succinogenes needs valeric acid
and isobutyric acid .
and butyric acid decreased significantly in T1 and T2 while isovolaric acid and the ratio of acetic acid and propionic acid and glucose increased significantly in T1.
Most identified enhancers can be classified as: alcohols (ethanol, pentanol, benzyl alcohol, lauryl alcohol, propylene glycols and glycerol), fatty acids (oleic acid, linoleic acid, valeric acid
and lauric acid), amines (diethanolamine and triethanolamine), esters (isopropyl palmitate, isopropyl myristate and ethyl acetate), amides (1-dodecylazacycloheptane-2-one [AzoneA(r)], urea, dimethylacetamide, dimethylformamide and pyrrolidone derivatives), hydrocarbons (alkanes and squalene), surfactants (sodium laureate, cetyltrimethylammonium bromide, BrijA(r), TweenA(r) and sodium cholate), terpenes (D-limonene, carvone and anise oil), sulfoxides (dimethyl sulfoxide) and phospholipids (lecithine).
The acid is different from the chelating agent and is selected from the group consisting of glycolic acid, citric acid, lactic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid
, caproic acid, gluconic acid, itaconic acid, trichloroacetic acid, benzoic acid, urea hydrochloride, and combinations thereof.
From decomposed sewage or wastewater in these cesspits, inorganic acids including hydrogen sulfide or organic acids including acetic acid and valeric acid
may be produced, and these acids accelerate corrosion of concrete.
has been widely used in perfumes and cosmetics industries due to its pleasant odour.
4,4,-Bis(4-hydroxyphenyl) valeric acid
and 4-fluoro benzoic acid were purchased from Sigma-Aldrich and used as received.
For juniper, isovaleric acid was detected in the second replicate but not the first, while valeric acid
was detected in the first but not the second.
Among them were alkanes, 4 phenyl valeric acid
, 5 isopentyl picolinic acid, 3 hydroxylauric acid, (5 a, 3[beta]) 3-hydroxy-11-androstanone, 5[alpha]-2-en-11 androstenone, squalene, terpinol (a terpineol), menthol derivatives, palmitic, oleic and eicosanoic acids, and isoprenoid phytane.
