The producing velocity of enzyme was in direct proportion to cell concentration in exponential growth period and to maximum biomass in stable period. So developing cells in large quantity and prolonging stable period got a high enzyme production.
指数生长期产酶生成速率与菌体浓度成正比，在稳定期产酶生成速率与菌体最大生长量成正比，所以发酵初期大量生长菌体和延长稳定期时可使酶活力提高。
