A non-waste strategy for enzymatic hydrolysis of cellulose recovered from domestic wastewater.

Cellulose is a potential resource to be recovered from wastewater treatment plants (WWTP). Enzyme formulations can be employed to hydrolyze cellulose into fermentable sugars, to be further used as biochemical building blocks or reducing its recalcitrance to further treatment processes. This study proposed the production, recovery and formulation of cellulase using domestic wastewater as culture medium and its application for the hydrolysis of cellulosic residues recovered from WWTPs.

Biotechnological approaches for cocoa waste management: A review.

Cocoa beans provide raw materials for global food industries valued in excess of $47 billion in world exportations. Through on-farm processing, about 80% of cocoa fruit is discarded as residual biomass, including cocoa pod husks, cocoa bean shells and cocoa sweatings. Farmers routinely discard these residues/by-products during the initial cocoa bean processing steps, occupying vast areas and raising social and environmental concerns.

Exploring the impacts of postharvest processing on the aroma formation of coffee beans - A review.

The aim of this review is to describe the volatile aroma compounds of green coffee beans and evaluate sources of variation in the formation and development of coffee aroma through postharvest processing. The findings of this survey showed that the volatile constituents of green coffee beans (e.g.
