Project description:Microbes were isolated from frass material collected within laboratory galleries of Odontotaenius disjunctus (bessbug beetles) in the USA, and cultured on ISP2-agar for seven days at 30C. Cultures were extracted with ethyl acetate or methanol.
Project description:Three independent cultures of Methylorubrum extorquens PA1 delta cel were grown on ammonium mineral salts with either methanol or succinate provided as the sole carbon and energy source. The supernatant was subsequently extracted with acidified ethyl acetate and analyzed by LC-MS.
Project description:Enrichment culture DFE is capable of fermenting the toxic pollutant dichloromethane (DCM; CH2Cl2) into environmentally benign acetate. The dominant organism in the enrichment culture is a novel bacterium in the Peptococcaceae family, “Candidatus Formimonas warabiya” strain DCMF. This metaproteomic study analysed culture DFE during growth with four substrates – DCM, glycine betaine, choline, and methanol – all of which are primarily, if not solely, metabolised by strain DCMF.

Project description:PKS14-overexpressing strain was inoculated into PDB for 7 days. The fungal cells were extracted with methanol, and the culture broth was extracted with ethyl acetate.
Project description:The success of bottom-up proteomic analysis frequently depends on the efficient removal of contaminants from protein or peptide samples before LC-MS/MS. For a peptide clean-up workflow, the single-pot solid-phase-enhanced peptide sample preparation on carboxylate-modified paramagnetic beads (termed SP2) was evaluated for sodium dodecyl sulfate or polyethylene glycol removal from Arabidopsis thaliana tryptic peptides. The robust and efficient 40-min SP2 protocol, tested for a 10 ng, 250ng and 10µg peptide sample, was proposed and benchmarked thoroughly against the ethyl acetate extraction protocol. The SP2 protocol on carboxylated magnetic beads proved to be the robust approach even for simultaneous removal of massive sodium dodecyl sulfate (SDS) and polyethylene glycol (PEG) contaminations from AT peptide samples in respect of the LC-MS/MS data outperforming ethyl acetate extraction.
Project description:The PKS14-knockout strain was inoculated into PDB for 7 days. The fungal cells were extracted with methanol, and the culture broth was extracted with ethyl acetate.
