Guava-flavored whey beverage processed by cold plasma technology: Bioactive compounds, fatty acid profile and volatile compounds.

Marcello R Silveira et al.

Food chemistry, 279, 120-127 (2019-01-07)

The effect of cold plasma processing time and gas flow on bioactive compounds such as vitamin C, carotenoids and phenolic compounds, DPPH, angiotensin-converting-enzyme (ACE) inhibitory activity, fatty acids profile, and volatile compounds of guava-flavored whey beverage was investigated. For comparative

Enhanced production of 2,3-butanediol by engineered Bacillus subtilis.

Ranjita Biswas et al.

Applied microbiology and biotechnology, 94(3), 651-658 (2012-03-01)

Production of 2,3-butanediol by Bacillus subtilis takes place in late-log or stationary phase, depending on the expression of bdhA gene encoding acetoin reductase, which converts acetoin to 2,3-butanediol. The present work focuses on the development of a strain of B.

Enterotoxigenicity of Staphylococcus intermedius of canine origin.

E Y Hirooka et al.

International journal of food microbiology, 7(3), 185-191 (1988-12-01)

Seventy-three staphylococcal strains isolated from pyrodermatitis in dogs were classified as Staphylococcus intermedius (52 strains) or Staphylococcus aureus (21 strains) on the basis of acetoin formation, anaerobic mannitol fermentation, aerobic maltose fermentation, pigmentation, coagulation of human plasma, and reaction on

Acetoin metabolism in bacteria.

Zijun Xiao et al.

Critical reviews in microbiology, 33(2), 127-140 (2007-06-15)

Acetoin is an important physiological metabolite excreted by many microorganisms. The excretion of acetoin, which can be diagnosed by the Voges Proskauer test and serves as a microbial classification marker, has its vital physiological meanings to these microbes mainly including

The transcriptional response of Listeria monocytogenes during adaptation to growth on lactate and diacetate includes synergistic changes that increase fermentative acetoin production.

Matthew J Stasiewicz et al.

Applied and environmental microbiology, 77(15), 5294-5306 (2011-06-15)

The organic acids lactate and diacetate are commonly used in combination in ready-to-eat foods because they show synergistic ability to inhibit the growth of Listeria monocytogenes. Full-genome microarrays were used to investigate the synergistic transcriptomic responses of two L. monocytogenes
