“…The upper part of the column has wider diameter which permits the reduction of the foam height at the surface and will facilitate the sedimentation [33] of the bacterial culture in order to reduce the removal of these along the finished product. The air is supplied from a compressor and passes through a diffuser (perforated plate) at the base of the column by which aeration and mechanical agitation are attained.…”

“…Hal demikian terjadi karena semakin tinggi konsentrasi alkohol maka kadar asam asetat yang dihasilkan juga semakin tinggi, tetapi peningkatan konsentrasi alkohol lebih lanjut justru akan menghambat pertumbuhan bakteri Acetobacter aceti. Hotmaka dan Ebner (1995), menyatakan bahwa kadar alkohol yang baik digunakan sebagai substrat dalam fermentasi asam asetat adalah sebesar 5-7 %. Sementara itu, perlakuan penambahan alkohol 10 dan 12 % (v/v) diperoleh kadar alkohol awal substrat sebesar 4,68 dan 6,48 % (Tabel 2), sehingga perlakuan tersebut dapat menghasilkan cuka kakao dengan kadar asam asetat relatif lebih tinggi.…”

“…Pada perlakuan penambahan alkohol tersebut diperoleh kadar alkohol awal substrat sebesar 4,68 dan 6,48 % (Tabel 2). Hal demikian sejalan dengan temuan Hotmaka and Ebner (1995), yang menyatakan bahwa kadar alkohol yang baik sebagai substrat fermentasi asam asetat adalah sebesar 5-7 %. Hal ini ditunjukkan pula oleh aktivitas bakteri tersebut dalam merombak alkohol menjadi asam asetat yang terus meningkat.…”

“…While observing through an eyepiece, the scale-calibrated screw was rotated so that boundary line separating the light and the dark areas of the image was aligned. Yield of acetification fi 7 : This was calculated as the change in acid during fermentation expressed as a percentage of the original alcohol content of the vinegar stock.…”

“…Initially, the most important design feature of an Acetator was its self-priming aerator 6 . The most common technology in the actual vinegar industry till date is based on the submerged acetification fi 7 wherein a stirred medium containing 8-12 percent alcohol (hard, cider, wine fermented malt mash or spirits) was inoculated with Acetobacter and held at 24 to 29 r o C with controlled aeration by means of fi nely divided air. Very little research fi on acetic acid bacteria has been done by the wine industry world-wide 8 .…”
