Effect of dithiocarbamates on citric acid production by Aspergillus niger. 1986

V Khanna, and K G Gupta

Dithiocarbamates were found to enhance the production of citric acid under solid-state fermentation conditions by Aspergillus niger. Maximum increase was observed with tetramethylthiuram disulfide (TMTD). Percent increases observed were 74.2% with 2.5 micrograms/mL of TMTD, 19.6% with 2.5 micrograms/mL of sodium dimethyldithiocarbamate and 33.1% with 0.6 micrograms/mL of zinc dimethyldithiocarbamate.

D004125	Dimethyldithiocarbamate	A chemical that acts as a dopamine beta-hydroxylase inhibitor. Its salts are agricultural fungicides. It is inferior to diethyldithiocarbamate as a chelating agent.
D001234	Aspergillus niger	An imperfect fungus causing smut or black mold of several fruits and vegetables such as grapes, apricots, onions, and peanuts, and is a common contaminant of food.	Aspergillus lacticoffeatus
D013859	Thiocarbamates	Carbamates in which the -CO- group has been replaced by a -CS- group.	Thiocarbamate
D013893	Thiram	A dithiocarbamate chemical, used commercially in the rubber processing industry and as a fungicide. In vivo studies indicate that it inactivates the enzyme GLUTATHIONE REDUCTASE. It has mutagenic activity and may induce chromosomal aberrations.
