Isolation and screening of Streptomyces in soil of protected forest areas from the states of Assam and Tripura, India, for antimicrobial metabolites

Isolation and screening of antibiotic producing actinomycetes from soils in Gondar town, North West Ethiopia

“…The present study of primary screening using single streak methods indicated that, eight (26.7%) [22,24] . Observation of clear inhibition zones around the wells on the inoculated plates is an indication of antimicrobial activities of antibiotics extracted from actinomycetes against test organisms.…”

Analysis of Antarctic proteobacteria by PCR fingerprinting and screening for antimicrobial secondary metabolites

“…The reduction of new metabolites discovered has forced the search into new habitats. Poorly explored areas or unusual environments have become critical for the discovery of novel compounds and bacteria (Saadoun and Gharaibeh, 2003;Lam, 2007;Newman and Cragg, 2007;Thakur et al, 2007). Therefore, soil samples taken from the Antarctic, one of the coldest and most poorly explored regions of the world, present good potential for the discovery of novel bioactive metabolites and compounds from microorganisms like bacteria (Marinelli et al, 2004;Tindall, 2004;Taton et al, 2006).…”

“…This bacterial taxonomy has been frequently found in Antarctic soils (Aislabie et al, 2008). Soil is an intensively exploited ecological niche that harbors inhabitants, which could produce many useful bioactive natural products, like antibiotic and antifungal compounds (Thakur et al, 2007). Lately the development of antimicrobial resistance among pathogenic bacteria and fungus has become a major health concern worldwide (Dias de Oliveira et al, 2005).…”

“…Many reports have shown that careful exploration of poorly explored areas and new habitats of the world like the Antarctic, Australia, China, and Jordan could provide novel microorganisms and useful products (Moncheva et al, 2002;Saadoun and Gharaibeh, 2003). Therefore, the exploration of new habitats with poorly explored areas and unusual environments has become critical for the discovery of novel bacteria and metabolites (Lam, 2007;Newman and Cragg, 2007;Thakur et al, 2007).…”

ENZYME ACTIVITY PROFILING OF EXO -Β-1,4- GLUCANASE, ENDO-β-1,3- GLUCANASE AND PROTEASE IN STREPTOMYCES SPECIES FROM HIGHLAND, MIDLAND AND LOWLAND AREAS OF KERALA, INDIA.

“…Many evidences indicated that Streptomyces spp. have been isolated from diverse habitats like deserts (Hozzein et al, 2008), marine (Valli et al, 2012), protected forest areas (Thakur et al, 2007) etc. Very less information is available regarding variation of Streptomyces isolates between different geological land areas.…”
