Biodeterioration of plasma pretreated LDPE sheets by Pleurotus ostreatus

Abstract: Low-density polyethylene (LDPE) waste generates an environmental impact. To achieve the most suitable option for their degradation, it is necessary to implement chemical, physical and biological treatments, as well as combining procedures. Best treatment was prognosticated by Plackett-Burman Experimental Design (PB), evaluating five factors with two levels (0.25 mM or 1.0 gL-1 glucose, 1.0 or 2.0 mM CuSO4, 0.1 or 0.2 mM ABTS [2, 20-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)], pH 4.5 ± 0.2 or 7.0 ± 0.2 … Show more

“…According to them, this time of exposure is insufficient for other physical or chemical changes, concluding that the mechanical properties alterations, such as the reduction of breaking energy and elasticity facilitated the fungal colonization of plastic waste. The chemical and physical changes in the low-density polyethylene (LDPE) was observed after pretreated of the LDPE sheets with low discharge plasma (O 2 , 3.0 × 10 −2 mbar, 600 V) for 6 minutes [29,30]. According to authors, this pretreated was important by plastics biodeterioration by P. ostreatus.…”

“…Plant and flower grower industries produce vast quantities of organic waste (bark, sawdust, leaves, stems, fragmented flowers, among others) containing high amounts of lignin, cellulose and hemicellulose [46]. In addition, these companies use low and high-density polyethylene (LDPE and HDPE) with different purposes: packing planting material, seedling rooting, mulching, greenhouse fabrication and wrapping of product [5,6].…”

“…To carry out simultaneous bioconversion of LCB and LDPE oxo different types of microorganisms can be used, by themselves, in co-cultures or in consortiums [1517]. From an array of microorganisms studied, lignolytic white rot fungi are the most efficient to perform partial or total biotransformation of these types of solid residues [1619] because of: ( i ) form networks of mycelia and produce exopolysaccharides that aid in colonization of both materials [6,20], ( ii ) produce an ample gamut of extracellular enzymes such as ligninases (E.C. 1.11.1.14), cellulases (E.C.…”
