PRODUKSI RAGI KOPI KULTUR TUNGGAL: Leuconostoc mesenteroides DAN L. paramesenteroides DARI ISOLAT BAKTERI ASAM LAKTAT (BAL) KOPI LUWAK
Abstract: The presence of
microbes mainly lactic acid bacteria are thought to play a role in the process
of microbial fermentation in the digestive tract of animals during the
mongoose. Efforts need to be engineered so that the yeast fermentation of
animal dung to produce a Luwak Coffee Luwak coffee berspesifikasi high quality
based on the alleged role of lactic acid bacteria (LAB) in fermented Luwak
coffee. This research aims to produce dry yeast single culture of Leuconostoc
mesentoroides and Leuconostoc paramesentoroides with the addition of the
appropriate filler agent, and to know the level of viability of yeast products
produced during storage.The parameters observed in this study include:
calculation of bacteria using PCA (Plate Count To), water content of yeast,
sugar reduction method of Nelson-Somogy, pH and total acid. Results The study
found that the optimum filler agent for the growth of Leuconostoc mesenteroides
and Leuconostoc paramesenteroides is rice flour. Microbial population in rice
flour filler agent that is still very much during the storage in the second
appeal filler agents, namely maize and tapioca. Successive growth of
Leuconostoc mesenteroides using cornstarch, tapioaka and rice at the end of the
storage is 1.5 x 109 CFU/g, 1.7 x 107 CFU/g and 2.2 x 1010 CFU/g.
Paramesenteroides Leuconostoc populations in a row on cornstarch, tapioca and
rice is 6.3 x 1010 CFU/g, 2 x 107 CFU/g and 8.6 x 1010 CFU/g.
