Transcriptome response to different carbon sources in Acetobacter aceti

ABSTRACT: Acetic acid bacteria are obligately aerobic alphaproteobacteria that have a unique ability to incompletely oxidize various alcohols and sugars to organic acids. The ability of these bacteria to incompletely oxidize ethanol to acetate has been historically utilized for vinegar production. The mechanism of switching between incomplete oxidation and assimilatory oxidation and the control of energy and carbon metabolism in acetic acid bacteria are not fully understood. To understand the physiology and molecular biology of acetic acid bacteria better, we determined the draft genome sequence of Acetobacter aceti NBRC 14818, which is the type strain of the genus. Based on this draft genome sequence, the transcriptome profiles in A. aceti cells grown on ethanol, acetate, glucose, or mix of ethanol and glucose was determined by using NimbleGen Prokaryotic Expression array (4x72K).

Acetobacter aceti NBRC14818 was cultivated in the medium containing ethanol, acetate, glucose, or mix of ethanol and glucose as carbon sources in Erlenmeyer flask with rotary shaking. Total RNA was extracted when optical density at 600 nm was 0.3-0.4. The experiment was performed in duplicate independent cultures.

Specific growth rate dependent transcriptome profiling of Escherichia coli K12 MG1655 in accelerostat cultures

Project description:Specific growth rate dependent gene expression changes of Escherichia coli K12 MG1655 were determined by microarray and real time PCR analyses. The bacteria were cultivated on glucose limited minimal medium using the accelerostat method (A-stat), where starting from steady state conditions in a chemostat culture, dilution rate is constantly increased. At specific growth rate (μ) 0.47 h-1, E. coli had focused its metabolism to glucose utilization by down-regulation of alternative substrate transporters expression compared to μ = 0.3 h-1. It was found that acetic acid accumulation began at μ = 0.34 ± 0.01 h-1 and two acetate synthesis pathways (phosphotransacetylase-acetate kinase (pta-ackA) and pyruvate oxidase (poxB)) contributed to the synthesis at the beginning of overflow metabolism, i.e. onset of acetate excretion. On the other hand, poxB, pta and ackA expression patterns suggest that pyruvate oxidase may be the only enzyme synthesizing acetate at μ = 0.47 h-1. Down-regulation of acs-yjcH-actP operon, the resulting loss of glucose and acetate co-utilization between specific growth rates 0.3 h-1 – 0.42 h-1 and acetic acid accumulation from μ = 0.34 ± 0.01 h-1 allows one to surmise that the acetate utilization operon expression might play an important role in overflow metabolism.

Mechanism for Fe(III) Reduction in Pelobacter carbinolicus

Project description:Pelobacter carbinolicus is phylogenetically intertwined with the Geobacteraceae, a family of deltaproteobacteria which couple oxidation of organic compounds to Fe(III) reduction. Whereas Geobacter species completely oxidize organic compounds to CO2, Pelobacter species either ferment or oxidize short chain alcohols to acetate. Pelobacter species also contain far fewer c-type cytochromes, proteins which play a role in electron transfer during Fe(III) respiration, compared to their Geobacter counterparts. Keywords: two-condition comparison

Specific growth rate dependent transcriptome profiling of Escherichia coli K12 MG1655 in accelerostat cultures

Project description:Specific growth rate dependent gene expression changes of Escherichia coli K12 MG1655 were determined by microarray and real time PCR analyses. The bacteria were cultivated on glucose limited minimal medium using the accelerostat method (A-stat), where starting from steady state conditions in a chemostat culture, dilution rate is constantly increased. At specific growth rate (Î¼) 0.47 h-1, E. coli had focused its metabolism to glucose utilization by down-regulation of alternative substrate transporters expression compared to Î¼ = 0.3 h-1. It was found that acetic acid accumulation began at Î¼ = 0.34 Â± 0.01 h-1 and two acetate synthesis pathways (phosphotransacetylase-acetate kinase (pta-ackA) and pyruvate oxidase (poxB)) contributed to the synthesis at the beginning of overflow metabolism, i.e. onset of acetate excretion. On the other hand, poxB, pta and ackA expression patterns suggest that pyruvate oxidase may be the only enzyme synthesizing acetate at Î¼ = 0.47 h-1. Down-regulation of acs-yjcH-actP operon, the resulting loss of glucose and acetate co-utilization between specific growth rates 0.3 h-1 â 0.42 h-1 and acetic acid accumulation from Î¼ = 0.34 Â± 0.01 h-1 allows one to surmise that the acetate utilization operon expression might play an important role in overflow metabolism. DNA microarray analysis was performed from three A-stat cultivations, for which one has a technical replicate.

proteome saccharomyces cerevisiae by zinc sulfate addition

Project description:High concenHigh concentration acetic acid in the fermentation medium represses cell growth, metabolism and fermentation efficiency of Saccharomyces cerevisiae, which is widely used for cellulosic ethanol production. Our previous study proved that supplementation of zinc sulfate in the fermentation medium improved cell growth and ethanol fermentation performance of S. cerevisiae under acetic acid stress condition. However, the molecular mechanisms is still unclear. To explore the underlying mechanism of zinc sulfate protection against acetic acid stress, transcriptomic and proteomic analysis were performed. The changed genes and proteins are related to carbon metabolism, amino acid biosynthesis, energy metabolism, vitamin biosynthesis and stress responses. In a total, 28 genes showed same expression in transcriptomic and proteomic data, indicating that zinc sulfate affects gene expression at posttranscriptional and posttranslational levels.tration acetic acid in the fermentation medium represses cell growth, metabolism and fermentation efficiency of Saccharomyces cerevisiae, which is widely used for cellulosic ethanol production.
