Project description:Members of the genus Acinetobacter drag attention due to their importance in microbial pathology and biotechnology. OmpA is a porin with multifaceted functions in different species of Acinetobacter. In this study we identified this protein in Acinetobacter sp. SA01, an efficient phenol degrader strain, in different cellular and sub-cellular compartments (such as OM, OMV, biofilm and extracellular environment). Differential expression of proteins, including OmpA, under two conditions of phenol and ethanol supplementation was assessed using shotgun proteomics.
Project description:Studies of expression of mechanims of defense of the Acinetobacter sp.5-2Ac.02 from airborne hospital environment under stress conditions, such as SOS response (ROS response, heavy metals resistant mechanisms, peptides), as well as Quorum network (acetoin cluster and aromatics biodegradation cluster). Characterization functional of AcoN-like as negative regulator protein from acetoin cluster in Acinetobacter spp. Strains
Project description:Transcriptional profiling of A. oleivorans DR1 cells harboring pAST2. Plasmid pAST2 is a tetracycline-resistance plasmid which was isolated from activated sludge (Hong et al., 2014). The complete plasmid sequence was deposited in the National Center for Biotechnology Information (NCBI) GenBank under accession number KC734561 [PMID: 24337108]. Acquisition of TC resistance through plasmid uptake is related to loss of biological fitness and affected host gene expression in oil-degrading soil bacterium, Acinetobacter oleivorans DR1. To identify genes in A. oleivorans DR1 harboring pAST2, the cells were grown to exponential phase (OD600 ~0.4) and total RNA was extracted using an RNeasy Mini kit (Qiagen, USA) following the manufacturer's instructions.
Project description:Petroleum hydrocarbons are recalcitrant contaminants, which has caused most serious environmental problems. Acinetobacter calcoaceticus Aca13 was isolated from petroleum polluted soil for petroleum biodegradation. Hexadecane and naphthalene were used to incubate with Acinetobacter calcoaceticus Aca13. After incubation, the whole transcriptome was obtained from treated groups and control groups, and then used for RNA sequence and analysis. Obtained data in this project will help us understand the biodegradation mechanism of hexadecane and naphthalene, and will be helpful for the bioremediation of petroleum hydrocarbons.
