In lactic acid bacteria (LAB), stress leads to decreases of cell vitality and fermentation yield. Glutamate decarboxylase (GAD) system is regarded as one the essential acid-resistance mechanisms in LAB. However, regulation GAD not well identified genus Lactobacillus. Although potential transcriptional regulator gene located upstream genes was found several Lactobacillus species, such (L.) brevis, contribution resistance has been experimentally determined. The gadR disrupted by homologous...
A porous cellulose bioreactor with directional channels was prepared for flow catalysis. The hierarchical structure enhanced the mass transfer and improved catalytic efficiency.
The high cell density, immobilization and stability of biofilms are ideal characteristics for bacteria in resisting antibiotic therapy. CsgD is a transcription activating factor that regulates the synthesis curly fimbriae cellulose Escherichia coli, thereby enhancing bacterial adhesion promoting biofilm formation. To investigate role formation stress resistance bacteria, csgD deletion mutant ΔcsgD was successfully constructed from engineered strain E. coli BL21(DE3) using CRISPR/Cas9...
Free-living lactic acid bacteria often encounter stresses because of their organic acid-producing features. Several resistance mechanisms, such as the glutamate decarboxylase system, F 1 o -ATPase proton pump, and alkali production, are usually employed to relieve growth inhibition caused by acids. The system is vital for GAD-containing protect cells from DNA damage, enzyme inactivation, product yield loss in acidic habitats. In this study, we found that a MerR-type regulator, GlnR, was...
Mulberries, known for their high sugar content and rich bioactive compounds, have attracted attention potential health benefits. γ-Aminobutyric acid (GABA) is an amino with multiple physiological functions. To increase the GABA enhance antioxidant capacity in fermented mulberry beverages, we screened a high-yielding strain, Lactobacillus brevis S3, its probiotic properties. L. S3 demonstrated excellent tolerance to simulated gastric acid, juice, intestinal fluid, bile salts, osmotic...
Boron is an essential element for autoinducer-2 (AI-2) synthesis of quorum sensing (QS) system, which affects bacterial collective behavior. As a living biocatalyst, biofilms can stably catalyze the activity intracellular enzymes. However, it unclear how boron biofilm formation in E. coli, particularly recombinant coli with This study screened different derivatives to explore their effect on formation. The stress response was illuminated by analyzing AI-2 activity, extracellular polymeric...
γ-Aminobutyric acid (GABA) is a prevalent nonprotein amino with diverse physiological functions, attracting considerable interest in the food industry. However, current GABA-producing strains require glutamate as substrate for synthesis. Probiotics capable of de novo GABA synthesis using sugars without are crucial developing novel foods. This study employed pH indicator method to selectively screen bacteria. Nineteen fermentation liquid greater than 5 were obtained, all demonstrated ability...
γ-Aminobutyric acid (GABA) is a ubiquitous nonprotein amino that has multiple physiological functions and received significant attention in the pharmaceutical food industries. Although there are many GABA-producing bacteria, high cost of strain cultivation limits its additive raw material application. In our study, Lactobacillus hilgardii GZ2, novel strain, was investigated. We attempted to replace nitrogen sources with silkworm pupae, waste resource silk reeling industry, GYP complex...

The supplementary of Levilactobacillus brevis strains exerts anti-obesity effects by regulating gut microbiota, bile acid metabolism and gene expression pattern hepatic cells.
Influence of Mn 2+ , Mg and Ca on β-D-glucosidase activity produced by Xanthophyllomyces dendrorhous was measured. The presence could increase the change in cell morphology obviously improves growth astaxanthin biosynthesis. biomass, yield content dry reached to 3.65 g L -1 3.06 mg 0.84 at 72 h fermentation respectively, which were higher than those absence .
