Several strains of photoautotrophically grown Spirulina spp. contained poly-beta-hydroxybutyrate (PHB) at concentrations never exceeding a few milligrams per gram of dry weight. Under mixotrophic growth conditions in the presence of acetate, PHB reached values greater than 2.5% of dry weight. With pyruvate, no significant effect on PHB accumulation was obtained.
几种光合自养生长的螺旋藻菌株所含的聚-β-羟基丁酸酯(PHB)浓度从未超过每克干重几毫克。在存在乙酸盐的混合营养生长条件下,PHB含量达到干重的2.5%以上。对于丙酮酸盐,未观察到对PHB积累有显著影响。
