WebAnoxygenic phototrophic bacteria play an important role in anaerobic nutritional cycles. The most readily used and widely studied carbon sources for growth of these bacteria are organic acids and a few carbohydrates. In this review we survey the growing knowledge on the metabolism of a number of oth … Webprising that the nature and availability of carbon sources are significant factors that influence denitrification. In many pure culture investigations, readily metabolized compounds such as glucose (Payne, 1981) and formate (Nishimura et aI., 1980) are used as sources of carbon. In addition, the sources and concen

WebJun 28, 2004 · Introduction. Microorganisms have developed mechanisms to regulate gene expression in response to their environment. In the filamentous fungus Aspergillus nidulans, carbon catabolism is a tightly regulated process, whereby the most energetically favourable carbon sources are used preferentially to less readily metabolized carbon sources.Three … WebEIIA Glc is preferentially dephosphorylated when E. coli cells grow rapidly with carbon sources that can be readily metabolized, such as glucose 23, 24.
