Abstract: | Summary Protoplast fusion was carried out between two strains ofAspergillus
niger 8-2, a fast growing culture and poor producer of glucoamylase enzyme andA.niger 8-7, a slow growing culture and good producer of the enzyme. The nonconidiating fused mass in presence of benomyl, produced fast growing segregants showing various combinations of the two parental gene markers. Some of the segregants produced up to 68% more glucoamylase than the better yielding parent 8-7. |
