Plastic degradation by insect hexamerins: Near-atomic resolution structures of the polyethylene-degrading proteins from the wax worm saliva.

Plastic waste management is a pressing ecological, social, and economic challenge. The saliva of the lepidopteran larvae is capable of oxidizing and depolymerizing polyethylene in hours at room temperature. Here, we analyze by cryo-electron microscopy (cryo-EM) 's saliva directly from the native source.

Biomodulation of Physicochemical Parameters, Aromas, and Sensory Profile of Craft Beers by Using Non- Yeasts.

Beer is an alcoholic beverage produced by the metabolism of yeasts and made from water, malt, and hops. In recent years, the interest in craft beers has increased considerably due to the demand for new beverages and the consumer's willingness to pay higher prices. This article explores the sensorial changes produced in craft beers by using different and non- yeasts with several instrumental and sensory analyses performed.

Characterization of a Dye-Decolorizing Peroxidase from Expressed in : An Enzyme with Wide Substrate Specificity Able to Transform Lignosulfonates.

A dye-decolorizing peroxidase (DyP) from was cloned and heterologously expressed as inclusion bodies in . The protein was purified in one chromatographic step after its in vitro activation. It was active on ABTS, 2,6-dimethoxyphenol (DMP), and anthraquinoid and azo dyes as reported for other fungal DyPs, but it was also able to oxidize Mn (as manganese peroxidases and versatile peroxidases) and veratryl alcohol (VA) (as lignin peroxidases and versatile peroxidases).
