“…45 FTIR is a powerful technique for the determination of the conformational changes of proteins in interaction with surfaces. One consequence can be that they keep their conformational structure even under lack of water.…”

“…FTIR spectroscopy analysis revealed that the adsorption of ovPrP on montmorillonite induced an increase in ␤-structures and a loss in ␣-helices at pHs higher than 4.0 [10]. However, reduced amounts of ␤-sheet structures were observed for the adsorption of ␣-chymotrypsin on montmorillonite as the result of water diffusion inside the protein [11].…”

“…They act on specific substrates, transforming them into products necessary for biological cycles, and participate in many edaphic processes such as organic residue decomposition, humic substance synthesis, nitrification, oxidation, xenobiotic degradation and nitrogen fixation, among others and organo-mineral complexes (Joinville et al, 2004). Depending on the components of the soil solid phase, this interaction is caused by mechanisms that include microencapsulation, transversal bonds, copolymer formation, adsorption, capture, ion exchange and covalent bonds (Dick & Tabatabai, 1992 (Okur et al, 2009).…”

Enzymes are proteins that catalyze chemical reactions in living systems, transforming specific substrates into the products needed in biological cycles and for many edaphic processes. Soil enzymatic activities have been proposed as soil quality indicators, due to their relation with soil biology. Although the long-term effects of organic and mineral fertilization on physical and chemical soil properties have been previously studied, little is known about their effects on microbial community structure, microbial biomass carbon, microbial activity and enzymatic activity. Some studies report that organic and mineral fertilizers can affect, be it positively or negatively, microbial biomass size as well as soil microbial activity. This work examines the effect of fertilization on the enzymatic activity of soil hydrolases. Keywords: hydrolases, mineral fertilizers, organic fertilizers, soilEnzimas hidrolíticas do solo e sua resposta à adubação: uma breve revisão ResumoEnzimas são proteínas que catalisam reações químicas em sistemas vivos, transformando substratos específicos para os produtos necessários em ciclos biológicos e para muitos processos edáficos. Atividades enzimáticas do solo têm sido propostos como indicadores de qualidade do solo, devido à sua relação com a biologia do solo. Embora os efeitos a longo prazo da adubação orgânica e mineral sobre as propriedades físicas e químicas do solo, foram previamente estudados, pouco se sabe sobre os seus efeitos sobre a estrutura microbiana, o carbono da biomassa microbiana, atividade microbiana e atividade enzimática. Alguns estudos relatam que os fertilizantes orgânicos e minerais pode afetar, seja ela positiva ou negativamente, o tamanho da biomassa microbiana, bem como a atividade microbiana do solo. Este trabalho examina o efeito da adubação sobre a actividade hidrolítica enzimática de solo.
