Summary: Benzaldehyde is an aromatic compound
also known as benzoic aldehyde belonging to the aldehydes functional group.
The compound displayed a set of absorption bands at 207, 257, 263 and 268 nm in the UV spectrum, interpreted for aromatic compound
The rubber mixture includes: 5 to 100 phr of at least one polymer A of the formula I): 1) F-[(P-Y-P-[S.sub.x]).sub.z]-P-Y-P-F, wherein S is sulfur, P is an elastomer polymer chain obtained by the anionic polymerization of a conjugated diene and, optionally, a vinyl aromatic compound
in the presence of a diinitiator, Y is a dicarbanion group derived from the diinitiator, x is an integer greater than or equal to 1 independently for each [S.sub.x] group, on the condition that x is selected from the numbers 2, 3 and 4 for at least one [S.sub.x] group, z is an integer from 1 to 160, each F is a terminal group independently selected from --H, --SH, --SOH, -SCI, -S[O.sub.2]H and -S[O.sub.3]H and at least one filler.
Mineral culture medium was prepared under anaerobic conditions and in [N.sub.2] atmosphere and was sterilized in an autoclave at 121[degrees]C/15 min (Morlett et al., 2008b) and subsequently the desired aromatic compound
was added before inoculation (10% v/v at a concentration at 1 x [10.sup.7] cells/ml).
The high concentration of aromatic compounds
may facilitate the overgrowth of aromatic compound
After collecting and analyzing the air samples, the researchers determined that two volatile fatty acids--isovaleric acid and butyric acid--and the aromatic compound
4-methylphenol were responsible for more than two-thirds of detectable beef manure odors.
