Research ArticleOpen accessIn the keywordsIdentification of Major Cultivable Aerobic Bacteria in the Oral Cavity of Malaysian SubjectsKoshy Philip, Wuen Yew Teoh, Sekaran Muniandy, Hashim YaakobCulture dependent and culture independent methods have shown that about 600 species of bacteria inhabit the human oral cavity. While some oral microorganisms have a direct link to dental caries, periodontal disease and halitosis, opportunistic pathogens may be responsible for systemic diseases such as bacterial endocarditis, aspiration pneumonia, osteomyelitis in children, preterm low birth weight, coronary heart disease and cerebral … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 7,990 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMicrobial Biodiversity Screening for Metal Accumulators from Mineral Ore Rich Site in Andhra Pradesh, IndiaAditya Kumar Sarkar, Susmita Roy, Ananya Pal et al.Problem statement: Since the site selected for screening was a source of magnetite, the objective of this study was to isolate some groups of magnetotactic bacteria and microbes with potential of metal accumulation. Approach: The culture based approach was used for the study. Pure isolates obtained were characterized on the basis of morphology, biochemical tests, physiology as well as at … …OnLine Journal of Biological Sciences, Vol. 8, Issue 2 · 30 Jun 2008 · 7,546 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNew Bacterial Species Isolated from Malaysian Sea Cucumbers with Optimized Secreted Antibacterial ActivityAbd El-Aziem Farouk, Faizal Abd. Hamid Ghouse, B.H. RidzwanIn this study, several Malaysian sea cucumber species that have traditional medicine value were selected and from them, the native bacterial population was isolated. Optimization of growth was designed and all bacterial secretions were tested for antibacterial properties. 30 bacterial types were isolated and 7 types recorded moderate antibacterial activity against K. pneumoniae, S. marscens, P. aeruginosa and E. feacalis. … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 8,841 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Identification of Bacteria Leading to Microbial Spoilage of Sweet Potato and Screening for Antistaling Agents Running HeadDaoqi Liu, Huili Liu, Yuanyuan Dang et al.To develop natural preservatives tailored for sweet potatoes, the control effect of essential oils on the spoilage microorganisms of sweet potatoes is uncertain. Therefore, we first isolated and identified the dominant spoilage bacteria from spoiled sweet potatoes. Micrococcus aloeverae, Priestia aryabhattai, and Glutamicibacter arilaitensis were identified through screening, morphological observation, gram staining, and 16S rDNA assays. Subsequently, five plant essential … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 26 Apr 2024 · 5,221 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarly Detection of Endobacteria in Rhizopus spp.Ratna Noviyanti, Gayuh Rahayu, Rida Oktorida KhastiniRhizopus spp. are commonly used in bio-industrial processes such as manufacturing traditional fermented foods. However, one species, R. microsporus has been reported to contain toxin-producing endobacteria. Therefore, it is essential to evaluate the Rhizopus strains' safety before application as tempe inoculum. The study aimed to detect the presence of endobacteria from seven strains of Rhizopus spp. isolated from Tempe and … …OnLine Journal of Biological Sciences, Vol. 23, Issue 3 · 24 Jun 2023 · 5,331 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Identification of a Bioflocculant-Producing Strain and Application in Rice Vinegar ClarificationWeilian Hu, Dehui DaiA bioflocculant-producing bacterium S-3# was isolated from fresh sand bones 40-50 cm underground in the desert region of China’s Ningxia Province. It was identified as Paenibacillus sp. based on 16S rDNA sequence along with its biochemical and morphological characteristics. Chemical analysis found that the bioflocculant from S-3# is mainly composed of extracellular polysaccharide. Researchers observed no noticeable change (above 91%) … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 30 Dec 2020 · 5,924 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhylogeny and Molecular Study of Some Entomopathogenic Rhizobacteria Isolated from Two Regions in AlgeriaOulebsir-Mohandkaci Hakima, Benzina Farida, Khemili-Talbi Souad et al.The use of bacteria in the control of insect pests is a form of biological control whose practice is still not widespread. It is in this context that the present work falls. It concerns the isolation, characterization and identification of local bacterial strains for the purpose of their use in the control of certain pests. Indeed, 20 bacteria were isolated … …Current Research in Bioinformatics, Vol. 8, Issue 1 · 2 Mar 2020 · 7,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Process Conditions for the Production of Holocellulase by a Bacillus Species Isolated from Nahoon Beach SedimentsEvelyn N. Fatokun, Uchechukwu U. Nwodo, Ademola O. Olaniran, Anthony I. OkohProduction of holocellulase by a newly isolated marine Bacillus species via submerged fermentation technique at varying cultivation conditions was investigated. Enzyme production was optimized by altering one variable per time. Moreover effect of lignocellulosic saccharides in inducing cellulase and xylanase production was also investigated. The 16S ribosomal Deoxyribonucleic Acid (16S rDNA) gene sequence analysis exhibited 98% sequence similarity of the … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 2 · 8 Apr 2017 · 8,029 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Identification of Staphylococcus epidermidis S14 Screening Extracellular Antimicrobial MetabolitesJie Zhang, Han Jiang, Jiaxin Jiang, Guangrong HuangTotal 24 isolates with antimicrobial activity against Staphylococcus aureus, Escherichia coli, Bacillus cereus and Shigella castellani, out of 259 strains, were isolated from the internal of seven marine fishes. The extracellular metabolites of strain S14, isolated from the internal of shark, showed stronger inhibition against the four tested bacteria, including G- and G+ bacteria.
