conclusions the crude extract of streptomyces sp. acs52 had high antibacterial activity against a wide spectrum of bacteria and could be of interest due to its features such as ability to grow at low temperatures and alkaline ph levels. results streptomyces sp. acs52 is a cold-resistant alkalophilic bacterium strain with antibacterial activity against a broad spectrum of pathogenic bacteria. th...

blastocystis hominis is a protozoan parasite which mainly found in human fecal samples both from symptomatic patients and asymptomatic population in developing countries. in this study we reported a patient referred to gi clinic with abdominal pain, nausea, vomiting, fever for 2 or 3 days and passed watery stools because of blastocystis sp. subtype 2 infection.

the aim of this study was to find the optimal conditions of a newly isolated streptomyces strain jrs 19. screening for keratinase producing bacteria and their keratinase production were investigated. the keratinase produced by the isolate was purified by chromatographic techniques and the optimum ph maintained was 7.0 and maintained at different temperatures viz., 20ºc, 25ºc, 30ºc, 35ºc and 40º...
