“… Singh and Jha (2016b) also reported that S. marcescens grew well up to 6% NaCl. Similarly, K. rhizophila isolates had been reported to grow substantially in 5% salt medium, however, when salt concentration increased, the isolates showed a decreasing trend ( Shi et al, 2021 ). B. circulans and B. oleronius had a shorter lag phase of 8 h than the other isolates, which indicated the potential of the microbe to grow under saline conditions ( Finkel and Kolter, 1999 ).…”

Halophytic plants can tolerate a high level of salinity through several morphological and physiological adaptations along with the presence of salt tolerant rhizo-microbiome. These microbes release phytohormones which aid in alleviating salinity stress and improve nutrient availability. The isolation and identification of such halophilic PGPRs can be useful in developing bio-inoculants for improving the salt tolerance and productivity of non-halophytic plants under saline conditions. In this study, salt-tolerant bacteria with multiple plant growth promoting characteristics were isolated from the rhizosphere of a predominant halophyte, Sesuvium portulacastrum grown in the coastal and paper mill effluent irrigated soils. Among the isolates, nine halotolerant rhizobacterial strains that were able to grow profusely at a salinity level of 5% NaCl were screened. These isolates were found to have multiple plant growth promoting (PGP) traits, especially 1-aminocyclopropane-1-carboxylic acid deaminase activity (0.32–1.18 μM of α-ketobutyrate released mg−1 of protein h−1) and indole acetic acid (9.4–22.8 μg mL−1). The halotolerant PGPR inoculation had the potential to improve salt tolerance in Vigna mungo L. which was reflected in significantly (p < 0.05) higher germination percentage (89%) compared to un-inoculated seeds (65%) under 2% NaCl. Similarly, shoot length (8.9–14.6 cm) and vigor index (792–1785) were also higher in inoculated seeds. The strains compatible with each other were used for the preparation of two bioformulations and these microbial consortia were tested for their efficacy in salt stress alleviation of Vigna mungo L. under pot study. The inoculation improved the photosynthetic rate (12%), chlorophyll content (22%), shoot length (5.7%) and grain yield (33%) in Vigna mungo L. The enzymatic activity of catalase and superoxide dismutase were found to be lower (7.0 and 1.5%, respectively) in inoculated plants. These results revealed that halotolerant PGPR isolated from S. portulacastrum can be a cost-effective and ecologically sustainable method to improve crop productivity under high saline conditions.

Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is highly contagious, and the neurological symptoms of SARS-CoV-2 infection have already been reported. However, the mechanisms underlying the effect of SARS-CoV-2 infection on patients with central nervous system injuries remain unclear. Methods The high-throughput RNA sequencing was applied to analyze the transcriptomic changes in SK-N-SH cells after SARS-CoV-2 infection. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses were performed to identify the functions of differentially expressed genes and related pathways. Results A total of 820 mRNAs were significantly altered, including 671 upregulated and 149 downregulated mRNAs (showing an increase of ≥ 2-fold or decrease to ≤ 0.5-fold, respectively; p ≤ 0.05). Moreover, we verified the significant induction of cytokines, chemokines, and their receptors, as well as the activation of NF-κB, p38, and Akt signaling pathways, in SK-N-SH by SARS-CoV-2. Conclusions To our knowledge, this is the first time the transcriptional profiles of the host mRNAs involved in SARS-CoV-2 infection of SK-N-SH cells have been reported. These findings provide novel insight into the pathogenic mechanism of SARS-CoV-2 and might constitute a new approach for future prevention and treatment of SARS-CoV-2-induced central nervous system infection.

“…At the end of the salting, this indicator for the control sample was 79.27%, 7.73% lower than for SC 2. This influence is due to rapid glycolysis and the accumulation of the sour products of the metabolism of lactic bacteria, which more actively reduce the pH level, bringing it closer to the isoelectric point of the protein substances, which leads to structural changes in the protein [34], [35].…”

The influence of the starter cultures, such as Lactobacillus rhamnosus, L. plantarum, Kocuria rosea, Staphylococcus carnosus, L. plantarum, L. rhamnosus and L. paracasei, on the functional-technological and physicochemical characteristics of the pork meat during the salting is investigated in this paper. It has been proven that the use of these starter cultures in the technology of raw ba-lik products makes it possible to obtain finished products with improved quality indicators, which is promising in the food industry. It had been shown that in the pork meat samples with the starter cultures, the acidity from 5.74 pH units is more intensively decreased – to 5.52 pH units compared to the control sample (up to 5.64 pH units). Using the starter cultures based on nitrite-reducing microorganisms for the salting in 72 hours positively influenced the formation of the required colour characteristics. It had been established that the moisture-binding capacity and plasticity of the pork meat samples with the starter cultures are characterised by the increased indicators compared with the control sample – by 4.73% and 7.73% and by 2.19 cm2.g, respectively. The difference in the volatile fatty acids content in the pork meat samples with the starter cultures compared with the control sample is 22 and 33%, respectively, in 72 hours of salting. The obtained results can be used in the enterprises of the meat processing industry to produce fermented meat products, particularly raw dried logs.
