Doğal Pigment Adayı Streptomisetlerin Gelişimlerine Çevresel Faktörlerin Etkisi

Özet

The purpose of this study was the determination of candidate Streptomycetes to the natural pigment production, and to investigate the
effects of environmental factors on their growths. In the study used 15 Streptomyces genus as a source of organisms, and were determined
the spore morphologies, aerial and diffuse pigments and biochemical properties of all cultures. In the study was also investigated effects of
temperature, pH and agitation speed on the growths of Streptomyces. According to the study results, the 46% of cultures have grown
optimally at pH 7 and 54% of cultures have developed optimally at pH 8. As a result of the temperature experiments, the 33% of cultures
at 25°C, 20% of cultures at 30°C and 46% of cultures at 35°C have developed optimally. Optimal growth has not been found at 40°C.
When it was investigated effects of agitation speed, 93% of the cultures at 300 rpm have grown optimally, only 7% of the cultures have
developed optimally at 200 rpm. Optimal growth has not been found at 100 rpm. Consequently, it was determined that all of the cultures
isolated from the same fields have responded differently to environmental conditions. Future studies should be directed that pigments
extracted from Streptomyces should be investigated for various biological activities.
