DOI: 10.1016/j.bej.2017.03.019
Abstract: Abstract In Rhodobacter sphaeroides, synthesis of coenzyme Q10 (CoQ10) shares the same precursor geranylgeranyl diphosphate (GGPP) with carotenoids. Therefore, suppression of carotenoids synthesis is supposed to pose positive effects on accumulation of CoQ10. In this… read more here.

DOI: 10.1016/j.ijhydene.2020.09.184
Abstract: Abstract Selection of the source for biohydrogen (H2) production is essential, since it affects bacterial metabolism. Pure organic substrates give fast H2 generation with high yields, but they increase the production cost. Using industrial wastes… read more here.

DOI: 10.1073/pnas.2010087117
Abstract: Significance Bacterial promoters are often predicted by similarity to the Escherichia coli −10 and −35 consensus elements. Although these elements are highly conserved in diverse bacterial phyla, only 30 to 43% of promoters we analyzed… read more here.
