RESUMO
The effects of pretreatment methods of Jerusalem artichoke tubers on microbial lipids fermentation with an oleaginous yeast strain Rhodosporidium toruloides Y4 were investigated in shaking flask culture.The yeast strain accumulated substantial amount of lipids using either purple-or white-skinned Jerusalem artichoke tubers as sole carbon and energy source.When cells were cultured on the extracted juice or the acidhydrolysate,cellular lipid content reached 40%(w/w),while cultured on the pulp,the white-skinned tubershadhigher lipid productivity,yielding 12.1 g lipids per100 g dried tubers.Major fatty acid constituents of microbial lipids were those contained 16-and 18-carbon atoms based on GC analysis,which is quite similar to traditional vegetable oil.Microbial lipids prepared from Jerusalem artichoke can be applied to biodiesel production.
RESUMO
Status of research and application of traditional Chinese medicine (TCM) in intervention treatment of primary liver carcinoma in the latest three years was reviewed in this paper. The effects of TCM combining interventional therapy mainly embodied in three aspects: the anti-tumor action, the effects for treatment of embolism syndrome and the effects for preventing and treating recurrence and metastasis. And the keystone in further researches was also pointed out, it should be focused on anti-angiogenesis of tumor by TCM for better preventive and therapeutic effects on post-intervention recurrence and metastasis.
