Abstract: Oporto, Leonardo Ferraer, Bachelor of Science in Biology, Major in Microbiology, Cavite State University, " Screening and Characterization of Antibiotic Producing Streptomyces Isolated from the Soil " . Adviser: Dr Yolanda A. Ilagan The study was conducted to isolate, characterize, and possibly identify antibiotic producing Streptomyces from different soil samples. Thirty two out of 66 Streptomyces isolates were found to be positive for antibiotic activity based on agar plug assay. They were inhibitors to at 1 east one of the tests organisms used which included M. Iuteus S, aureas, B. subtilis. P. vulgar is, E, coli, F. fluorescence, C, crusei and niger. Ecological, morphological, cultural biochemical and physiological characterizations of these isolates showed that different species of Streptomyces thrive on different soil environment and that no significant relationship existed between the type of soil and the isolates antibiotic activity. The positive antibiotic producing isolates grew heterogeneously on the six types of media used: Bennett s Agar , Czapeck ' s Sucrose Agar, Galactose Trptone one Agar, Peptone Iron Agar, Lysine Agar and Casein Starch Agar Likewise they showed unique characteristics on the tests done.

The study was conducted to isolate, characterize, and possibly identify antibiotic producing Streptomyces from different soil samples.

Thirty two out of 66 Streptomyces isolates were found to be positive for antibiotic activity based on agar plug assay. They were inhibitors to at 1 east one of the tests
organisms used which included M. Iuteus S, aureas, B. subtilis. P. vulgar is, E, coli, F. fluorescence, C, crusei and niger. Ecological, morphological, cultural
biochemical and physiological characterizations of these isolates showed that different species of Streptomyces thrive on different soil environment and that no significant relationship existed between the type of soil and the isolates antibiotic activity.
The positive antibiotic producing isolates grew heterogeneously on the six types of media used: Bennett s Agar , Czapeck ' s Sucrose Agar, Galactose Trptone one Agar,
Peptone Iron Agar, Lysine Agar and Casein Starch Agar
Likewise they showed unique characteristics on the tests
done.
