Título:  A poultry litter-derived organomineral phosphate fertilizer has higher agronomic effectiveness than conventional phosphate fertilizer applied to field-grown maize and soybean.

Conteúdo:  Inadequate disposal of poultry litter (PL) may promote eutrophication of water bodies due to its high nutrient content, including phosphorus (P). Thus, recycling P from PL to produce organomineral fertilizer (OMF), reduces the dependence on finite mineral P reserves, and also reduces P losses from soil. In this context, a field experiment was carried out to assess the agronomic effectiveness of a granular PL-derived OMF applied to maize and soybean in a highly weathered tropical soil. OMF was compared to single superphosphate (SSP) at five P rates between 0 and 70 kg ha-1. The shoot dry weight (SDW) and grain yields of soybean and maize were affected by P rates; however, no difference between OMF and SSP was found. A similar trend was observed for soil P and P uptake. The leaf P content and soil pH were not affected by either P sources or P rates. Although there was no difference between OMF and SSP on the crop yields, OMF had the highest relative agronomic effectiveness based on the SDW. These results show that the production of granular OMF from PL is a viable alternative to conventional P fertilizers and reduces the dependence of mineral P reserves.

Título:  Combination of MALDI-TOF MS and UHPLC-ESI-MS for the characterization of lytic polysaccharide monooxygenase activity.
Ano de publicação:  2020
Fonte/Imprenta:  Analytical Methods, n. 2, 2020.
Idioma:  Inglês
Conteúdo:  Lytic polysaccharide monooxygenases (LPMOs) are redox enzymes of high biotechnological interest due to their capacity to degrade recalcitrant polysaccharides, such as cellulose, by an oxidative mechanism. The characterization of LPMOs is challenging since they generate a variety of catalytic products which include native oligosaccharides (non-oxidized) and oligosaccharides oxidized at the reducing end (C1 position), the non-reducing end (C4 position), or both ends, with different degrees of polymerization. Moreover, oxidized products exist in equilibrium with their hydrated forms, which further complicates their identification. The lack of commercial analytical standards for all these possible forms of oxidized oligosaccharides and the low concentration of these products make LPMO functional characterization dependent on advanced mass spectrometry techniques capable of identifying the profile of oxidized products. Here, a new approach for the characterization of cellulose-active LPMOs based on the combination of MALDI-TOF MS and hydrophilic interaction UHPLC-ESI-MS was proposed and optimized. The LPMO TrAA9A from Trichoderma reesei was used as a model enzyme to develop and test the MS methods. MALDI-TOF MS and UHPLC-ESI-MS methods were both capable of identifying putative C1, C4 and C1/C4 oxidized cello-oligosaccharides as well as their native counterparts generated after cellulose treatment with LPMO, which allows their utilization to characterize type I (C1-oxidizer), type... Mostrar Tudo
