摘要
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.
