In this paper we studied the simple history,principle,process and selective method of carrier and medium of production of acetone and butanol with fermentive method of clostridium aceto-butylicum.
本文研究了菌发酵法生产酮和简史、原理、过程,及载体和培养基选择方法。
The oil absorption value test clarifies that the surface oleophilic character of MnCO3 received on the condition that butanol, CTAB bulk ratio of 1:4 have been well improved.
吸油值测定结果表明:经与CTAB体积比为1:4体系得到碳酸锰粉表面亲油性能得到明显改善。
To continue the natural identified chemical after that,we have found that 4-(4-hydroxyphenyl)-2-butanol(Rhododendrol:RD)inhibited the melanin synthesis more than Arbutin did.
我们在探索天然化合物过程中,发现4-(4-羟苯基)-2-(杜鹃:下简称RD)抑制黑色素合成作用比熊果苷更强。
