Evaluation of the microbiological quality of the environment in a laboratory of microbiology candidate to the accreditation
The microbiological quality of the environment of two laboratories of microbiological quality control of the agro alimentary products, the first candidate to the accreditation and the second not candidate to the accreditation was evaluated. The samples of air were taken by aspiring the air, through physiological water of a biocollector, rooms of laboratories to a flow of 2L/min. The test sample selection of surfaces was carried out by cleaning. Vol. 4 | No. 4 | 2015 Full Text

Evaluation of antifungal, hemolytic and cytotoxic potentiality of ethyl acetate crude extracts of a novel marine Streptomyces spp. AIAH-10
To face newly generated diseases, searching for new, safe and effective bioactive molecules is urgent and marine microbial flora may be a potential source. The present study was designed to isolate marine microorganisms (AIAH-1 to AIAH-29) from the soil of mangrove forest Sundarbans, Bangladesh by serial dilution method using isolation media. Among them, AIAH-10 was selected for further study due to its promising antibacterial activity (done by streak plate and plug technique method) against a series of pathogenic bacteria. On the basis of morphological, cultural and biochemical analysis, the strain AIAH-10 belongs to Streptomyces spp. Secondary metabolites of the strain was obtained by small scale fermentation process.
