Bioprospecção de fungos filamentosos endofíticos de espécies medicinais com potencial de produzir moléculas de interesse biotecnológico
(Universidade Federal de São Carlos, 2018-03-09)
Endophytic microorganisms are defined as organisms that live inside plant tissues without
causing any damage to the host plant. Bacteria and fungi produce several bioactive
compounds, with antimicrobial, enzymatic, ...
Comparação do desempenho de diferentes estratégias de montagem do genoma de Bertholletia excelsa Bonpl. (Lecythidaceae)
(Universidade Federal de São Carlos, 2020-03-06)
The Brazil Nut (Bertholletia excelsa) is an arboreal species, native to the Amazon forest, by which there’s a concern referring to its ecological sustainability. Therefore, sequencing and assembling the genome might ...
Efeitos da combinação de agrotóxicos e do patógeno Nosema ceranae no desenvolvimento de Apis mellifera africanizada
(Universidade Federal de São Carlos, 2020-03-03)
Bee populations have declined in several parts of the world, possibly due to a combination of biotic and abiotic factors, such as pesticides, pathogens and forest fragmentation. Since the larval stage, bees are exposed to ...
Compósitos de alginato como material inteligente, modulação de solubilidade e objeto de ensino
(Universidade Federal de São Carlos, 2019-11-06)
Alginate is a nontoxic, biocompatible polymer, that is easily obtainable. It can form gels through crosslinking when in contact with bivalent metal ions (ionic alginate gel) or through intermolecular bonds by exposure to ...
Ação do mercúrio no Sistema Hepatonefrocítico de operárias de Bombus atratus (Hymenoptera: Bombini)
(Universidade Federal de São Carlos, 2020-06-30)
In addition to environmental stressors, native Brazilian bees are continuously exposed to biotic stressors, such as parasites and pathogens, and abiotic stressors, such as pesticides and metals. Metallic contaminants such ...
Padronização e aplicação do ensaio cometa para análise de genotoxicidade do mercúrio em abelhas da espécie Bombus atratus (Hymenoptera, Bombini)
(Universidade Federal de São Carlos, 2020-03-03)
The mercury (Hg) is a non-essential trace metal, that is highly toxic to living beings, is a major contaminant of water bodies. Despite the genotoxic importance of Hg, there are no studies on its genotoxicity in native ...
