Plate screening tests were designed for the selection and isolation of mutant strains of the fungus Aspergillus awamori CMI 142717 showing over-production and constitutive synthesis of xylanase and β-xylosidase. Following mutation by N-methyl-N-nitro-N-nitrosoguanidine, nitrous acid and UV (254 nm), two generations of mutants were isolated and cultured in shake fiasks containing glucose, ball-milled oat straw or oat speit xylan as carbon source. Growth of a number of selected mutants in shake… CONTINUE READING
