Title : Cassava peel an unexplored lignocellulosic residue for the Xyloooligosaccharides production: Potential pretreatments
Cassava (Manihot esculenta Crantz) belongs to the Euphorbiaceae family, originally from South America. The global production of cassava in the years 2015/16 was 280 million tons. Nigeria, Thailand and Brazil are the three world's largest producers of cassava, representing approximately 40% of the total produced worldwide. The State of Santa Catarina/Brazil is among the largest producers of cassava. Cassava flour is a product with low added-value that generates residues, mainly cassava wastewater and peels. Cassava wastewater can be used for the production of mannosileritritol lipids (biosurfactant with high added-value) - biotechnological process relatively consolidated at laboratory scale; whereas cassava peels can be used for the production of xylooligosaccharides (a compound with high added-value) - concept of green chemistry for cassava chain. Therefore, the aims of this project are (I) to produce biosurfactants using a culture medium composed of cassava wastewater and biosurfactant inducers, (II) to synthesize membranes that are efficient produced biosurfactants, (III) to produce xylooligosaccharides from cassava peels, in particular alternative pretreatments as non-thermal plasma; and (IV) starced-based materials, in particular adsorbents (stabilizers) of bioactives compounds. Therefore, these approaches can lead to the concept of green chemistry for cassava flour chain.
