Biodiesel Technology Henan Nanyang technical institute and Hainan college researcher were in jointly recently ” food and ferment industry ” article of the print on the magazine says, microzyme of a kind of grease discovers in crater of big talk city, it is the new record that our country distributings is planted, can use at producing biology diesel oil.
According to introducing, use fluid of hydrolyze of wood fibre element to produce biology fuel and biology product to have important economy and environmental sense as heart thing. However, as a result of microbial cannot be used to 5 carbon candy or utilization rate is inferior, it is difficult to make presence of product of biology of melt into of resource of wood fibre element larger. Accordingly, choose the microbial bacterium individual plant that acquires tall below mixture candy condition petroliferous fat to already made one of main tasks of domain of microbial oil technology.
Researcher saves sea fining jade from me, protect booth, the five fingers hill, Le Dong, settleclear stride, 3 inferior, the depart in the soil of big talk and other places obtains 12 individual plant to produce grease microzyme individual plant, 12 kinds of feral microzyme individual plant parts to shake with what dextrose, xylose is carbolic source bottle is fostered, the result discovers number is YP-08 (hill of the five fingers) , YP-20 (protect booth) , YP-24 (protect booth) , YP-32 (big talk) individual plant produces microzyme of this 4 individual plant oil capacity is better, all can use dextrose and xylose to undertake fermenting yield oil; Mix with respect to oil output among them fat content, collect from volcano of big talk city group the ability of YP-32 of bacterium individual plant of geological park is highest.
YP-32 of “ bacterium individual plant can use dextrose to produce oil not only, still can use xylose to produce oil, and other bacterium individual plant often can be used only among them a kind of monose, it is better that accordingly its give birth to those who produce oil to use the effect. Biology of ” Nanyang technical institute and chemical project institute teach Introduction Guo Shuxian, in the fatty acid composition that this bacterium individual plant uses 5 kinds of different scale to mix candy to produce oil, oleic acid content is highest, it is palmy acid and tristearin acid next, content of these 3 kinds of fatty acid occupies the 90% above of content of total fatty acid, comprise likeness with vegetable oil fatty acid, can regard biology derv as oily source.
According to the analysis, YP-32 of bacterium individual plant is belonged to for grease yeast, it is the new record that our country distributings is planted.

Microbial grease is afterwards vegetable oil, animal fat later another can develop the new oil resource that use. Microbial grease is divided can replace outside moving vegetable oil to produce edible oil, return what can regard biology as derv to replace raw material. Get methodological photograph to compare with traditional vegetable oil, a lot of advantage of microbial grease makes its have wide industrialization application perspective. #p#·ÖÒ³±êÌâ#e#
