In this study we define ‘Good Nata’ fermentation as one
which will generate a thick (1.5-2 cm), homogenous cellulose
gel with high transparency; while ‘Bad Nata’ fermentation
will generate frothy, thin (frequently less than 0.5 cm), soft
with white or opaque color Nata gel after 8 days of fermentation
(Seumahu 2005).
