制曲热能

Heat Energy in Starter-making

自然界存在不同形式的能量,以不同形式做功。微生物在生长过程中,其细胞产生的一系列变化需要能量,其能量主要来自微生物的呼吸作用,主要表现为热能。在制曲及发酵前期,如没有外界提供的热能,细胞的酶难以激活,微生物难以生育。微生物繁殖旺盛期,呼吸强度大,生成能量多,需及时通风降温,防止烧曲,同时,及时排除微生物呼吸所积累的CO2,有利于微生物生长。(一平)

There are various forms of energy in existence in nature applying by different means.During microbial growth,the serial changes of microbial cells are in need of energy provision,the energy mostly presented as heat energy mainly coming from microbes' respiration.In starter-making and prior period of fermentation,without heat energy provided by outside environment,enzymes in cells hardly activate and microbes rarely breed.During the peak time in microbial propagation,the increasing respiration develops more heat energy,so timely ventilation and temperature drop should be done to prevent starter burning.Besides,excessive CO 2 accumulated through microbe's respiration could be removed for better microbial growth.(Tran.by YUE Yang)
