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.

Exploring the denitrification proteome of Paracoccus denitrificans PD1222 [PDF]

, 2018
Denitrification is a respiratory process that produces nitrous oxide as an intermediate, which may escape to the atmosphere before its reduction to dinitrogen through the nitrous oxide reductase NosZ. In this work, the denitrification process carried out

Transcriptome and proteome dynamics in chemostat culture reveal how Campylobacter jejuni modulates metabolism, stress responses and virulence factors upon changes in oxygen availability [PDF]

, 2017
Campylobacter jejuni, the most frequent cause of food-borne bacterial gastroenteritis worldwide, is a microaerophile that has to survive high environmental oxygen tensions, adapt to oxygen limitation in the intestine and resist host oxidative attack ...

The pneumococcal response to oxidative stress includes a role for Rgg [PDF]

, 2009
Streptococcus pneumoniae resides in the oxygen-rich environment of the upper respiratory tract, and therefore the ability to survive in the presence of oxygen is an important aspect of its in vivo survival. To investigate how S.

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.

Stress Response of Vibrio parahaemolyticus and Listeria monocytogenes Biofilms to Different Modified Atmospheres

Frontiers in Microbiology, 2020
The sessile biofilms of Vibrio parahaemolyticus and Listeria monocytogenes have increasingly become a critical threat in seafood safety. This study aimed to evaluate the effects of modified atmospheres on the formation ability of V.

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 ...

Screening of yeast co‐culture using crude hydrolysate for co‐fermentation of pentose and hexose

Biofuels, Bioproducts and Biorefining, Volume 17, Issue 6, Page 1639-1653, November/December 2023., 2023
Abstract The use of all sugars from biomass fractionation – that is, hexoses and pentoses – is essential to develop feasible processes in a biorefinery context. Hexoses are converted into different products by most microorganisms. The main issue is the conversion of pentoses, especially when mixed with hexoses.
