Application

Application Comment Organism
synthesis chitosan produced by the enzymatic method offers the possibility of a controlled, non-degradable deacetylation process that results in a more regular pattern of deacetylation Aspergillus flavus

Expression

Organism Comment Expression
Aspergillus flavus total inhibition of CDA production when Ag2+, Co2+, Hg2+, Mn2+ and Ni2+ are added to the medium even at 5 mM concentration, Cu2+ leads to decreased enzyme production in submerged culture down
Aspergillus flavus non-ionic surfactants like Tween 40, Tween 60 and Tween 80 increase CDA production, Ca2+ also leads to increased enzyme production in submerged culture up

General Information

General Information Comment Organism
physiological function the CDA enzyme plays a significant role only during the growth phase of the fungus Aspergillus flavus
