Obtenção e aplicação biológica de quitinases recombinantes da formiga cortadeira Atta sexdens
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 21/08/2023)Chitinases catalyze the cleavage of the β-1,4 bond of chitin, a polysaccharide produced by several organisms including insects. From a biotechnological point of view, these enzymes have potential application in the ... -
Obtenção e caracterização de uma lacase amarela recombinante de Leucoagaricus gongylophorus
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 26/04/2018)Laccases are enzymes that have a wide range of applications including their use in bioremediation. These enzymes have been described as multi copper oxidases that reduce oxygen to water while oxidizing compounds. Some ... -
Estudos da expressão e da função do gene sintase de quitina em Atta sexdens
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 06/04/2018)In Brazil, leaf-cutting ants belonging to the genus Atta and Acromyrmex and are considered as pests in agricultural and forestry regions that can lead to great economic losses. The aim of this work was to identify the ... -
Isolamento e caracterização de enzimas ligninolíticas expressas pelos fungos Chaetomium cupreum URM 5066 e Mucor racemosus CBMAI 847
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 25/05/2018)The degradation of lignin, which together with cellulose and hemicellulose constitutes the cell wall of plants, is generally hampered by its complex structure, its high molecular weight and its insolubility. However, fungi ... -
Produção, caracterização e aplicação biotecnológica de lacases do fungo Leucoagaricus gongylophorus
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 08/12/2015)Interest in the study of Leucoagaricus gongylophorus fungus arises principally from the symbiotic relationship that it maintains with cutting ants from Atta and Acomyrmex genres that are considered important agricultural ... -
Estudos bioquímicos e cinéticos de acetilcolinesterases de formigas cortadeiras (Atta sexdens)
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 29/09/2017)Acetylcholinesterase (AChE) (EC 3.1.1.7) is the enzyme responsible for catalyzing the hydrolysis of the neurotransmitter acetylcholine leading to the release of acetate and choline. In insects, acetylcholine is one of the ... -
Avaliação do potencial biotecnológico de celulases do fungo Lasiodiplodia theobromae na hidrólise de tecido de algodão
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 28/08/2023)The textile industry generates millions of tons of waste that are discarded and take about 20 years to be degraded in nature. The enzymatic hydrolysis of tissues has been shown to be a good alternative for recycling these ...
