Abstract: The present disclosure belongs to a promotion system for cellular protein synthesis and use thereof, and specifically relates to the technical fields of cell metabolic engineering and synthetic biology. In the present disclosure, a RNA-binding protein (RBP) AbrP is provided. On one hand, the AbrP binds to translation-promoting factors FusA, LepA, and Era separately; on the other hand, the AbrP binds to a characteristic sequence of an sRNA. A complex resulting from the combination of the AbrP and the promoting factor reaches a translation system of a target mRNA under a guidance of the sRNA, thus releasing the translation-promoting factors FusA, LepA, and Era to stimulate and promote the translation. The present disclosure can solve the current urgent need and practical application for a regulatory element or regulatory system in a positive regulatory mode in the cell metabolic engineering or synthetic biology.

Abstract: A strain of marine oil degrading bacteria, compounds obtained by fermentation and their uses are published. The name is Alcanivorax dieselolei T6-6, with preservation Number: CGMCC NO: 9033. It belongs to ?-proteobacteria, oceanospirillales, alkane degrading bacteria branch, alcanivorax category and diesel alcanivorax species. The said bacteria can be used to degrade and remove petroleum hydrocarbon, control environmental pollution, produce surfactants, reduce surface tension of water, and for other purposes; a compound can be isolated from secondary metabolites after fermentation, one of which is dieselolei T6-6, 2-amino-6-(N-2-carbonyl-4-tridecyl-cyclobutane) hexanoic acid, and it is a kind of lysine ester. The compound has emulsifying activity on different organics, antibacterial effects against Gram-positive bacteria and fungus, and a better cytotoxic activity.
