DOI: 10.1002/biot.70024
Abstract: While the metabolic shift in Saccharomyces cerevisiae across the Crabtree effect is well‐documented, the role of allosteric regulation in this transition remains unclear. Here, we investigated allosteric regulation by inducing a growth rate shift from… read more here.

DOI: 10.1016/j.biortech.2017.07.122
Abstract: Effect of substrate concentration on photo-fermentative hydrogen production was studied with a self-designed 4m3 pilot-scale baffled photo-fermentative hydrogen production reactor (BPHR). The relationships between parameters, such as hydrogen production rate (HPR, mol H2/m3/d), hydrogen concentration,… read more here.
