Project description:Transcriptional profiling of methanotrophic bacteria (pmoA gene) in methane oxidation biocover soil by depth Three-different depth condition in methane oxidation biocover soil: top, middle and botton layer soil: genomic DNA extract. Three replicate per array.
Project description:Methanotrophic bacteria play a crucial role in mitigating methane emissions by oxidizing methane in diverse environments. However, the molecular mechanisms underlying their adaptation to salinity stress remain poorly understood. In this study, comparative proteomic analysis was performed to investigate the salinity response strategies of methanotrophic bacteria. Proteins were extracted from cultures grown under different salinity conditions and analyzed using LC–MS/MS. Protein identification and label-free quantification were performed using Proteome Discoverer. The dataset provides insights into metabolic pathways and regulatory mechanisms involved in salinity adaptation and methane metabolism in methanotrophs.
Project description:The efficacy of bacteriophages in treating bacterial infections largely depends on the phages’ vitality, which is impaired when they are naturally released from their hosts, as well as by culture media, manufacturing processes and other insults. Here, by wrapping phage-invaded bacteria individually with a polymeric nanoscale coating to preserve the microenvironment on phage-induced bacterial lysis, we show that, compared with naturally released phages, which have severely degraded proteins in their tail, the vitality of phages isolated from polymer-coated bacteria is maintained. Such latent phages could also be better amplified, and they more efficiently bound and lysed bacteria when clearing bacterial biofilms. In mice with bacterially induced enteritis and associated arthritis, latent phages released from orally administered bacteria coated with a polymer that dissolves at neutral pH had higher bioavailability and led to substantially better therapeutic outcomes than the administration of uncoated phages.
Project description:This series represents the gene expression study of phages DT1 and 2972 during the whole process of infection. Gene expression was measured at nine time intervals (0, 2, 7, 12, 17, 22, 27, 32, 37 minutes) during phage infection.
