Can biomass mastication assist the downstreaming of polyhydroxyalkanoates produ...
Souza, Hiléia Karla Silva; Matos, Mariana; Reis, Maria A. M.; Covas, J. A.; Hilliou, L.Polyhydroxyalkanoates (PHAs) are natural polyesters which biodegrade in soils and oceans but have more than double the cost of comparable oil-based polymers. PHA downstreaming from its biomass represents 50% of its overall cost. Here, in an attempt to assist downstreaming, mastication of wet biomasses is tested as a new mechanical continuous biomass pretreatment with potential for industrial upscaling. Downstre...
Phenolic extraction of Moringa oleifera leaves in DES: characterization of the ...
Braham, Fazia; Amaral, Luísa M. P. F.; Biernacki, Krzysztof; Carvalho, Daniel O.; Guido, Luis F.; Magalhães, Júlia M. C. S.; Zaidi, FaridIn this work, a qualitative study of the phenolic content of <i>Moringa oleifera</i> leaves (MO), extracted with deep eutectic solvents (DES) based on choline chloride (ChCl) with lactic acid (LA) or glycerol (GLY), was performed by high-resolution mass spectrometry (HPLC-DAD-ESI-MS<sup>n</sup>). The two solvents (DES-LA and DES-GLY) extract similar classes of phenolics, and ten compounds were identified. The a...
