Biodegradation of low and high-density polyethylene by selected microorganism
P
lastic is one of the harmful and inert waste which cause serious threat to the environment especially polythene products.
So, in this suggested study an effort was prepared to develop effective consortium that polythene. Consortium was
a mixture of three fungus (
Aspergillus fumigatus, Fusarium sp.
and
Aspergillus oryzae
) and two bacteria (
Pseudomonas
stutzeri
and
Bacillus sp.
) which can mutually grow with each other. The biodegradation was calculated on the basis of dry
weight of polythene and CO
2
evolution test by shake flak method. The dry weight of polythene is major parameter to check
the biodegradation. Consortium found maximum degradation in the 60 days (18.22%) in treated High-density polyethylene
HDPE and (9.15%) non treated HDPE. On the other hand % degradation for treated Low-density polyethylene LDPE
(52.26%) and non-treated LDPE (21.51%) were higher in 90 days which is more than other single strain degradation. The
mixture of bacteria and fungi evolve high CO
2
in non-treated HDPE (92.69%) in 25 days and treated HDPE (53.33%) in
20 days. Consortium also evolved maximum CO
2
in the case of non-treated LDPE (92.48%) in 15 days and for 89.42%
for treated LDPE in 20 days.
