The genomic and metabolic features of Leuconostoc (Leu) mesenteroides were investigated through pan-genomic transcriptomic analyses. Relatedness analysis 17 Leu. strains available in GenBank based on 16S rRNA gene sequence, average nucleotide identity, silico DNA-DNA hybridization, molecular phenotype, core-genome indicated that has been separated into different phylogenetic lineages. Pan-genome strains, consisting 999 genes core-genome, 1,432 accessory-genome, 754 unique genome, their COG...
Aromatic polyamide membranes, which are prepared by interfacial polymerization of m-phenylene diamine (MPDA) in water solution and trimesoyl chloride (TMC) organic solution, have been widely used as reverse osmosis (RO) membranes for desalination seawater. However, it has pointed out that RO weak resistance to chlorine, causing deteriorated separation performance. In this study, nanocomposite containing multi-walled carbon nanotube (MWCNT) were developed enhance the chlorine membranes. The...
In this paper, composite reverse osmosis (RO) membranes made from sulfonated poly(arylene ether sulfone) containing amino groups (aPES) and hyper-branched aromatic polyamide-grafted silica (HBP-g-silica) were prepared, with the aim of enhancing chlorination resistance improving membrane performance. The performance RO aPES HBP-g-silica was evaluated; salt rejection water flux 96% 34 L/m2/h, respectively. After test, decreased by only 14% increased 4 L/m2/h. aPES/HBP-g-silica significantly...
The taste and quality of soy sauce, a fermented liquid condiment popular worldwide, is greatly influenced by microbial metabolism during fermentation. To investigate the fermentative features ganjang (a Korean traditional sauce), batches using meju (fermented soybean) bricks solar salts were prepared, organic compounds, communities, metagenomes, metatranscriptomes quantitively analyzed Polymeric compound analysis in treated with/without inhibitors revealed that indigenous enzymes might be...
Doenjang and ganjang are secondary fermented soybean products from meju (primary product) following a complex fermentation process that separates the into solid (doenjang) liquid (ganjang) states. We performed comparative study on gas chromatography mass spectrometry-(GC-MS) spectrometry-(LC-MS) based metabolite profiling with fungal bacterial microbial community analysis of doenjang during fermentation. Metabolite data showed distinct patterns, depending process. The relative levels...
The type strains of four subspecies Leuconostocmesenteroides , L. mesenteroides subsp. cremoris dextranicum and suionicum strain DRC1506T, used as a starter culture for commercial kimchi production in Korea, were phylogenetically analyzed on the basis their complete genome sequences. Although DRC1506T shared very high 16S rRNA gene sequence similarities (>99.72 %), results analysis average nucleotide identity (ANI), silico DNA–DNA hybridization (DDH) core-genome-based relatedness indicated...
Myeolchi-aekjeot (MA) in Korea is produced outdoors without temperature controls, which a major obstacle to produce commercial MA products with uniform quality. To investigate the effects of on fermentation, pH, bacterial abundance and community, metabolites were monitored during fermentation at 15°C, 20°C, 25°C, 30°C. Initial pH values approximately 6.0, increased after 42 days, faster increases higher temperatures. Bacterial abundances rapidly all samples quick initial decreases early then...
Cereal vinegars have been used for thousands of years, especially in Asian countries. These are still produced a traditional way by spontaneous, consecutive, alcoholic and acetic acid fermentation process open vats under non-sterile conditions, which can lead to an unstable inconsistent flavor quality. The present study characterized the microbial diversity complete, Korean rice vinegar productions at two producers (A B), from steamed vinegar, applying high-throughput amplicon-based shotgun...
