Activity of Drug Combinations against Mycobacterium abscessus Grown in Aerobic and Hypoxic Conditions

Microorganisms, 2022
Infections caused by Mycobacterium abscessus (Mab), an environmental non-tuberculous mycobacterium, are difficult to eradicate from patients with pulmonary diseases such as cystic fibrosis and bronchiectasis even after years of antibiotic treatments.

The Production of γ-Aminobutyric Acid from Free and Immobilized Cells of Levilactobacillus brevis Cultivated in Anaerobic and Aerobic Conditions

Microorganisms, 2022
γ-aminobutyric acid (GABA) has several beneficial effects on human health. GABA may be produced via chemical synthesis or through microbial metabolism, and Levilactobacillus brevis is recognized as a GABA-producing species. In this study, 11 Lvb.

Identification and biotechnological characterisation of yeast microbiota involved in spontaneous fermented wholegrain sourdoughs

Journal of the Science of Food and Agriculture, Volume 103, Issue 15, Page 7683-7693, December 2023., 2023
Abstract BACKGROUND New strategies in the cereal‐based industry has brought about the elaboration of new sourdoughs with better microbial stability and safety as well as nutritional value such as those based on wholegrain flours. This has led to an increasing interest in the selection of adapted yeasts for using them as new starters.

UbiN, a novel Rhodobacter capsulatus decarboxylative hydroxylase involved in aerobic ubiquinone biosynthesis

FEBS Open Bio, Volume 13, Issue 11, Page 2081-2093, November 2023., 2023
We identified a new flavin monooxygenase, UbiN, in the alphaproteobacterium Rhodobacter capsulatus. UbiN catalyzes decarboxylation and hydroxylation reactions in ubiquinone biosynthesis under aerobic conditions. It is the first example of a decarboxylation reaction not catalyzed by UbiD, which is the sole decarboxylase known so far in ubiquinone ...

Reduction of Gold (III) and Tellurium (IV) by Enterobacter cloacae MF01 Results in Nanostructure Formation Both in Aerobic and Anaerobic Conditions

Frontiers in Microbiology, 2018
Microorganism survival in the presence of toxic substances such as metal(loid)s lies chiefly on their ability to resist (or tolerate) such elements through specific resistance mechanisms.
