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 ...

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.

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.

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.

Microbiological hydrogen (H2) thresholds in anaerobic continuous‐flow systems: Effects of system characteristics

Biotechnology and Bioengineering, Volume 120, Issue 7, Page 1844-1856, July 2023., 2023
Abstract Hydrogen (H2) concentrations that were associated with microbiological respiratory processes (RPs) such as sulfate reduction and methanogenesis were quantified in continuous‐flow systems (CFSs) (e.g., bioreactors, sediments). Gibbs free energy yield (ΔǴ ~ 0) of the relevant RP has been proposed to control the observed H2 concentrations, but ...

From Microbial Succinic Acid Production to Polybutylene Bio‐Succinate Synthesis 

Chemie Ingenieur Technik, Volume 95, Issue 4, Page 587-595, April 2023., 2023
High‐yield anaerobic production of succinic acid using metabolically engineered Corynebacterium glutamicum is demonstrated. Electrochemically purified succinic acid from neutral fermentation broth can be used for polycondensation with 1,4‐butanediol using a biocompatible zinc catalyst to finally obtain polybutylene bio‐succinate.

Changes on fecal microbiota in rats exposed to permethrin during postnatal development [PDF]

, 2016
Alteration of the gut microbiota through diet and environmental contaminants may disturb the mammalian digestive system, leading to various diseases. Because most exposure to environmentally pyrethroid pesticides such as permethrin (PERM) occurs through ...
