Hom tshuaj heterotrophic tuaj yeem siv cov piam thaj, fructose, sucrose, maltose, thiab cawv ua cov pa roj carbon, thiab cov protein hydrolysates, urea, thiab ammonium sulfate ua nitrogen. Cov inorganic cov ntsiab lus xav tau rau kev loj hlob thiab kev loj hlob muaj xws li P, K, thiab Mg. Nws yog nruj me ntsis aerobic thiab muaj oxidase enzymes xws li cawv dehydrogenase thiab aldehyde dehydrogenase. Yog li ntawd, ntxiv rau oxidizing cawv los tsim acetic acid, nws tseem tuaj yeem oxidize lwm yam cawv thiab suab thaj los tsim cov kua qaub thiab ketones.
Qhov zoo tshaj plaws kev loj hlob kub yog 30-35 degree, tsis kub-resistant. Qhov zoo tshaj pH rau kev loj hlob yog 3.5-6.5. Qee hom kab mob muaj peev xwm ua tau zoo rau cawv thiab acetic acid. Tsis kam rau ntsev, yog li ntxiv ntsev tom qab acetic acid fermentation tuaj yeem tsis tsuas yog kho qhov tsw ntawm vinegar, tab sis kuj tiv thaiv cov kab mob acetic acid los ntawm kev txuas ntxiv oxidize acetic acid rau hauv CO2 thiab H2O.
