2.1. Plasom preparation
The original formula of Plasom consists of 1 kg fish (Oreochromis
niloticus), 100 g table salt and 200 g sugar. The mixtures were
transferred to a bucket and covered with polyethylene film. The
containers were incubated at room temperature (30 2 C) for 8
days (Fig.1). During fermentation, each bucket was taken for LAB
isolation every two days. Prior to isolation the selected sample was
blended and used as a composite sample.
