研究了醋杆菌细胞质提取物的乙醛脱氢酶活性。使用基于乙醇或葡萄糖的两种不同培养基来比较菌株生长和活性。的酶活性的动力学常数已被确定为从乙醇上生长的菌株的提取物。最后，研究了酶的自发失活过程，其动力学符合一级动力学。
The aldehyde dehydrogenase activity of the cytoplasmatic extracts of a A cetobacter aceti strain used industrially in vinegar production is investigated. Two different culture media, based on ethanol or glucose, were used to compare the strain growth and activity. The kinetic constants of the enzymatic activity have been determined for extracts from the strain grown on ethanol. Finally, a study has been made of the spontaneous enzyme de-activation, which seems to fit a first order kinetic.
