A new streptomycete producing diphenyl sulfone antibiotic--S. sulfonensis.

ABSTRACT

About 359 actinomycetes were isolated from 8 different natural substrates collected from different parts of Andhra Pradesh. The isolates were screened on the basis of their inhibitory effect against test organisms. Finally one potent antibiotic producer was chosen having broad-spectrum activity against Gram-positive and Gram-negative bacteria and it was found to produce a diphenyl sulfone antibiotic. On the basis of morphological, cultural, physiological and biochemical characters, the diphenyl sulfone antibiotic producer was identified as a new species and was designated as S. sulfonensis.
