Abstract Kimchi is often stored for a long period of time diet during the winter season because it an essential side dish Korean meals. In this study pH, abundance bacteria and yeasts, bacterial communities, metabolites were monitored periodically to investigate fermentation process kimchi 120 d. Bacterial increased quickly with pH decrease after initial increase early period. After 20 d, values became relatively stable free sugars maintained at constant levels, indicating that by lactic...

Pseudoxanthomonas spadix BD-a59, isolated from gasoline-contaminated soil, has the ability to degrade all six BTEX (benzene, toluene, ethylbenzene, and o-, m-, p-xylene) compounds. The genomic features of strain BD-a59 were analyzed bioinformatically compared with those another fully sequenced strain, P. suwonensis 11-1, which was cotton waste compost. genome differed that 11-1 in many characteristics, including number rRNA operons, dioxygenases, monooxygenases, islands (GIs), heavy metal...

Experimental vaccines for the deadly zoonotic Nipah (NiV), Hendra (HeV), and Ebola (EBOV) viruses have focused on targeting individual viruses, although their geographical bat reservoir host overlaps warrant creation of multivalent vaccines. Here we explored whether replication-incompetent pseudotyped vesicular stomatitis virus (VSV) virions or NiV-based virus-like particles (VLPs) were suitable vaccine platforms by co-incorporating multiple surface glycoproteins from NiV, HeV, EBOV onto...

Cells were non-spore-forming rods showing catalase- and oxidase-positive reactions. Growth of SJ5-8(T) observed at 10-37 °C (optimum, 30 °C), pH 6.0-9.0 7.5-8.5) the presence 0-14% (w/v) NaCl 5%). Phylogenetic inference based on 16S rRNA gene sequences showed that formed tight phyletic lineage with members genus...
