ABSTRACT
Certain polyene macrolides were developed from different actinomycetes at Research and Development of Hindustan Antibiotics Limited. These antibiotics were screened for the antifungal activity against various plant pathogens. IC50 and MIC of each of the antibiotic against the plant pathogens was found out and is being reported.

Production of free amino acids by some earthworm-borne microorganisms was investigated in three different synthetic media. Among the fungi tried Gliocladium roseum and Heterocephallum aurantiacum; among bacteria screened Bacillus macerans and B. mycoides; and among actinomycetes tested Streptomyces rimosus, S. violans, S. antibiticus, S. corchorusii and S. atroolivaceus produced significant amount of free amino acids. No correlations could be observed between vegetative growth and free amino acid production.
