A continuous culture system was developed to examine the cell surface carbohydrates of Bradyrhizobium sp. strain 32H1. When cultures were shifted from aerobic to microaerobic growth conditions, nitrogenase activity was induced and extracellular polysaccharide levels were greatly reduced; however, the levels of cell-associated cyclic beta-1,6 -1,3 glucans were found to be essentially unchanged.
开发了一种连续培养系统来检测慢生根瘤菌属32H1菌株的细胞表面碳水化合物。当培养物从有氧生长条件转变为微需氧生长条件时,固氮酶活性被诱导,胞外多糖水平大幅降低;然而,发现细胞相关的环状β-1,6 -1,3葡聚糖水平基本未变。
