×Tofu liquid waste can be further processed to produce some useful product.
That can be kept anaerobically to produce some organic acid
The purpose of this study to know the microbial growth behavior characteristic
of liquid tofu waste which produce with different production process, such as specific
growth rate ( µ ), doubling time (td), multiplication degree (n), product yield, and efficiency
of acetic acid production. This study is also aimed to identify the acid type which produce
with different production tofu process. The liquid waste which used for this study is
obtained from tofu producer which uses acetic acid and calcium sulfate to coagulate the
tofu protein
Liquid tofu waste was incubated 24 hour, in ambient temperature(30 C). o
analysis of total cell count, glucose concentration, acetic acid concentration, and pH value
wa s evaluated in certain interval, such 0, 2, 4, 6 8, 10, 12, 14 16, 18, 20, 22, 24 hour. Acid
type identification was evaluated in some phase during fermentation process. The
observation result was plotted into a graphic which was shown the relationship of total cell
count, with glucose concentration, acetic acid concentration, and also fermentation time.
From the analysis of observation result, It can be concluded that, the specific
growth rate of liquid tofu waste with acetic acid as protein coagulator is 0,3015/hour, while
the specific growth rate of liquid tofu waste with calcium sulfate as protein coagulator is
0,2174/hour. The doubling time of liquid tofu waste with acetic acid as protein coagulator
are 2,2991 hours, while the doubling time of liquid tofu waste with calcium sulfate as
protein coagulator are 3,1877 hours. The multiplication degree of liquid tofu waste with
acetic acid as protein coagulator are 2,605 times, while the multiplication degree of liquid
tofu waste with calcium sulfate as protein coagulator are 1,880 times. The growth yield
constant (Y p/s) of liquid tofu waste with acetic acid and calcium sulfate as protein
coagulator respectively 8,1 x 10 cfu/mg and 8,1 x 10 cfu/mg. The product yield constant 9 7
(Y p/s) of liquid tofu waste with acetic acid and calcium sulfate as protein coagulator
respectively 1,7237 and 0,0306. The efficiency of acetic acid production during
fermentation of liquid tofu waste with acetic acid and calcium sulfate as protein coagulator
respectively 15,1376% and 2,5699%. Acid type identification shows that acid which was
contained in liquid tofu waste recognized as Acetic acid.
