Intshayelelo

Inongwe kancinci. Kulula ukuthabatha umswakama kwaye uzinzile phantsi kweemeko eziqhelekileyo, kodwa kulula ukuvelisa ipropionaldehyde, i-lactic acid, i-pyruvate kunye ne-acetic acid kumaqondo aphezulu. Iyaxubana namanzi, iacetone kunye neklorofomu, kwaye inyibilika kwi-ether. Umthamo obulalayo ophakathi (igundane, ngomlomo) ngu-25ml / kg.
