Síntese de celulose bacteriana a partir de resíduos lignocelulósicos via evolução adaptativa
(Universidade Federal de São Carlos, 2019-05-21)
Bacterial cellulose (BC) is produced mainly by the Komagataeibacter genus. BC is a biopolymer free of impurities, built from the interlacing of cellulose nanofibers, which presents remarkable properties, such as: high ...
Formação do carbonato de glicerol por transesterificação catalítica heterogênea
(Universidade Federal de São Carlos, 2022-04-29)
The industrial production of biodiesel has generated large amounts of glycerol, transforming this co-product into raw material for other processes. Notably, glycerol carbonate has emerged as a promising substance for the ...
