Project description:Pyruvate fermentation pathway and energetics of Desulfovibrio alaskensis strain G20 under syntrophic coculture and fermentative monoculture conditions Expression data for Desulfovibrio alaskensis strain G20 grown in chemostats on pyruvate under respiratory conditions (sulfate-limited and pyruvate-limited monoculture, dilution rate 0.047 and 0.027 h-1), fermentative conditions (monoculture, dilution rate 0.036 h-1), and syntrophic conditions (coculture with Methanococcus maripaludis or Methanospirillum hungatei, dilution rate of 0.047 and 0.027 h-1)

Project description:Expression data for Desulfovibrio alaskensis strain G20 and mutants in regulator proteins grown on lactate sulfate media. Pellets collected at mid-log growth phase. We aimed to confirm or expand the predicted regulons of each of the transposon interrupted regulator mutants. 12 samples were collected: 10 regulator mutants, 1 mutant in a secretory protein and 1 control sample Desulfovibrio alaskensis G20. 1 replicate for each condition.
