background and purpose: cutaneous infections arise from a homogeneous group of keratinophilic fungi, known as dermatophytes. since these pathogenic dermatophytes are eukaryotes in nature, use of chemical antifungal agents for treatment may affect the host tissue cells. in this study, we aimed to evaluate the antifungal activity of actinomyces species against trichophyton mentagrophytes (abbrevi...

It is concluded from experiments with (S)-[C015NH2]glutamine and [15N]ammonium sulphate that the biosynthesis of iodinin (1), in Brevibacterium iodinum, and of phenazine-1-carboxylic acid (7), in Pseudomonas aureofaciens, is primarily from a single nitrogen source (glutamine) and that the phenazines are constituted by combination of two units of the same precursor, as 5. Some observations are m...

Thirteen species of Streptomycetes, Arthrobacters and Mycobacterium were studied for the determination of a potential cholesterol oxidase producer. Only Streptomyces fradiae and Streptomyces rishiriences were found to be capable of producing this enzyme. Streptomyces fradiae was selected for the production of cholesterol oxidase and cultured in different media to find optimum media and con...

background and objectives: in marine actinomycetes, carotenoid production occurs in constitutive, light-dependent or cryptic manner. the present work deals with the fermentative production of carotenoids from marine actinomycetes. materials and methods: marine actinomycetes namely streptomyces strain aqbmm35 was isolated from the marine sponge mycale mytilorum collected from south west coast of...

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...
