Antioxidant Activity of Collagen Extracts Obtained from the Skin and Gills of sp.

Efforts aimed at reduction of fishing waste generated during the evisceration and filleting are scarce. The fishing waste is used in the production of low value-added products, such as flours or silages. It is important to visualize an alternative and profitable use of this waste, as it constitutes a serious environmental problem.

Production of hydrocarbon-degrading microorganisms using agricultural residues of L. and as carbon source.

The aim of the present study was to evaluate the potential of oils from agricultural residues, such as L. (mango) and (papaya) from the Papaloapan region, Mexico, as a carbon source for the production of hydrocarbon-degrading (hydrocarbonoclastic) microorganisms in an airlift bioreactor via a common metabolic pathway for hydrocarbons and fatty acids. Biomass growth and carbon source uptake were measured using optical density and gas chromatography, respectively.
