Abstract
Unique lipids found in Azotobacter vinelandii cysts are derived primarily from beta-hydroxybutyrate used to induce encystment. Tracer studies with beta-[14C]hydroxybutyrate showed that the biosynthesis of these compounds during encystment began at 8 to 12 h after induction and reached maximal levels after 2 days, Seventy percent of these unique lipids were found in the central body of the cysts, and 23% were found in the exine. Pyronic compounds, which are located mostly in the central body, were degraded during germination of the cysts, but little change occurred in the phenolic compounds, which are more uniformly distributed in the cysts.
摘要
在棕色固氮菌孢囊中发现的独特脂质主要源自用于诱导包囊形成的β-羟基丁酸。用β-[14C]羟基丁酸进行的示踪研究表明，这些化合物在包囊形成过程中的生物合成在诱导后8至12小时开始，并在2天后达到最高水平。这些独特脂质的70%存在于孢囊的中央体中，23%存在于外壁中。主要位于中央体中的吡喃类化合物在孢囊萌发过程中被降解，但在孢囊中分布更均匀的酚类化合物变化不大。
