THE HYPERSUSCEPTIBLE ANTIBIOTIC SCREENING STRAIN STAPHYLOCOCCUS AUREUS SG511-BERLIN HARBORS MULTIPLE MUTATIONS IN REGULATORY GENES

The hypersusceptible antibiotic screening strain Staphylococcus aureus SG511-Berlin harbors multiple mutations in regulatory genes

The genetic plasticity of Staphylococcus aureus has facilitated the evolution of many virulent and drug-resistant strains.Here we present the sequence of the 2.74 Mbp genome of S.aureus SG511-Berlin, which is frequently used for antibiotic screening.Although S.aureus SG511 and the related methicillin-resistant S.aureus MRSA252 share a high similari

A calculation method for the efficiency of hydrocarbon expulsion based on parameter-diagram of source rock pyrolysis

The efficiency of hydrocarbon expulsion acts as Roping saddle a key geological factor for the study of hydrocarbon expulsion of conventional oil and gas, also, it indicates the enrichment degree of unconventional oil and/or gas.Based on the method of recovering the original hydrocarbon generation potential, a method according to pyrolysis chart was
