(Universidade Federal de São Carlos, 2012-05-17)
Pilosocereus machrisii is a columnar cacti with natural fragmented distribution; restrict to campos rupestres vegetation patches or rocky outcrops on the Cerrado domain; in Central and eastern Brazil. These features makes ...
Construção e caracterização de uma enzima quimérica obtida pela fusão gênica endoglucanase-xilanase de Trichoderma harzianum
(Universidade Federal de São Carlos, 2013-02-05)
The sugarcane bagasse is a lignocellulosic material that can be converted into ethanol by action of cellulases and xylanases. These enzymes act synergistically to convert cellulose and hemicellulose into glucose. In order ...
Associação entre polimorfismos no gene da glicoproteína-P (PgP) e resistência múltipla a anti-helmínticos em Haemonchus contortus e identificação de fatores de risco relacionados
(Universidade Federal de São Carlos, 2014-02-28)
Among the sheep parasites, Haemonchus contortus is the most prevalent and pathogenic nematode in tropical areas, causing huge economic losses. Alterations in the gene encoding the membrane P-glycoprotein (PgP) have been ...
Evolução cromossômica em Osteoglossiformes (Teleostei, Osteoglossomorpha) : uma abordagem intercontinental na família Notopteridae
(Universidade Federal de São Carlos, 2018-02-23)
The order Osteoglossiformes represent one of the most basal groups among the Teleosteos. These fishes live exclusively on freshwater environments and are characterized by the presence of a bonytongue. The group is a good ...
