A linear relationship between total solid concentration (TSC), delta-endotoxin production [Cry = 0.2795(TSC)-0.2472, R2 = 0.8644] and poly-beta-hydroxybutyrate (PHB) accumulation [PHB = 0.1327(TSC) + 0.3974, R2 = 0.9877] in Bacillus thuringiensis var. kurstaki HD-73 was observed. A similar correlation between delta-endotoxin and PHB accumulation [Cry = 2.1573(PHB)-1.1248, R2 = 0.9181] was found. A minimum PHB accumulation of 0.52 mg l(-1) was required before the onset of delta-endotoxin production.
在苏云金芽孢杆菌库斯塔克变种HD-73中，观察到总固体浓度（TSC）、δ-内毒素产生[Cry = 0.2795(TSC) - 0.2472，R2 = 0.8644]和聚-β-羟基丁酸酯（PHB）积累[PHB = 0.1327(TSC) + 0.3974，R2 = 0.9877]之间存在线性关系。还发现δ-内毒素与PHB积累之间存在类似的相关性[Cry = 2.1573(PHB) - 1.1248，R2 = 0.9181]。在δ-内毒素产生开始之前，PHB积累的最小值为0.52 mg l(-1)。
