The effect of diurnal light cycles on biohydrogen production in a thermosiphon photobioreactor

AMB Express, 2023
Key points The thermosiphon photobioreactor can operate under diurnal light cycles. Diurnal light cycles reduce hydrogen productivity of R. palustris. Diurnal light cycles have little to no effect on the growth of R palustris.

UPO‐Mimetic Engineering of CYP199A4 Enables Enhanced Peroxygenase Activity via the Hydrogen Peroxide Shunt Pathway

ChemistryEurope, Volume 4, Issue 3, March 2026.
P450 goes peroxide: When one base just isn’t basic enough. Engineering a second basic residue into CYP199A4T252E boosts its peroxygenase activity but also makes it sensitive to H2O2. The double mutant F182R/T252E shows increased turnover before rapidly self‐destructing, revealing the fine balance between productive peroxide activation and oxidative ...
