Characterization of isolate HN6 The selected actinomycete isolate HN6 was further identified by morphological, biochemical and physiological characterization and by 16S rRNA gene sequencing. The morphological characteristics for colony, aerial and substrate mycelia and spores were studied after culturing the individual isolates on Gause’s no.1 medium at 28°C for at least 7 days HN6 was investigated for various physiological and biochemical properties including the utilization of cellulose, inositol, mannitol and seven different sugars as carbon source, starch hydrolysis, glutin liquefaction, litmus milk reaction and H2S production The cell wall type and whole-cell sugar analysis for chemical grouping of HN6 was performed as previously described
