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.

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 ...

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.

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.

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.

Evidence that the PatB (CnfR) factor acts as a direct transcriptional regulator to control heterocyst development and function in the cyanobacterium Nostoc PCC 7120

Molecular Microbiology, Volume 119, Issue 4, Page 492-504, April 2023., 2023
PatB: A pleiotropic transcriptional regulator controlling diazotrophy and cell speciation in multicellular cyanobacteria. Abstract Under nitrogen‐limiting conditions, the filamentous cyanobacterium Nostoc PCC7120 differentiates nitrogen‐fixing heterocysts at semi‐regular intervals along filaments generating a periodic pattern of two distinct cell types.

Safety and efficacy of a feed additive consisting of Lactiplantibacillus plantarum DSM 11520 for horses, dogs, cats and pet rabbits (Animal Probiotics Sweden AB)

EFSA Journal, Volume 21, Issue 4, April 2023., 2023
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on Lactiplantibacillus plantarum DSM 11520 when used as a technological additive (acidity regulator) in feed for horses, dogs, cats and pet rabbits. The additive is intended to be incorporated into oat‐derived products (ca.

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 ...
