Reduction of soluble and insoluble iron forms by membrane fractions of Shewanella oneidensis grown under aerobic and anaerobic conditions

Article Abstract:

The effect of iron substrates and growth conditions on in vitro dissimilatory iron reduction by membrane fractions of Shewanella oneidensis MR-1 is characterized. The ability of Shewanella to utilize iron oxide as the terminal electron acceptor, a process referred to as dissimilatory iron reduction (DIR) is extensively studied.

Effect of pH and oxalate on hydroquinone-derived hydroxyl radical formation during brown rot wood degradation

Article Abstract:

Results indicate that hydroquinone is very stable at pH 2 to 4, the pH of degraded wood. It is important for hydroxyl radical formation and oxalate serves as a sequestering agent. Data show that the formation of hydroxyl radical occurs through the hydroquinone redox cycle.
