Estudo químico e histoquímico das glândulas metapleural e labial de formigas cortadeiras e a influência destas nas relações simbiontes presentes nos jardins de fungo
(Universidade Federal de São Carlos, 2015-02-18)
Leaf-cutting ants are considered the most derived insects on the planet. The
performance in maintaining the aseptic conditions of the colonies is a key factor
of the ecological success of these ants. Several defenses are ...
Obtenção e caracterização bioquímica de xilanases nativas e recombinante do fungo Leucoagaricus gongylophorus
(Universidade Federal de São Carlos, 2013-08-30)
Xylanases are enzymes which randomly cleave the main chain of xylan, the most abundant non-cellulosic polysaccharide of plants cell wall. Xylanases are commonly produced by a wide range of organisms including bacteria, ...
Bioactivity, chemical and microbial diversity in Alternanthera brasiliana : the influence of endophytes on antibiotic production
(Universidade Federal de São Carlos, 2016-02-25)
Alternanthera brasiliana is a plant widely used by Brazilian people
as a folk medicine for the treatment of numerous diseases, especially
