Variation of Surface Properties of Streptomyces griseus Cells after Heat Treatment with Liposome
نویسندگان
چکیده
Surface properties of Streptomyces griseus cells, such as surface net charge and surface net hydrophobicity, were characterized by using the aqueous two-phase system (ATPS) method. It was found that the surface net charge of S. griseus cells was reduced after the POPC liposome-treatment of the cells at 41C. The surface net hydrophobicities of S. griseus cells and liposome-treated cells cultivated at 41C were about -122 and -510 kJ/mol, respectively, evaluated by the ATPS method. The above results show that the variation of the cell surface properties could be obtained by the cell-liposome interaction under heat stress conditions.

Oxidation of Meloxicam by Streptomyces griseus
The aim of the present investigation was to biotransform the anti-inflammatory compound meloxicam by enzymes present in whole cells of five actinomycete cultures to produce novel bioactive derivatives. Among the actinomycetes screened, Streptomyces griseus NCIM 2622 was found to possess the enzyme system(s) that oxidize meloxicam into two metabolites whereas that present in S. griseus NCIM 2623...
متن کاملThe purification and properties of two staphylolytic enzymes from Streptomyces griseus.
1. Two staphylolytic enzymes have been purified from cultures of a soil isolate of Streptomyces griseus. 2. The purified enzymes were shown to be basic proteins of low molecular weight. Each enzyme released N-acetylmuramic acid reducing groups from the cell walls of Staphylococcus aureus. 3. The enzymes lysed whole staphylococci best at higher pH values and lower ionic strengths than when the s...

Introduction: Streptomyces species are mycelial, aerobic gram-positive bacteria that are isolated from soil and produce a diverse range of antibiotics. Streptomyces griseus produces the antibiotic, streptomycin and forms spores even in a liquid culture. The gene cluster for the production of Streptomycin antibiotic contains strR gene that encodes StrR, a pathway-specific regulator. Then, this p...
متن کاملA Study of the Chemical Composition and Heat Treatment of Electroless Ni-B-Tl Alloy Coating on AISI 316 Stainless Steel
Despite having some useful properties, stainless steels suffer from lack of suitable surface hardness. In this research electroless Ni-B-Tl coating was used with the aim to increase their surface hardness. The effects of Nickel chloride, Sodium borohydride, Thallium nitrate and Ethylendiamin on the chemical composition of coating were studied. To achieve an increase in hardness, the effects of ...
