TL;DR
It was shown that Halanaerobium saccharolyticum and Anoxynatronum sibiricum employ fundamentally different mechanisms for the glycerol degradation in the absence of an external electron acceptor.
This review addresses current knowledge on the regulatory networks controlling glycerol metabolism in yeasts, compassing transport mechanisms, metabolic pathways, transcriptional control and enzyme regulation, and pointed out promising avenues for future research and biotechnological innovation.
Biotin serves as an essential cofactor for several carboxylation enzymes that catalyze reactions vital for cell survival and proliferation. While bacterial biotin synthesis pathways are well characterized, the mechanisms in eukaryotic organisms remain poorly understood. In Saccharomyces cerevisiae, Bio1 catalyzes the i...
Findings indicate that the F-type ATP synthase is a major generator of proton motive force, even upon aerobic growth, and demonstrate a complementary role for the electron transport chain and Nox in the bioenergetics of E. faecalis.
The feasibility of coupling photosynthetically derived acetate to heterotrophic production of a value-added bulk chemical is demonstrated, demonstrating the feasibility of coupling photosynthetically derived acetate to heterotrophic production of a value-added bulk chemical.
Results demonstrate that, under conditions where the downstream respiratory chain is rate-limiting, electron partitioning is governed by the ratio of catalytic efficiencies of NADH and G3P dehydrogenases with respect to the quinone redox ratio (Q/QH₂).
Dark fermentation of organic waste offers a means of coupling molecular hydrogen (H2) production with the bioconversion of wet organic feedstocks. However, its practical performance remains limited by unstable carbon and electron-flow distribution, substrate heterogeneity, and dynamic shifts in microbial community stru...
