3.6. Physiological and biochemical characteristics of isolates
Physiological and biochemical characteristics result indicates that all isolates showed the ability of starch and urea hydrolysis. The isolates from LT001 to LT005 were able to hydrolysis celatin; LT001 to LT003 and LT005 to LT008 were able to hydrolysis casein. The positive utilization of citrate was recorded in LT001, LT003, LT005, LT006 and LT009. The tested actinomycetes showed resistance capacity to grow in 5% concentration of sodium chloride. The optimum temperature for the growth of most isolates was between 25-30 °C and LT008 exceed up to 40 °C
