3. Production of a long chain fatty alcohol concentrate from saponified and acidulated sugarcane wax / Obtenção de concentrado de alcoois graxos de cadeia longa a partir de cera de cana de açucar saponificada e acidulada
Brazil, being the world?s greatest sugarcane producer and sugar exporter, represents a potential center for the production of sugarcane wax. This wax is obtained from the filter cakes, a sub-product of the sugar and alcohol industry. From the wax, it is possible to obtain concentrates of long chain fatty alcohols and fatty acids, compounds used in several ap

8. Bromelain estraction and purification from pineapple economic viability studies / Analise de viabilidade economica de um processo de extração e purificação da bromelina do abacaxi
Brazil is one of the world?s largest producers of pineapples, its production being the third one in the world. To take advantage of the residues from fruit processing, many studies have been conducted to obtain proteolytic enzymes from them. These proteolytic enzymes are extracted mainly from fig (ficine), papaya (papain), and pineapple (bromelain). Bromelai

9. A desregulamentação e o desempenho do complexo sucroalcooleiro no Brasil.
This work analyzed the evolution of the relation between the sugar and alcohol complex and the State from 1975 to 2002, when there was a change from public intervention, marked by Proálcool, to a new situation, in which deregulation is proposed. We attempted to interpret the main political and economical stipulators of the process, as well as describe the w

10. Produção e caracterização de aromas de frutas por microrganismos pectinoliticos utilizando-se residuos agroindustriais. / Production and characterization of fruits flavor for pectinolytic microorganisms using agro-industrial residues.
Pectinases were some of the first enzymes used in commercial applications of wines and fruit juices since 1930 and their use has increased considerably, specially in food, brewery and wine, textile, pulp and paper industries. Today, these enzymes account for approximately 20% of the world enzyme market. Plants, fungi, yeasts, and bacteria naturally produce t

12. Homofermentative Lactate Production Cannot Sustain Anaerobic Growth of Engineered Saccharomyces cerevisiae: Possible Consequence of Energy-Dependent Lactate Export
Due to a growing market for the biodegradable and renewable polymer polylactic acid, the world demand for lactic acid is rapidly increasing. The tolerance of yeasts to low pH can benefit the process economy of lactic acid production by minimizing the need for neutralizing agents. Saccharomyces cerevisiae (CEN.PK background) was engineered to a homofermentati
