Sugar uptake was maximum at pH 9.5 and 7.5 for S. brevicaulis and S. piriforme respectively. Amino-n content showed significant decrease in the case of S. piriforme with the increase in pH value, while differences were not significant in the case of S. brevicaulis. Polysaccharide content of S. brevicaulis significantly decreased with the increase in pH value, while that of S. piriforme was insignificantly affected. Considering nitrogenous contents, there was a clear relation in the case of S. brevicaulis, as the total insoluble nitrogen increased by the rise in pH value, total soluble nitrogen decreased. On the other hand, significant decrease of both components was observed in the case of S. piriforme.]]>Bansod, S.M., M. Dutta-Choudhary, M.C. Srinivasan and M.V.
