Abstract

A comparative study of the amount of total and cell wall phosphorus in Bacillus megaterium ATCC 33085, grown in media with or without phosphate limitation was carried out. The phosphorus levels were investigated during six successive subcultures. A progressive decrease in total phosphorus was found in cells cultivated in a phosphate-limited medium. A decline in the cell wall phosphorus level was observed starting only from the third subculture in phosphate-limited medium, and no phosphorus was detected in the walls of cells in the fifth subculture.

摘要

对巨大芽孢杆菌ATCC 33085在有或无磷限制的培养基中生长时的总磷和细胞壁磷含量进行了比较研究。在连续六次传代培养过程中对磷水平进行了研究。发现在磷限制培养基中培养的细胞中总磷逐渐减少。仅从磷限制培养基中的第三次传代培养开始观察到细胞壁磷水平下降，在第五次传代培养的细胞细胞壁中未检测到磷。
