Research ArticleOpen accessIn the keywordsScreening of Yeast Strains for Pectinolytic Activity: Effects of Different Carbon and Nitrogen Sources in Submerged FermentationsMustafa Oskay, Hüsniye Tansel YalçinTwenty yeast strains were screened for pectinolytic activity, among the strains, only nine were positive for pectinase production. The best strain was Kluyveromyces marxianus NRRL-Y-1109 which gave high quantities of pectinase activity, by submerged fermentation. Different parameters such as incubation time, pH (3.5-7), temperature (20-45°C), nitrogen and carbon source, were optimized. The optimal incubation time, temperature and pH for pectinase … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 22 Jun 2015 · 7,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Overview of the Antimicrobial Activity of Some Microbial EnzymesAkram N. Salah, Hayam Atallah AlwabsiEnzymes are substances produced by living organisms that are used to catalyze some biological and biochemical reactions as they either catalyze some types of polysaccharides and proteins or lyse complex materials such as polymers and lipids. Microbial enzymes are defined as the enzymes that can be extracted and purified from bacterial strains such as Bacillus spp., Pseudomonas spp., Streptomyces, or … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 11 Jun 2024 · 6,081 accessesView PDFCite
