Recent development in low-moisture foods: Microbial safety and thermal process

Food Research International, Journal Year: 2022, Volume and Issue: 155, P. 111072 - 111072

Published: Feb. 28, 2022

Foodborne outbreaks and recalls of pathogen-contaminated low-moisture foods (LMFs, with water activity at 25 °C < 0.85) have led to numerous scientific studies on bacterial persistence, as well newly developed industrial interventions. Conducting microbial tests LMFs, lab tests, or validation in pilot plans requires complete information protocols parameters that need be aware of—in particular, understanding how factors influence the thermal resistance pathogen LMFs is critical designing any processes. This review provides detailed general LMFs: from pertinent identification studies. In it reviewed procedures (e.g., lawn-harvest method), analytical recovery enumeration pathogens LMFs), specialized tools been utilized (even widely accepted) laboratory-based LMFs. It also summarized article could support intervention existing pasteurization processes LMF industry, promoting safety

New insight into the mechanisms protecting bacteria during desiccation

Current Genetics, Journal Year: 2019, Volume and Issue: 66(2), P. 313 - 318

Published: Sept. 26, 2019

Desiccation is a common stress that bacteria face in the natural environment, and thus, they have developed variety of protective mechanisms to mitigate damage caused by water loss. The formation biofilms accumulation trehalose sporulation are well-known strategies used survive desiccation. Other mechanisms, including intrinsically disordered proteins anti-glycation defence, been mainly studied eukaryotic cells, their role remains unclear. We recently shown impairment synthesis results higher glucose availability, leading acetyl phosphate enhanced protein acetylation, which turn stimulates aggregation. In absence synthesis, excess may stimulate non-enzymatic glycosylation advanced glycation end products (AGEs) bound proteins. Therefore, we propose prevent damage, not only as chemical chaperone but also metabolite indirectly counteracts detrimental acetylation glycation.

Osmolyte-Induced Folding and Stability of Proteins: Concepts and Characterization.

PubMed, Journal Year: 2019, Volume and Issue: 18(Suppl1), P. 13 - 30

Published: Jan. 1, 2019

It is well-known that the typical protein's three-dimensional structure relatively unstable in harsh conditions. A practical approach to maintain folded state and thus improve stability activity of proteins unusual circumstances directly apply stabilizing substances such as osmolytes protein-containing solutions. Osmolytes natural occurring organic molecules typically called "compatible" solutes, based on concept they do not perturb cellular components. However, urea guanidine hydrochloride (GuHCl) denaturing destabilize many macromolecular structures inhibit functions. Several studies have been so far performed explain actual interaction an osmolyte with a protein. The present review aimed achieve collective knowledge progress arise field osmolyte-protein interactions. following also overview main techniques measure protein presence osmolytes.

Plant Transcriptome Reprograming and Bacterial Extracellular Metabolites Underlying Tomato Drought Resistance Triggered by a Beneficial Soil Bacteria

Metabolites, Journal Year: 2021, Volume and Issue: 11(6), P. 369 - 369

Published: June 9, 2021

Water deficit is one of the major constraints to crop production and food security worldwide. Some plant growth-promoting rhizobacteria (PGPR) strains are capable increasing drought resistance. Knowledge about mechanisms underlying bacteria-induced resistance important for PGPR applications in agriculture. In this study, we show stress-mitigating effects on tomato plants by Bacillus megaterium strain TG1-E1, followed profiling transcriptomic responses TG1-E1 bacterial extracellular metabolites. Comparison between transcriptomes drought-stressed with without inoculation revealed transcriptome reprograming, highlights differentially expressed genes belonging functional categories including transcription factors, signal transduction, cell wall biogenesis organization. Mass spectrometry-based analysis identified over 40 metabolites, several regulators or osmoprotectant precursors These results demonstrate importance transcriptional regulation metabolites PGPR-induced
