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 ability to secrete cellulase, lipase and protease respectively. All 62 isolates were then subjected to… Expand
