(Universidade Católica de Pernambuco, 2014-03-14)
Activities of oil refineries and accidental spills with oil and derivatives release in
the environment highly toxic hydrocarbons, that represent a great danger,
especially for communities near of the contaminated site. ...
Produção de biossurfactante por Bacillus subtilis UCP 0999 em sbstratos não convencionais e de baixo custo
(Universidade Católica de Pernambuco, 2009-01-24)
The biosurfactants biopolymers are used in various industrial sectors, but still, are not economically competitive with synthetic surfactants, due to high production costs, where the substrate is 30% of the final costs. ...
Otimização de processo de biodegradação de óleo diesel por Candida lipolytica UCP 0988 em água do mar
(Universidade Católica de Pernambuco, 2018-12-12)
Response surface methodology was used to model the concentration of biomass in the process of diesel oil biodegradation in sea water by Candida lipolytica CPU 0988. The seawater was collected from beach near Suape's ...
Redes neurais artificiais como ferramenta de apoio ao desenvolvimento de meios de produção de biossurfactantes
(Universidade Católica de Pernambuco, 2009-08-24)
Artificial neural networks were used to model biosurfactant production process by Candida lipolytica UCP 0988, using diesel oil as carbon source. The modeling was carried out using data of 24 full factorial design composed ...
