In a standard growing medium, the specific activities of acid-phosphatase, beta-galactosidase and beta-glucosidase of Physarum polycephalum increase during the growth of the culture. The decrease of the pH of the culture medium during the growth has no effect on the variations of these hydrolase activities. In a glucose-starved medium, the specific activity of beta-galactosidase increases up to 350% of its initial value in 24 h, whereas the specific activities of acid phosphatase and beta-glucosidase stay near their minimal level.
在标准生长培养基中，多头绒泡菌的酸性磷酸酶、β-半乳糖苷酶和β-葡萄糖苷酶的比活性在培养物生长过程中会增加。生长过程中培养基pH值的降低对这些水解酶活性的变化没有影响。在葡萄糖饥饿培养基中，β-半乳糖苷酶的比活性在24小时内增加至其初始值的350%，而酸性磷酸酶和β-葡萄糖苷酶的比活性则保持在最低水平附近。
