Abstract

It has been observed that the presence of air greatly influences the assimilation of minerals, Mg++, Ca++ and PO4″' Under anaerobic condition, mineral intake for the formation of one gram of yeast cells is high as compared to that under aerobic condition.
The yield of yeast is slight in culture media which were kept under anaerobic conditions. Maximum yield of yeast cells is observed at 53.0mgm of PO4″' concentration per 200ml of the culture medium in both aerobic and anaerobic conditions.
Further, it is interesting to note that at the concentration of PO4″' in the culture medium which forms maximum growth of yeast cells, the assimilation of Ca++, Mg++ and PO4″' is least and also the consumption of sucrose and remains at a minimum. This has been found true for both aerobic and anaerobic conditions.
