A new high phenyl lactic acid‐yielding Lactobacillus plantarum IMAU10124 and a comparative analysis of lactate dehydrogenase gene
In this study, 120 Lactobacillus plantarum strains were demonstrated to produce PLA using high‐performance liquid chromatography. Lactobacillus plantarum IMAU10124 was screened with a PLA yield of 0.229 g L−1. Compared with all previous reports, this is the highest PLA‐producing lactic acid bacteria (LAB) when grown in MRS broth without any optimizing conditions. When 3.0 g L−1 phenyl pyruvic acid (PPA) was added to the medium as substrate, PLA production reached 2.90 g L−1, with the highest 96.05% conversion rate. A lowest PLA‐yielding L. plantarum IMAU40105 (0.043 g L−1) was also screened. It was...

Interplay among Pseudomonas syringae HrpR, HrpS and HrpV proteins for regulation of the type III secretion system
In this study, we analysed the organization of HrpRS and HrpV regulatory proteins and interplay between them. We identified one key residue I26 in HrpS required for repression by HrpV. Substitution of I26 in HrpS abolishes its interaction with HrpV and impairs interactions between HrpS and HrpR and the self‐association of HrpS. We show that HrpS self‐associates and can associate simultaneously with HrpR and HrpV. We now propose that HrpS has a central role in the assembly of the regulatory HrpRSV complex. Deletion analysis of HrpR and HrpS proteins showed that C‐terminal parts of HrpR and HrpS confer determinants ind...

Validation of reference genes for normalization of qPCR mRNA expression levels in Staphylococcus aureus exposed to osmotic and lactic acid stress conditions encountered during food production and preservation
Abstract
Staphylococcus aureus represents the most prevalent cause of food‐borne intoxications worldwide. While being repressed by competing bacteria in most matrices, this pathogen exhibits crucial competitive advantages during growth at high salt concentrations or low pH, conditions frequently encountered in food production and preservation. We aimed to identify reference genes that could be used to normalize qPCR mRNA expression levels during growth of S. aureus in food‐related osmotic (NaCl) and acidic (lactic acid) stress adaptation models. Expression stability of nine housekeeping genes was evaluated in full (LB...

Rapid degradation of Pseudomonas fluorescens 1‐aminocyclopropane‐1‐carboxylic acid deaminase proteins expressed in transgenic Arabidopsis
In conclusion, our data suggest that the plant growth‐promoting effects of bacterial AcdS proteins are potentially modulated via protein turnover inside the host plant cells. Such post‐translational modification plays a physiological role in the mutualistic interactions between microorganisms and plants in the rhizospheric and/or endospheric niche.
This study showed that in transgenic Arabidopsis plants, Pseudomonas fluorescens ACC deaminase (PfAcdS) was rapidly degraded within host plant cells, which was likely modulated by plant 26S proteasome‐mediated protein recycling systems. (Source: FEMS Microbiology Letters)
