Samples of water hyacinth were obtained from Sidi fish farm
located in Sokoto metropolis. The samples were chopped,
dried and ground into powder. The ground water hyacinth (25
g) was introduced into Buchner flask which served as
digesters. The rumen bacteria used in this experiment was
isolated from fresh rumen content. The content was pressed
into a sterile container and immediately brought to the
Laboratory. Serial dilution was carried out and used to
inoculate nutrient agar and chocolate agar. The agar plates
were then incubated anaerobically at 37°C for 24 h. The
digesters were seeded with rumen bacteria and immersed into
water bath operated at 37°C. During the anaerobic digestion,
volume of biogas produced was recorded accordingly. This
paper, therefore, suggests ways by which water hyacinth can
be put into better use through biogas production.
Key
words:
Water hyacinth, rumen bacteria. |
