Project description:Alicyclobacillus acidoterrestris and Alicyclobacillus suci are both guaiacol producers that can cause spoilage in products like juices. To study the genetic underpinnings of guaiacol production, transcriptomics was performed on multiple strains of A. suci and A. acidoterrestris under guaiacol production conditions in apple juice. While guaiacol production was consistently higher by A. acidoterrestris than by A. suci, the gene expression levels associated with guaiacol production (e.g., vdcC, vdcB, vdcD) showed significant variability across strains of both species, suggesting that other factors beyond vdcC transcription influence the amount of guaiacol produced. This research provides insights for beverage producers in assessing spoilage risks and developing more informed mitigation strategies.
Project description:The purpose of this study was to characterize carbon metabolism and gene regulation in Alicyclobacillus acidocaldarius during growth on monosaccharides in an effort to determine whether carbon catabolite repression was active. Chemostat studies and global transcriptome analysis were used to accomplish this goal.
Project description:To investigate the effect of miR-503 in aging associated type 2 diabetes, target genes of miR-503 need to be investigated. The global miR-322-503-351 deletion (KO) mouse was constructed, and RNA-seq was then performed on aged mouse liver and white adipose tissue (WAT).
