TL;DR: It is concluded from the high activity of ascorbate peroxidase activity and the levels of antioxidants found that this enzyme can effectively remove low concentrations of peroxides.

TL;DR: Two questions have been examined: first, whether hydrogenase in N. muscorum and A. cylindrica is an inducible enzyme and, secondly, whether there is a cooperativity between the uptake of Hz catalyzed by hydrogenase and the rate and efficiency of N*-uptake catalyzing by nitrogenase in aerobically and Hz-grown cultures of these microorganisms.

TL;DR: It suggests that H2 leaked by nitrogenase during N2 fixation can be recycled by hydrogenase, and this activity of hydrogenase is mainly found in heterocysts and is poised unidirectionally toward H2 consumption.

TL;DR: It is suggested that in cyanobacteria an effective reaction sequence for removal of hydroperoxides involves asCorbate peroxidase and recycling of glutathione and ascorbate.

TL;DR: NMR pulse-chase experiments were used to show that 13C-enriched glycogen, which had previously been accumulated by the cells under nitrogen-limited growth at low salinities, could be utilized for the synthesis of glucosylglycerol when the cells were abruptly transferred to hypersaline media, but only in the light.
