Black and grey shades indicate:, positive utilization with vigorous development of mycelium substrate or vigorous spore formation, positive utilization with little development of mycelium substrate or weak spore formation, negative utilization and no development of mycelium substrate or no spore formation

The strains developed substrate mycelia on all the carbon sources, except CACIS-2.17CA. The sporulation process was weak or absent in strains CACIS-1.4CA, CACIS-1.5CA, CACIS-2.52CA and CACIS-2.17CA, and vigorous in CACIS-1.16CA and CACIS-2.19CA. Based on the morphological, biochemical, physiological data, and the characteristic earthy odor of the isolates, strains were presumptively identified as members of the genus Streptomyces.
