:00+02:00 Copyright (c) 2022 MD MONIRUL ISLAM, Liakat Hossain, Monirul Islam, Pronabananda Das, S.A.M.

Hence this study was aimed at accessing the bacteriological quality and physicochemical parameters of well waters located in Emene-Enugu, Nigeria. Water samples were aseptically drawn from ten different wells in Emene-Enugu. Physicochemical parameters such as temperature, pH, turbidity and electrical conductivity were determined using standard methods. Total and fecal coliform counts were also determined using the membrane filtration method. The isolates were also identified using cultural and biochemical tests. Pearson’s correlation was used to determine the relationship between the parameters. Temperature of the well waters ranged from 31.5±0.11 to 33.7±0.11<sup>o</sup>C while the pH ranged from 6.20±0.01 to 7.40±0.01. Turbidity and conductivity also ranged from 25±0.05 to 150±0.06 NTU and 21±0.58 to 163±0.12µS/cm respectively. Total and fecal coliform counts ranged from 0 to 179±2.31 cfu/100ml and 0 to 58±0.58 cfu/100ml respectively. Bacteria identification revealed the presence of <em>Enterobacter aerogenes</em>, <em>Salmonella enterica</em>, <em>Enterococcus faecalis</em>, <em>Proteus vulgaris</em>, <em>Escherichia coli</em>, <em>Klebsiella pneumonia</em> and <em>Citrobacter freundii</em>, in the water samples. Turbidity was significantly correlated with temperature, pH and fecal coliform (p = 0.000; r = 0.693, p = 0.000; r = -0.679 and p = 0.000; r = -0.655) respectively. These isolates are potential human pathogens, thus the well waters used in this study are not fit for human consumption and should be properly treated and monitored before domestic use.</p> 2022-05-24T00:00:00+02:00 Copyright (c) 2022 Augustine Mbachu, Chisom Ani, Nancy Mbachu https://office.scicell.org/index.php/BE/article/view/335 Hawthorn HAWTHORN, A PROMISING PLANT WITH DIVERSE BIOMEDICAL APPLICATIONS 2021-12-15T15:10:27+01:00 Jamila Ramadan jamilakhalilramadan@gmail.com Mahmoud Khalil jkr146@student.bau.edu.lb <p>Hawthorn (<em>Crataegus</em> species) is distributed widely in Asia, North America and Europe.

Nanobacteria are the name of a proposed class of living organisms particularly cell-walled microorganisms with a size much smaller than the generally accepted lower limit size for life (about 200nm). Recently, histopathological immunohistochemical staining, transmission electron microscopy (TEM), and calcific staining studies revealed the association of nanobacteria in kidney and gall stones. Nanobacteria have been appeared to contribute to different benign and malignant calcifications in the form of calcium phosphate crystals and contribute to malignant calcifications in breast and ovarian cancer. Nanobacteria also cause prostatic stones in patients with chronic pelvic pain syndrome due to chronic prostatitis and are present in dental and pulp calculus. The evidence that nanobacteria exist within the human body and are closely related to numerous sorts of diseases is now overpowering. However, future research is required to reveal their nature and impact on health and disease. This paper aimed to highlight the harmful role of nano-bacteria on human health and to describe the association of nanobacteria and their hypothesized relationship with some human diseases.</p> 2022-05-24T00:00:00+02:00 Copyright (c) 2022 Ali Mohamed Elshafei https://office.scicell.org/index.php/BE/article/view/329 THE IMPORTANCE OF BIO FERTILIZERS AS ALTERNATIVE SOIL FERTILITY AMENDMENTS 2021-10-01T09:26:42+02:00 Chrispo Makheti Mutebi cmutebi@yahoo.com Vincent Moranga cmutebi@yahoo.com <p>There is a current interest in agrarian sustainability with soil microorganisms instead of agro-chemicals. Key constraints in the use of bio fertilizers are; inadequate awareness about bio inoculants and lack of promotion network and publicity among the end users. This review discusses current technical information a way of creating awareness in order to promote the use of bio fertilizers. Publon, Google Scholar, Science Direct and Microsoft Academic data bases were used for the review 2021. Research and review articles published from 2019 onwards were considered as current information for the review. The findings of the review are that; both primary and secondary macronutrients can be provided by bio fertilizers. Potential microbes are; free-living nitrogen fixing bacteria and cyanobacteria, symbiotic nitrogen-fixing bacteria and fungi such as mycorrhiza. Other important functions of bacteria are; conferring to plants the ability for salt tolerance, lignin degradation and remediation of heavy metals from the soil. Bio Compost, vermicompost and termite soil with their rich microorganism content can be used as bio fertilizers for soil nutrient increase. In order to reap maximum benefit from bio fertilizers there is need to formulate them in appropriate materials. Apart from addition of nutrients to the soil, bio fertilizers play an important role in plant health, conclusion. This paper has brought to the fore the need to improve rhizosphere management in a sustainable way particularly at this point in time when there are strong indications that it has deteriorated in the face of continued use of chemical fertilizers.</p> 2022-05-04T00:00:00+02:00 Copyright (c) 2022 Chrispo Makheti Mutebi, Vincent Moranga https://office.scicell.org/index.php/BE/article/view/383 ANTIBACTERIAL EFFICACY OF Anopheles gambiae (MOSQUITOES) EXTRACTS ON SOME BACTERIA CAUSING THROAT INFECTIONS 2021-11-17T12:52:46+01:00 Lateef Kasim checksyr@gmail.com Muftau Kolawole Oladunmoye Checksyr@gmail.com <p><strong>Introduction: </strong>Respiratory tract infection refers to any infectious disease involving the respiratory tract. In low-income and middle-income countries, respiratory tract infection is considered as one of the major public health problems. It can lead to severe mortality and morbidity in children as well as adults. Over the years there has been a development of resistance to antibiotics used for the treatment of throat infections which has led to the search for alternative therapy. Insects can be potentially useful as an alternative therapy because of the diverse bioactive compounds they possess.</p> <p><strong>Objective: </strong>This research investigated the antibacterial activity of the extract of <em>Anopheles gambiae</em> against bacterial isolates associated with throat infection.</p> <p><strong>Methods</strong>: The insects were bred in microbiology laboratory and identified in the Department of Biology, Federal University of Technology, Akure. The mosquitoes were collect and immobilized in the freezer at -4<sup>o</sup>C. The extracts were prepared by mecrating the mosquitoes into 30% Dimethlsulfoxide (DMSO) for its homogenization. Extracts were then tested against bacterial isolates <em>in-vitro </em>using agar well diffusion method. <strong>Results: </strong>Extracts were tested against bacterial isolates using agar well diffusion method which showed activity against <em>S. pyogenes</em> (22.00 ± 0.58<sup>b </sup>mm), <em>S. aureus</em> (19.67 ± 1.20mm) and <em>K. pneumoniae</em> (24 ± 1.15mm), while it showed no activity against <em>E. coli</em> and <em>S. pneumoniae</em>. <strong>Conclusion</strong>: <em>A. gambiae</em> extract may be considered as an alternative in medicine to combat the issue of increasing multidrug resistance to conventional antibiotics, the side effects of these antibiotics and high cost of synthetic drugs production. The most prevalent compound was n-hexadecenoic with retention time of 20.997, which was reported to exhibit antioxidant and antimicrobial activity.</p> 2022-05-04T00:00:00+02:00 Copyright (c) 2022 Lateef Kasim, Muftau Kolawole Oladunmoye https://office.scicell.org/index.php/BE/article/view/354 GROWTH EVALUATION OF SULPHATE-REDUCING BACTERIA (SRB) ASSOCIATED WITH BURIED MILD STEEL RODS 2021-10-25T11:47:22+02:00 Ifeoluwaposi Oluwabunmi Ogundana ogundana.ifeoluwaposi@gmail.com Adewale Oluwasogo Olalemi waleolas2002@yahoo.com Daniel Juwon Arotupin djarotupin@futa.edu.ng <p><strong>Introduction: </strong>Sulphate-reducing bacteria are the major cause of corrosion of underground structure corrosion of underground structures made of mild steel.</p> <p><strong>Objective: </strong>This study set out to evaluate the growth pattern of sulphate-reducing bacteria associated with buried mild steel rods in Akure metropolis, Nigeria</p> <p><strong>Methodology: </strong>Mild steel rods (12 mm diameter, area 39.97 cm<sup>2</sup>), were collected from Ondo State Water Corporation (ODSWC), Akure, Nigeria and were buried and monitored for a period of three months.

The availability of new antibacterial agents appeared to be a very complex process. One of the most important aspect of modern field research is nanotechnology, it deals with synthesis, design and manipulation of particles structures ranging from approximately 1-100nm. Nanoparticles (NPs) are of great importance in areas like health care, cosmetics, food and feed, environmental health e.t.c. Nanoparticles matrix properties and constituent materials can be used to categorized them into inorganic and organic nanosystems. Techniques use within the synthesis of NPs includes; chemical, physical, chemistry, and biological methods, every methodology has its advantages and disadvantages with common issues of value, quantifiability and uniform particle size. Famous microbiologist Alexander Fleming said that “There is probably no chemotherapeutic drug to which in suitable circumstances the bacteria can not react by in some way acquiring fastness.” thus, there's high chance that the organism can also become resistance to newly developed medication at later stage. To this end NPs are considered to be good antibacterial agents and may overcome the barrier of MDR owing to their ability to anchor to the bacterial cell wall, multifunctional mechanisms to intervene normal cell functionality and subsequently penetrate it, thereby causing structural changes in the cell membrane permeability leading to cell death.</p> 2022-05-24T00:00:00+02:00 Copyright (c) 2022 Tope Abraham Ibisanmi, Jamiu Olaseni Aribisala https://office.scicell.org/index.php/BE/article/view/334 ANTIBACTERIAL AND ANTIFUNGAL ACTIVITIES OF Impatiens balsamina (L.): LITERATURE REVIEW ARTICLE 2021-10-25T11:48:21+02:00 Anggun Hari Kusumawati anggunhari@ubpkarawang.ac.id Siti kholillah anggunhari@ubpkarawang.ac.id Farhamzah Mr. anggunhari@ubpkarawang.ac.id Amad Samsudin anggunhari@ubpkarawang.ac.id Sukma Dewi Apriana anggunhari@ubpkarawang.ac.id Anggi Maudia Permadi anggunhari@ubpkarawang.ac.id Irma Adawiah anggunhari@ubpkarawang.ac.id Hasnimar Mr. anggunhari@ubpkarawang.ac.id <p>The human body contains a diverse range of microorganisms, including bacteria and fungi. The most common bacteria and fungi caused skin pathogens are Staphylococcus aureus, Propionibacterium acnes, Staphylococcus epidermis and Candida albicans. Many studies have found that <em>Impatiens balsamina</em> (L.) contains antibacterial and antifungal activities. Acne and Candidiasis are diseases that often arise and can interfere with comfort for sufferers. Usually, acne is caused by the bacteria Propionibacterium acnes, Staphylococcus epidermis and Staphylococcus aureus, and Candidiasis caused by the Candida albicans. One of the plants that is widely used as an antiacne and antifungal treatment is the <em>Impatiens balsamina</em> (L.). <em>Impatiens balsamina</em> (L.) has antiacne and antifungal activities. The purpose of the review is to find out if the <em>Impatiens balsamina</em> (L.) has activity as an antiacne, antifungal and can identify secondary metabolites that can inhibit the emergence of bacteria in acne and candidiasis in various journals. The method used is the Literature Review Article (LRA) method. A search through Google Scholar and Pubmed found 12 articles that <em>Impatiens balsamina</em> (L.) contains secondary metabolites, namely flavonoids and saponins. The mechanism of action of flavonoids is by inhibiting the function of cell membranes and energy metabolism of bacteria, while the mechanism of action of saponins as antifungals is by damaging cell membranes, causing cell leakage which ultimately leads to cell death. From the two mechanisms, these secondary metabolites can have antiacne and antifungal activities.</p> 2022-05-04T00:00:00+02:00 Copyright (c) 2022 Anggun Hari Kusumawati, Siti kholillah, Farhamzah Mr., Amad Samsudin, Sukma Dewi Apriana, Anggi Maudia Permadi, Irma Adawiah, Hasnimar Mr. https://office.scicell.org/index.php/BE/article/view/384 PRODUCTION AND UTILIZATION OF PULLULANASE FROM BACILLUS CLAUSII FOR ENHANCED RESISTANT STARCH PRODUCTION IN GARRI 2021-12-15T15:19:37+01:00 Nwanneka Nwozor nc.nwozor@unizik.edu.ng Frank Ogbo fc.ogbo@unizik.edu.ng <p>Resistant starch is the portion of starch which escapes digestion in the small intestine and passes into the large intestine where it is fermented by gut microflora. It is considered a functional component of food due to the health benefits it confers following its consumption. The aim of this research was to produce garri with high resistant starch using pullulanase enzyme from <em>Bacillus clausii</em>. The organism was isolated from different cassava processing sites in Awka and identified based on phenotypic, biochemical and molecular characteristics. Pullulanase assay was carried out using standard procedures at 540 nm. Optimum conditions for pullulanase production was determined, after which the pullulalanse enzyme was used to modify garri. The test organism with the highest pullulanase activity was identified as <em>Bacillus clausii</em>. Optimum pullulalanse activity was observed with an innoculum size of 3.0ml, pH 6, an incubation temperature of 35<sup>o </sup>C and incubation time of 48 hours. The resistant starch content was found to be higher for enzyme-treated garri samples (13.81%) than for the untreated garri samples with (2.69%). This research shows that pullulanase enzyme from <em>Bacillus clausii</em> is a very useful industrial raw material for the increased production of resistant starch in foods.</p> 2022-05-04T00:00:00+02:00 Copyright (c) 2022 Nwanneka Nwozor, Frank Ogbo
