use of heat mutant results in increased thermostability with optimal activity. The mutagenesis confers increased thermostability up to 70°C till 60 min, with 82.7% residual tannase activity Aspergillus foetidus

Expression

Organism Comment Expression
Aspergillus foetidus fall in tannase activity from day 7 to 10 is suggestive of a possible tannase inhibition probably by repression down
Aspergillus foetidus parent strain produces 19.5 U/ml at 72 h of fermentation time in submerged culture. Mutagenesis exerts a positive effect on the strain producing 1.5-2fold increase in tannase production. The heat IV mutant exhibits the highest tannase activity of 38.9 U/ml at 48 h additional information
Aspergillus foetidus higher titres of tannase with 2.5-2.8fold increase in tannase activity by solid state fermentation up
