Project description:The gene expression profile of MC4100 delta rsd with pACYC Rsd and pACYC delta BS plasmids has been analysed using whole genome oligonucleotide microarrays. Control RNA was isolated from 50ml LB cultures of MC4100 delta rsd strain with pACYC delta BS. Experimental RNA was isolated from 50ml LB cultures of MC4100 delta rsd with pACYC Rsd, for each growth condition (OD600 = 0.4: log phase, 0.9: late log phase, 1.1: transition phase, ST(OD600 = >2.0): stationary phase). The experiments performed replicate. Keywords: timecourse (overproduction of Rsd)
Project description:Streptomyces sp. M7 has demonstrated ability to remove lindane from culture media and soils. In this study, we used MS-based label-free quantitative proteomic to understand lindane degradation and its metabolic context in Streptomyces sp. M7. We identified the proteins involved in the up-stream degradation pathway. Our results demonstrated that mineralization of lindane is feasible since proteins from an unusual down-stream degradation pathway were also identified. Degradative steps were supported by an active catabolism that supplied energy and reducing equivalents in the form of NADPH. This is the first study in which degradation steps of an organochlorine compound and metabolic context are elucidate in a biotechnological genus as Streptomyces. These results serve as basement to study other degradative actinobacteria and to improve the degradation processes of Streptomyces sp. M7.
Project description:This study aimed to investigate the variations in the protein composition of Streptomyces sp. PU10 when cultivated with either Impranil (polyestere-polyurethane) or glucose as the carbon source. We analyzed both the intracellular and extracellular protein fractions to gain insights into the intricate processes involving PU degradation, intermediate metabolic pathways in PU degradation, and the connection between primary and secondary metabolism within Streptomyces sp. PU10.

Project description:Streptomyces sp. MB42 produces antimicrobial compound under the pressence of specific compounds. This experiment is to see which gene cluster upregulated during the treatment of target compound.
Project description:Investigation of whole genome gene expression level changes in early generation Caenorhabditis elegans Bristol N2 rsd-2 and Bristol N2 rsd-6 single mutants, compared to late-generation strains at 25°C and 20°C A six chip study using total RNA recovered from two separate alleles of Caenorhabditis elegans Bristol N2 rsd-2 and one allele Bristol N2 rsd-6 , in which the effects of transgeneration aging are studied in early generation animals and late generation animals at the restrictive temperature of 25°C and the permissive temperature, 20°C.
