Electrochemical reduction of oxygen catalyzed by Pseudomonas aeruginosa [PDF]

open access: yes, 2010
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

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Food Science and Technology
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]

open access: yes, 2019
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]

open access: yesJournal of Stress Physiology & Biochemistry, 2020
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]

open access: yes, 2015
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

Maternal exposure to BPA during the perinatal period leads to imbalances in the testicular antioxidant enzymatic system and apoptosis in adult rat offspring

open access: yesAnais da Academia Brasileira de Ciências
Bisphenol A (BPA) is a widely used plasticizer that can leach from packaging, leading to contamination of food and beverages. Exposure to endocrine-disrupting chemicals during critical windows of development may lead to functional abnormalities in ...

Adaptive response to oxidative stress in the filamentous fungus Aspergillus niger B1-D [PDF]

open access: yes, 2008
In the present study, we used a recombinant filamentous fungus strain, Aspergillus niger B1-D, as a model system, and investigated the antioxidant defences in this organism.

The discovery of acatalasemia (lack of catalase in the blood) and its significance in human genetics

open access: yesProceedings of the Japan Academy. Series B, Physical and Biological Sciences
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
