Effect of fumarate on in vitro of fermentation high concentrate substrate by mixed ruminal micro-organisms of goats;

Effects of fumarate on the fermentation activity and lactic acid concentration by rumen microorganisms;

A novel pathway for pyruvate production via fumarate was found in succinimide-assimilating microorganisms.

Aspergillus wentti F-891,which had been treated with 60Co,was screened as the strain to convert fumaric acid to L-malic acid in 1000 L fermentor by submerged fermentation.

An ester plasticiser is preparred by mono-fatty alcohol andfumaric acid which are from the mixing fatty alcohol.

Influences of fumaric acid on rumen fermentation in cow were assessed synthetically.

Research Progress on the Structure and Function of Fumarases

Based on the principle of coupling reaction and separation process,free cells containing fumarase were used for producing L\|malic acid.

The production of L malic acid by cell conversion process of Proteus vulgaris is reported with emphasis on its characteristics The studies include the effects of cell culture time and conversion reaction condition on the activity of cell fumarase;and also heat and pH stability of cell fumarase.
