Butanone is a constituent of tobacco smoke. [17] It is an irritant, causing irritation to the eyes and nose of humans. [12] Serious health effects in animals have been seen only at very high levels. These included skeletal birth defects and low birth weight in mice, when they inhaled it at the highest dose tested (3000 ppm for 7 hours/day). [18]
Acute feeding suppression and toxicity of raspberry ketone [4-(4-hydroxyphenyl)-2-butanone] in mice Raspberry ketone (RK; [4-(4-hydroxyphenyl)-2-butanone]) is used by the food and cosmetic industry as a flavoring agent. RK is also marketed as a dietary supplement for weight maintenance and appetite control.
Different strains have been engineered for the production of butanone and 2-butanol (Table 12.2).Because meso-2,3-butanediol is the direct precursor of butanone and 2-butanol, a strain that can natively produce meso-2,3-butanediol is preferred. There are several industrial strains that can produce meso-2,3-butanediol with high tiers, such as K. pneumoniae, K. oxytoca, …
