Al-Holy, Lin, and Rasco (2005) investigated the effect of nisin in combination with heat treatments or antimicrobials (such as lactic acid, chlorous
acid and sodium hypochlorite) on the inhibition of Listeria monocytogenes and total mesophiles in caviar and concluded that there was no synergistic effect due to the combination of nisin with lactic acid.
But Washington State University scientists, as an option, set out to examine the antimicrobial effects of chlorous
acid against L.
molecular formula name Cl[O.sub.2] chlorine dioxide HOCl hypochlorous acid HI[O.sub.2] iodous acid Cl[O.sup.-.sub.2] chlorite ion HOI hypoiodous acid [I.sup.-] iodide ion [I.sub.2] iodine HCl[O.sub.2] chlorous
acid [H.sub.2]O[I.sup.+] protonated hypoiodous acid
In this study, lignin was removed due to the attack of Cl[O.sub.2] (generated during delignification process) directly to the aromatic ring of lignin to decompose quickly and completely to form chlorous
acid such as fumaric acid, oxalic acid and monochloroacetic acid .
Another, also widely used technology, applies chlorous
treatment of the mineral raw material containing niobium and tantalum [1,2].
