Kinetics of alkaline protease production by Streptomyces griseoflavus PTCC1130
BACKGROUND AND OBJECTIVES Proteases are a group of enzymes that catalyze the degradation of proteins resulting in the production of their amino acid constituents. They are the most important group of industrial enzymes which account for about 60% of total enzymes in the market and produced mainly by microorganisms. The attempts were made to study the kinetic parameters of protease produced by S...
متن کاملMetabolic products of microorganisms. 246. 2880-II, a metabolite related to ferulic acid from Streptomyces griseoflavus.
By chemical screening methods we detected in the mycelium of Streptomyces griseoflavus (strain Tii 2880) the colabomycin-complex2) and a second compound, called 2880-ll (Rf values see Table 1). 2880-ll absorbed UV light on Silica gel F254, and turned black with molybdatophosphoric acid and dark brown with vanillinsulfuric acid. It could be separated from the crude extracts by silica gel chromat...
متن کاملIn-vitro Differentiation of Human Umbilical Cord Wharton’s Jelly Mesenchymal Stem Cells to Insulin-Producing Cells
Background & Objective: Diabetes is a major chronic metabolic disease in the world. Islet transplantation is a way to treat diabetes. Unfortunately, this method is restricted due to graft rejection and lack of donor islets. Mesenchymal Stem Cells (MSCS) have the ability to differentiate into Insulin-Producing Cells (IPCs). In this study, Human Umbilical Mesenchymal Stem Cells (HUMSCS) were in...
متن کاملCombination of In Vivo Cryptorchid Testis and In Vitro Co- Culture System to Obtain High Purification and Proliferation of Mouse Spermatogonial Stem Cells
Background The present study was designed to evaluate the survival and proliferation of spermatogonial stem cells from cryptorchid mouse testis in co-culture system over a 3 weeks period. MaterialsAndMethods Sertoli and spermatogonial cells were isolated from bilateral cryptorchid mouse model testes. Isolated spermatogonial cells were co-cultured with Sertoli cells in minimal essential medium (...
متن کاملDesferrioxamine E produced by Streptomyces griseus stimulates growth and development of Streptomyces tanashiensis.
The authors previously reported that interspecific stimulatory events between Streptomyces species for antibiotic production and/or morphological differentiation mediated by putative diffusible metabolites take place at a high frequency. This paper reports the isolation and characterization of a substance produced by Streptomyces griseus that stimulates the growth and development of Streptomyce...
