Abstract. We investigated whether the laccase-mediator system (LMS) with 1-hydroxybenzotriazole (HBT) as a mediator could degrade high-molecular-weight polyethylene and nylon-66 membranes. The LMS markedly reduced the elongation and tensile strength of these membranes. After 3 days of treatment with the LMS, the M w of polyethylene decreased from 242,000 to 28,300, and that of nylon-66 from 79,300 to 14,700.

Due to its complexity, the degradation of lignocellulosic waste is a great challenge for sustainable development. The generation of lignocellulosic waste from various agro-based industries indicated the magnitude of problems including pulp and paper mill (effluent 150–200m 3 /ton and solid 160–450kg/ton), sugarcane molasses-based distilleries (effluent 15lit/1 lit alcohol production and 7

Use of pesticides is usually related to overproduction of crops in order to overcome worldwide demand of food and alimentary safety. Nevertheless, pesticides are environmental persistent molecules, such as the organochlorine pesticides, which are often found in undesired places.

Provides stability as well as shelf life to beer 2 Paper Industry 1. Pulp bleaching 2. The following PFOS and PFOA chemicals, with some exceptions, were used as pesticides or as EPA "Inerts" in pesticide products, until they were phased out of use since the story broke in 2000. Similarly, a reaction system composed of the fungal polyester hydrolase HiC and the lipase CalB from Candida antarctica also showed a 7.7‐fold increase in the yield of terephthalate obtained due to the concomitant degradation of MHET catalysed by CalB (Carniel et al., 2016). LMS laccase-mediator system Potential of C. rigida and its laccases in applied processes As mentioned before, C. rigida and its laccases are currently being studied in terms of their ability to degrade and/or detoxify a wide array of compounds such as industrial by-products and/or agricultural wastes.

The continuous increase in the world energy and chemicals demand requires the development of sustainable alternatives to non-renewable sources of energy. Biomass facilities and biorefineries represent interesting options to gradually replace the present industry based on fossil fuels. Lignocellulose is the most promising feedstock to be used in biorefineries.

2: Non-DoD purveyor tested most of these systems so far as required under the EPA's Unregulated Contaminant Monitoring Rule 3 or per request from DoD. For systems not tested, the DoD Components are assessing on a case-by-case basis to determine if the systems may be impacted and needs testing.
