“…Moreover, surface degradation of pure LDPE was also observed in vitro [9] and in situ conditions [10,11] using indigenously developed bacterial consortia. The advantages of employing mixed cultures in the form of consortia unlikely to pure cultures in biodegradation have been previously demonstrated by Satlewal et al [9].…”

“…Thus, the utilization of microbial consortia offers considerable advantages in the degradation of recalcitrant compounds [12]. Considering that, Soni et al [10] and Kapri et al [13] achieved the degradation of LDPE powder using bacterial consortia after six days of incubation. Further, Kapri et al [11] descries the in situ biodegradation studies of LDPE coupons buried in the soil-bed in a beaker with the bacterial consortia proclaim the reproducibility and polyethylene degradation efficacy of the developed consortia.…”

Low density polyethylene (LDPE) is an important commodity plastic and has a wide applicability in the modern era. In virtue of their wide applicability, the generation of the huge plastic waste became a conundrum for environment and public health. Consequently, the present study was conducted for the microbial degradation of LDPE film in natural conditions using mixture of potential polymer degrading consortia. For this purpose, the talc based formulation of bacterial consortia was inoculated into soil with LDPE film for the period of three months. Fourier transform infrared spectroscopy (FT-IR) in combination with SEM revealed that the consortia incurred significant surfacial degradation of LDPE film, introduction of hydroxyl (-OH) functionality and significant shifts in fingerprint region, respectively. The potential of the consortia towards degradation of LDPE has further been ascertained through change in bulk structural characteristics using differential scanning calorimetry (DSC). Moreover, the comparative in situ biodegradation study of LDPE film in laboratory and natural conditions indicates that environmental factors like sun-light, temperature and rainfall may enhance the rate of biodegradation of the polymer in nature.

“…The participating strains have also been used in combination with other microbes to degrade HDPE (Satlewal et al, 2008), non-poronized and poronized LDPE (Soni et al, 2009). The present investigation deals with the influence of SPION particles on the LDPE biodegradation efficiency with mixed consortium.…”

Low density polyethylene (plastics) is used in different sectors of applications like building materials, packaging, consumer products and much more. Due to wide range of application, plastics are accumulating in the environment and harm the flora and fauna. LDPE-biodegradation especially by making microbial consortium will be a good choice. Super paramagnetic iron oxide nanoparticle (SPION) has varied potential applications. Studies with SPION nanoparticles have shown their ability in enhancement of polymer degradation due to accelerating growth profiling of microbes. Super paramagnetic iron oxide nanoparticles (SPION) with size ranging 10.6 nm were used and study the degradation potential of microbes. There are three consortium were used and the effect of SPION nanoparticle different on each consortium. Mixed consortium of isolated bacterial and fungal strains shows the higher degradation percentage of LDPE. Degraded products are recovered and tested by FT-IR spectrophotometer. The FT-IR spectra of LDPE have chemical bond shifting that conform degradation take place. SPION improved the exponential phase durability. SPION influence the growth profiles of LDPE degrading microorganisms and consortium to augment the biodegradation rate. The research article primarily focuses on the biodegradation where SPION acted as enhancers of biodegradation. The significance of microbial-nanoparticle interactions which can dramatically influences LDPEbiodegradation.

“…The consortium was documented to degrade synthetic polymers like epoxy and epoxy silicone blends. Moreover, the participating strains have also been used in combination with other microbes to degrade HDPE [11], non-poronized and poronized LDPE [7].
