PaulA moderately halophilic bacterium, Halomonas xianhensis SUR308 (Genbank Accession No. KJ933394) isolated from solar saltern of Surala, Odisha, India was found to produce significant amount of a biologically active extracellular polymeric substances (EPS). Under optimized cultural conditions, the strain was able to produce 7.05 g L-1 of EPS after 8 days of incubation under shake culture. To enhance the EPS … …Current Research in Microbiology, Vol. 7, Issue 1 · 1 Apr 2016 · 15,918 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnhanced Production of Extracellular Alkaline Lipase by an Improved Strain of Pseudomonas aeruginosa MTCC 10,055Deepali Bisht, Santosh Kumar Yadav, Nandan Singh DarmwalProblem statement: Lipases are industrially important enzymes having applications in numerous industries. For easy commercialization it is necessary to produce lipases at industrial level which could be achieved by strain improvement and medium formulation. Approach: In the present study strain improvement of Pseudomonas aeruginosa MTCC 10,055 was done by chemical mutagenesis using mutagen 4-nitroquinoline1-oxide for alkaline lipase production. Different fermentation … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 24 Nov 2011 · 8,760 accessesView PDFCite
Research ArticleOpen accessIn the keywordsProduction, Extraction and Characterization of Lipases from the Antarctic Yeast Guehomyces pullulansLuis Lascano-Demera, Patricia Portero Barahona, Enrique Javier Carvajal BarrigaThe production of extracellular lipases from the Antarctic yeast Guehomyces pullulans is induced using an olive oil medium as an inductor substrate and a first characterization of its enzyme, using the protein extract obtained from the medium, is described. For this, the effect of pH and temperature on the lipase activity are evaluated and the enzyme kinetic for the lipase … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 2 · 11 Apr 2019 · 10,020 accessesView PDFCite
Research ArticleOpen accessIn the abstractExpression and Induction Optimization of Mucor Circinelloides Lipase in Escherichia ColiYueping Yang, Yao Zhang et al.Microbial lipases serve as versatile biocatalysts for modifying lipid substrates, enabling diverse biotechnological applications spanning food technology, renewable energy production, and pharmaceutical sectors. Genomic analysis of Mucor circinelloides WJ11 revealed multiple lipase-encoding genes, with WJ_23 successfully cloned and heterologously expressed in Escherichia coli. Since the lipase expression was mainly concentrated in the cell pellets, appropriate induction strategies had been investigated … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 13 Jun 2025 · 5,982 accessesView PDFCite
Research ArticleOpen accessIn the abstractCross Talk between Iron Regulatory Proteins and Proinflammatory Molecules in Ovarian Cancer Patients Based on Menopausal StatusHaritha Padannapurath Manoj, Sudha Kuthethur, Reshma Kumarchandra et al.Micronutrient iron is postulated to contribute to the initiation of cancer mainly by the formation of Reactive Oxygen Species (ROS), the key signaling molecules of inflammatory reactions. Iron may also cause elevation of MMP9, a gelatinase responsible for remodeling extracellular matrix in cancer cells through the ROS pathway. Estrogen the hormone which decreases markedly in post menopause is also known … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 31 May 2024 · 4,491 accessesView PDFCite
