Journal ArticleDOI
Production of L-dopa by Aspergillus terreus.
Sharmila Chattopadhyay,Arati Das +1 more
TL;DR: Production of L-DOPA by the activity of tyrosinase from a strain of Aspergillus terreus 104 was investigated and the parameters for optimal production with a maximum conversion of 85% of 0.1% L-tyrosine were determined.
Journal ArticleDOI
Purification and characterization of glucoamylase of Aspergillus terreus NA‐170 mutant
TL;DR: A catabolite-derepressed mutant strain of Aspergillus terreus NA-170 was isolated by multi-step mutagenesis and produced an appreciable yield of glucoamylase in the culture medium, and the enzyme was purified and was shown to be homogeneous.
Journal ArticleDOI
Improved production of citric acid by a diploid strain of Aspergillus niger.
Arati Das,Ponty Roy +1 more
TL;DR: The yield of D5 exceeded that of CGU 87 by 1.2 times and it produced 9% citric acid, which is a significant improvement and the increased productivity seems to be the result of successful adaptation of D 5 to its fermentation environment.
Journal ArticleDOI
Characterization of glucoamylase from Aspergillus terreus 4
TL;DR: A strain of Aspergillus terreus 4 was found to show extracellular amylolytic activity and the amylase was identified as glucoamylase enzyme and it was optimally active at pH 5.0 and stable between pH 3.0-8.0.
Journal ArticleDOI
Production of glucoamylase by 2-deoxy-D-glucose resistant mutant of Aspergillus terreus 4
TL;DR: A catabolite derepressed mutant of a glu coamylolytic strain of Aspergillusterreus 4 produced 1.8 times more glucoamylase than its parent; the crude enzyme preparation appreciably degraded raw starchy materials like wheat, rice, potato and barley.
