Electrochemical reduction of oxygen catalyzed by Pseudomonas aeruginosa [PDF]
Pseudomonas aeruginosa has already been shown to catalyze oxidation processes in the anode compartment of a microbial fuel cell. The present study focuses on the reverse capacity of the bacterium, i.e. reduction catalysis. Here we show that P. aeruginosa

Microbial Diversity of Aquatic Environment as Source of Enzymes
This research consisted of studying the ability of new strains of microorganisms isolated from water of the "La izvor" lake system to synthesize enzymes: amylase, catalase, cellulase, lipase and selecting those with significant enzymatic potential ...

Characterization of peroxidase and catalase genes in defense mechanisms of Physcomitrella patens [PDF]
Systemic acquired resistance (SAR) and the hypersensitive response (HR) are two important induced defense mechanisms in plants. SAR is the development of an enhanced resistance to a pathogen due to a prior encounter.

Role of Pre-Sowing Gamma-Irradiation of Seeds in the Salt-Resistance of Phaseolus vulgaris L. [PDF]
Studies of the effect of low-dose γ-radiation on the resistance of plants to abiotic stresses have recently attracted great attention of researchers due to the constant environmental degradation. In separate examples, it was shown that γ-radiation in low

Genomic and proteomic evidences unravel the UV-resistome of the poly-extremophile Acinetobacter sp. Ver3 [PDF]
Ultraviolet radiation can damage biomolecules, with detrimental or even lethal effects for life. Even though lower wavelengths are filtered by the ozone layer, a significant amount of harmful UV-B and UV-A radiation reach Earth?s surface, particularly in

The discovery of acatalasemia (lack of catalase in the blood) and its significance in human genetics
Catalase, a heme-containing antioxidant enzyme, was once considered essential for human survival. It is widely distributed in the human body and is particularly abundant in red blood cells. The term “acatalasemia” first appeared in the Proceedings of the
