Mixed strain of free cells and different fermentative modes of batch and fed-batch fermentation were conducted to produce ethanol from dilute-acid lignocellulose hydrolysates.

In order to reduce negative effect of inhibitory compounds in bioconversion process of diluted-acid hydrolysis of lignocellulose to ethanol the fermentations were carried out with cocultures and batch,fed-batch and intermittent fed-batch fermentation methods.

With ammonia water as nertralizer,L-lactic acid batch and fed-batch fermentation by ammonia resistant mutant Rhizopus oryzae JS-N02-02 were conducted in a 15L fermentor.

Optimization of the fed-batch fermentation process of hyaluronic acid (HA)produced by Streptococcuszooepidemicus was studied.

Study on fed-batch fermentation conditions of L-isoleucine;

The optimum condition of fed-batch fermentation of CoQ10 was confirmed.

Then in according to the above optimal conditions,batch fermentation and fed-batch fermentation were carried out.

Trehalose accumulation condition in baker's yeast was studied in fed batch fermentation.

Flask-shaking fed batch fermentation is carried out by feeding 1.

Flask -shaking fed batch fermentation is carried out in the study by feeding glucose,peptone,monosodium glutamate and complete fermentation medium.
