RESULTS AND DISCUSSION
Isolation of potentially probiotic bacteria from fermented rice
The number of colonies isolated from fermented red, white cooked and uncooked rice on
MRS media, MRS sorbitol and MRS- L- cysteine plates are shown in Tables 2, 3 and 4.
There were 168 colonies observed from both cooked and uncooked red and white rice on the
different MRS media used. A total of 122 colonies were studied for Gram stain reaction and
catalase tests. Three different morpho types cluster: coccus (48), diplococcus (30) and rod
(30) were observed with gram-positive and catalase negative reactions. The number of
studied colonies showed that the majority of the isolated microorganisms from fermented
rice was grape like clusters of coccus and isolated rods with similar number of diplococcus.
Karna and Barraquio (2007) found in their study of fermented milk product, That the
predominant genus was Lactobacillu sp., which comprised fifteen of twenty eight isolates
while others included Pediococcus (5), Bifidobacterium (6) and Actinomycesis israelii (2)
.274 strains of Lactobacilli sp were identified among 563 total isolates from Thai traditional
fermented food (Srikanjana et al., 2008) Another study (Silvia and Medana, 2011) reported
that fermented Romanian vegetables were rich source of LAB including 139 isolates with
rod- (95) coccoid (32), cocobacillai (11) and diplococcal (1) shapes.
