The time-order metabolic relations of the accumulation of organic acids and adenosine in shake flask cultures were studied and the hypothesis of intensification of TCA cycle for the enhancement of production was suggested.

The capability of utilizing the intermediates of TCA-cycle as the sole carbon source by the multi-vitamin auxotrophic yeast Torulopsis glabrata CCTCC M202019 under the conditions of vitamins limitation was demonstrated.

Sevag method and TCA method were used to remove protein from Porphyra polysaccharide extraction respectively,and effects of different ratios of solvent volume,dosages,treating temperature and time and other main factors on protein removing were studied respectively.

Sevag method,TCA method and caroid method were chosen.
