Project description:The marine obligate hydrocarbonoclastic bacterium Thalassolituus oleivorans MIL-1 metabolises a broad range of aliphatic hydrocarbons almost exclusively as carbon and energy sources. We used LC-MS/MS shotgun proteomics to identify proteins involved in aerobic alkane degradation during growth on medium- (n-C14) or long-chain (n-C28) alkanes.
Project description:To identify transcriptional adaptations associated with increased alkane production in Nostoc punctiforme, we performed comparative transcriptomic analysis of an alkane overproduction strain. RNA-seq data identified a large number of highly up-regulated genes in the overproduction strain potentially involved in rRNA processing, mycosporine-glycine production, and synthesis of non-ribosomal peptides including nostopeptolide A. Other up-regulated genes encoding helical carotenoid proteins, stress-induced proteins, and those for microviridin synthesis were also up-regulated. The presence of several up-regulated genes or operons on multi-copy plasmids resulted in reduced alkane production, indicating possible targets for mutagenesis that might limit lipid droplet and alkane production.
