This review describes a new means of control and stimulation of microorganisms involved in the bioremediation of sediments and waterlogged soils. This emerging technology is derived from sedimentary microbial fuel cells, and consists in ensuring aerobic respiration of aerobic microbial populations in anaerobic conditions by means of a fixed potential anode in order to evacuate the ?PaperID= We show that glycolate oxidase (GLO) physically interacts with catalase (CAT) in rice leaves, and that the interaction can be deregulated by salicylic acid. We propose that the physical association–dissociation of GLO and CAT, in response to environmental stress or stimuli, serves as a specific mechanism to modulate H2O2 levels in ://(16)

Environmental Protection Agency,  (OCoLC) Material Type: Government publication, National government publication, Internet resource Hydrogen peroxide, which is commonly used as an oxygen source for in situ biodegradation, tends to decompose into water and oxygen gas. The rate of this decomposition relative to the oxygen demand of the contaminated aquifer is important to the success of an in situ process.

In the presence of oxygen, the probiotic lactic acid bacterium Lactobacillus johnsonii NCC excretes up to 1 mM H2O2, inducing growth stagnation and cell death.
