摘要:
前期研究发现培养条件对利斯的明立体拆分的手性纯度和转化率影响很大,笔者就利斯的明立体拆分菌株季也蒙毕赤酵母(Meyerozyma guilliermondii HM988686.1的培养基组成(碳源、氮源)和其他工艺条件(培养温度、初始pH、装液量)进行了研究.通过单因素试验和正交试验,确定了该菌株的最适培养条件为蔗糖2％,蛋白胨1％,玉米浆0.5％,pH 8.0,Tris-HC1缓冲体系,培养温度28℃,装液量为100 mL/500 mL三角瓶.在最优的条件下,转化率为42％,产物ee值达95.1％.
Abstract:
Thermal efficiency, as an important indicator to measure the heating furnace advanced and the op-eration,is directly related to a level of energy consumption of the workshop production.Based on a combustionstatus of the wax oil hydrogenation unit heating furnace for Luoyang petrochemical company,some factors ofinfluence on the thermal efficiency of heating furnace were analyzed,and some improvement measures wereput forward to achieve the goal of energy saving.Furnace thermal efficiency is mainly affected by the excess airratio,exhaust gas temperature,carbon monoxide content of factors. the results show that the excess air coefi-cient increased about 6.3%,thermal efficiency reduced about 0.4% when the oxygen content is increased by1 %;amount of carbon monoxide is increased by 100 mg/L,thermal efficiency is reduced by about 0.05% ;and the exhaust gas temperature is increased by 5 ℃,the thermal efficiency of about 0.25% is lower. In or-der to improve the efficiency of the heating furnace,it is necessary that oxygen content is with in 2% ~4%, exhaust temperature is with in 125 ~135 ℃ and as low as possible for the content of carbon monoxide.
