conclusions the streptomyces sp. suk 25 culturing was optimized using thronton media, at ph 7 and aeration of 140 rpm. further isolation and identification of bioactive compounds will develop anti-mrsa therapeutics. materials and methods disc diffusion and minimum inhibitory concentration (mic) assay were used to determine the antibacterial activity of streptomyces sp. isolates. optimization of...

production of oxytetracycline by an isolated strain of streptomyces rimosus from iranian soil was investigated using a special fermentation medium. a comparative study was performed with standard strain ptcc 1144 using the following parameters optimum growth conditions with respect to time, ph, and different amounts of corn steep liquor. surprisingly, the production yield of the wild strain was...

starch is a versatile and useful polymer having physicochemical properties that can be altered by chemicals or enzymatic modification and/or physical treatment. native starches possess many disadvantages that decrease their application and industrial use, but could be modified to obtain the desired properties to meet industrial needs for a wide range of starch applications. physically modified ...

We report the draft genome sequence of Streptomyces sp. M1013, a strain isolated from the Medicago arborea rhizosphere in Izmir, Turkey. An average nucleotide identity (ANI) analysis reveals that this strain belongs to the same species as Streptomyces canus ATCC12647 and is closely related to Streptomyces ambofaciens and Streptomyces coelicolor.

the potential of marine actinobacteria particularly streptomyces as a single cell protein (scp) feed for the growth of ornamental fish, xiphophorus helleri has been investigated. the streptomyces strains used as scp were isolated from the marine sponges, namely callyspongia diffusa , mycale mytilorum , tedania anhelans and dysidea fragilis . six scp feeds were prepared and their effects were co...

We report the draft genome of Streptomyces rimosus (ATCC 10970), a soil isolate that produces oxytetracycline, a commercially important and clinically useful antibiotic.

L-Phenylalanine and L-tyrosine were completely catabolized through homogentisate by Streptomyces setonii 75Vi2 but only partially degraded by Streptomyces badius 252, Streptomyces sioyaensis P5, Streptomyces viridosporus T7A, and Streptomyces sp. strain V7. Intermediates of catabolism were confirmed by thin-layer, gas, and high-pressure liquid chromatography. Homogentisate 1,2-dioxygenase was p...
