evaluation of their biodegradation potential was based on the dry weight loss of
plastic stripes of plastic cup (p) and polyethylene bags (g) after culturing in submerged fermentation using ATCC medium after incubation in the following condition such as 25–30
C in shaker incubator at 120 rpm. The potential of this strains to
produce bioemulsifier and spectrophotometric assay were evaluated after 1 month of
incubation which result in the loss in dry weight in polyethylene low-density
polyethylene stripes which include 8%, 11%, 19% for (g) stripes and 6%, 9%,
15% for (p) stripes by the following strains (SSP2, SSP4, SSP 14), and spectrophotometric assay documented greatest results for polyethylene low-density polyethylene degradation, it was discovered that strains recorded SSP2 (0.08, 0.55), SSP4
(0.09, 0.65), and SSP 14 documented (0.13, 0.70) for p and g, respectively. In
conclusion, the bioemulsifier fabrication and evaluation also showed maximum
results that play significant role in biodegradation process, the outcome observed
indicates that bioemulsifier production yield by the following strains (SSP2, SSP4,
SSP14) isolates are (8.44%, 9.84%, 12.94%) for (g) stripes and (5.74%, 7.24%,
11.84%) for (p) stripes. Their study indicated that strain SSP14 is the best isolate for
polyethylene low-density polyethylene degradation which shows that Streptomyces
could be utilized for the bioremediation of polyethylene low-density polyethylene
and could be used for many other microbiological environmental science.
The application of plastic has been identified for several purposes. The release of
plastic waste has been identified as the second largest solid waste. The high
persistence of plastic in the environment has diverted the attention of numerous
scientist. In view of this, Munir et al. (2018) isolated a bacteria that could degrade
low-density polyethylene plastic. This was carried out in a mineral salt medium
broth, entailing a low-density polyethylene powder. It was discovered that 2 out of
the 10 isolate possess the capability biodegrade low-density polyethylene in a
preliminary trial. The result obtained showed that strains SP4 and SP2 possessed
that capability to decrease low-density polyethylene with the following value,
respectively, 12.06% and 10.16% after a period of 4 weeks of incubation. The
scanning electron microscopy evaluation revealed that the surface of the treated
low-density polyethylene was altered when compared to the untreated film. Furthermore, there was presence of cracks, rough outlook, and attachment of bacterial to
their surface. The presence of biodegradation of low-density polyethylene was also
affirmed by Fourier transform infrared spectroscopy evaluation. Their study indicated that the bacteria isolated from landfill could be utilized for the biodegradation
of plastic material.
Vignesh et al. (2016) evaluated the effect of fungal and bacterial strain that could
biodegrade plastic which resides in the dumped soil samples obtained from harbor
and Pallikaranai at Chennai. The plastic degrading microorganisms were screened
using opaque techniques for the fungi and bacteria. The preliminary method revealed
the presence of three fungal and bacteria species with high biodegradative potential
which was later recognized as Streptococcus sp., Aspergillus sp., Bacillus sp.,
Fusarium sp., and Pseudomonas sp. when tested using biochemical test. This was
carried out in a submerged fermentation that involves nutrient broth for bacteria
while potato dextrose broth was utilized for the fungal isolates. The potential of these
