Rotational Spectrum Of Acetoin (ch3coch(oh)ch3) [PDF]

, 2022
Acetoin (CH$_3$COCH(OH)CH$_3$) is a common additive to e-cigarette fluids. Though not toxic itself, it decomposes into diacetyl (CH$_3$COCOCH$_3$), which is known to cause lung damage.

Differences in the bacteriome of swab, saliva, and tissue biopsies in oral cancer

Scientific Reports, 2021
Microbial dysbiosis has been implicated in the pathogenesis of oral cancer. We analyzed the compositional and metabolic profile of the bacteriome in three specific niches in oral cancer patients along with controls using 16SrRNA sequencing (Illumina ...

Dual regulation of genes involved in acetoin biosynthesis and motility/biofilm formation by the virulence activator AphA and the acetate‐responsive LysR‐type regulator AlsR in Vibrio cholerae [PDF]

Molecular Microbiology, 2005
SummaryAphA is a quorum sensing‐regulated activator that initiates the virulence cascade in Vibrio cholerae by cooperating with the LysR‐type regulator AphB at the tcpPH promoter on the Vibrio pathogenicity island (VPI). To identify the ancestral chromosomal genes in V. cholerae regulated by AphA, we carried out a microarray analysis and show here that

Global Transcriptional Response of Three Highly Acid-Tolerant Field Strains of Listeria monocytogenes to HCl Stress

Microorganisms, 2019
Tolerance to acid is of dual importance for the food-borne pathogen Listeria monocytogenes: acids are used as a preservative, and gastric acid is one of the first defenses within the host.
