5-Nitro-2-furylacrylic acid besides gene mutations exerts positive effects in two other tests: it induces sister chromatid exchange in hamster cells V79 and cell transformation in vitro. All the presented data concerning mutagenicity of this compound have permitted concluding that this acid cannot be recommended for use as a stabilizer of wines and other beverages.
Propionic acid bacteria were found for the first time to be capable of oxidizing n-alkanes. The value of QO2 is higher on a mixture of n-alkanes (C12--C20) than on individual hydrocarbons whose availability is determined by the length of a hydrocarbon chain: C15 and C16-alkanes are oxidized best of all; C14, C13 and C12-alkanes are oxidized at a lower rate; and alkanes whose chain comprises less than ten carbon atoms are not oxidized at all. Hexadecane is oxidized to CO2, cetyl alcohol and palmitic acid being intermediates; this suggests the existence of the monoterminal pathway for oxidation of n-alkanes in propionic acid bacteria.
