Isolation and characterization of actinomycetes from Brazilian tropical soils

Isolation of biologically active Actinomycetes from untouched soils: a case study from Karaj district, Iran

Actinomycetes are a source of a broad variety of secondary metabolites with diverse biological activities, such as antifungi, antibiotics and antitumorals; many of which have been developed for clinical use. In this study, 34 actinomycetes from untouched soils were isolated from Alborz Province-Iran. Evaluation ofantifungal and anti bacterial activities of these isolates, demonstrated the capab...

Method for the preferential isolation of Actinomycetes from soils.

Isolation, characterization and identification of actinomycetes from agriculture soils at Semongok, Sarawak

A total of 62 isolates of actinomycetes were isolated from 7 soil samples collected from Agriculture Research Center Semongok, Sarawak. All 62 isolates exhibited a range of colony colours (dark grey, grey, dark brown, brownish, whitish and yellowish white). All the isolates were later purified and subjected to a few enzymatic screening. Results indicate that, 48, 46 and 41 isolates showed the a...

Isolation, Optimization, and Molecular Characterization of a Lipase Producing Bacterium from Oil Contaminated Soils

Lipases have many applications in biotechnology, thanks to their ability of acylglycerides hydrolysis. They alsp possess the unique feature of acting at the lipid-water interface, which distinguishes them from esterases. Commercially useful lipases are produced by microorganisms with the extracellular lipase being produced by many bacteria including Pseudomonas. The greatest production of lipas...

Isolation and Characterization of Diazinon Degrading Bacteria from Contaminated Agriculture Soils

Background: Organic agricultural pesticides are so stable in ecosystems and biosphere. These compounds affect soil conditions and agricultural products. The aim of this study was isolation of diazinon-degrading bacteria from Kerman pistachio orchards, Southeastern Iran. Methods: Diazinon-degrading bacteria were enriched in Bushnell-Hass medium. Identification and sequencing of prevalent degr...
