“…In Brazil, the market in PET commercial bottles produces 9 billion units/year and more than 50% are discarded in the environment and are not reused (http://www.abipet.org.br/index.html). The recycling rate of PET is a very interesting strategy for industrial organizations considering to takes into account social, economic and environmental aspects (McBean et al 2005;Barboza et al 2009;Singh et al 2009). In addition, the environmental incentive, recycling of PET as an industry is getting its driving force from the increasing value and applications of virgin and modified PET (Awaja and Pavel, 2005).…”

Background: The hydrolytic action of cutinases has been applied to the degradation of plastics. Polyethylene terephthalate (PET) have long half-life which constitutes a major problem for their treatment as urban solid residues. The aim of this work was to characterize and to improve stable the enzyme to optimize the process of degradation using enzymatic hydrolysis of PET by recombinant cutinases. Results:The wild type form of cutinase from Fusarium solani pisi and its C-terminal fusion to cellulose binding domain N1 from Cellulomonas fimi were produced by genetically modified Escherichia coli. The maximum activity of cutinases produced in Lactose Broth in the presence of ampicillin and isopropyl β-D-1-thiogalactopyranoside (IPTG) was 1.4 IU/mL. Both cutinases had an optimum pH around 7.0 and they were stable between 30 and 50ºC during 90 min. The addition of glycerol, PEG-200 and (NH4)2SO4 to the metabolic liquid, concentrated by ultra filtration, stabilized the activity during 60 days at 28ºC. The treatment of PET with cutinases during 48 hrs led to maxima weight loss of 0.90%. Conclusions: Recombinant microbial cutinases may present advantages in the treatment of poly(ethylene terephthalate) PET through enzymatic treatments.

“…Informal recyclers opened the bags and diverted plastics, metal, cardboard, and paper from the bioreactor. In this region of Argentina, only about 2-5% of the waste, predominantly plastics, is recycled (McBean et al, 2005). There was a prevalence of organic waste in the waste stream, as summarized in Table 2.…”
