Isolation of Bioethanol Producing Bacteria from Southern Part of Bangladesh (Sundarbans)

Satyajit Biswas

Cellulase enzyme producing bacteria are available all over
the region but besides this, mangrove forest contains highest
amount of cellulose producing bacteria. From the southern
part of Bangladesh seven types of soil sample was collected and
five types of Pseudomonas strain, six types of Bacillus strain
and five types of Enterobacteriaceae strain was found. After the
extraction of enzyme from this bacterial strain these enzymes
are taken for alcohol production. Cellulase enzyme are highly
capable of converting carbon into sugar and after fermentation
these sugars turn into alcohol or ethanol. Pseudomonas E1-P
strain, bacillus C1-Bt strain and E. coli T2-D2 strain shows
highest O.D at 540nm in the spectrophotometry test among all
the strain during the enzyme activity assay. After fermentation
of over night their alcohol producing capability was tested by
alcohol identification test. Thus, it can be deduced that mangrove
soil contains the highest cellulolytic bacteria and it can
be beneficial for bio-ethanol producing industry.
