    O cultivo do trigo no Brasil tem sido acometido por danos significativos devido à brusone, doença causada pelo fungo Pyricularia oryzae Cavara

    Nutrição saudável: a relação entre a oferta equilibrada de nutrientes minerais às plantas de trigo e a ocorrência de doenças bióticas na cultura.

    Treze elementos minerais são considerados essenciais para o crescimento e desenvolvimento das plantas de trigo: nitrogênio (N), fósforo (P), potássio (K), cálcio (Ca), magnésio (Mg), enxofre (S), manganês (Mn), zinco (Zn), cobre (Cu), boro (B), ferro (Fe), molibdênio (Mo) e cloro (Cl). Esses nutrientes são os mesmos que são essenciais para a grande maioria das plantas de importância agrícola, e a sua oferta para as plantas, em proporções equilibradas, é fundamental para o sucesso da produção e da qualidade tecnológica dessa produção que, no caso da cultura do trigo, são os grãos.bitstream/item/223979/1/Trigo-nutricao-saudavel.pd

    Extraction and purification of phycobiliproteins from algae and their applications

    Get PDF
    Microalgae, macroalgae and cyanobacteria are photosynthetic microorganisms, prokaryotic or eukaryotic, living in saline or freshwater environments. These have been recognized as valuable carbon sources, able to be used for food, feed, chemicals, and biopharmaceuticals. From the range of valuable compounds produced by these cells, some of the most interesting are the pigments, including chlorophylls, carotenoids, and phycobiliproteins. Phycobiliproteins are photosynthetic light-harvesting and water-soluble proteins. In this work, the downstream processes being applied to recover fluorescent proteins from marine and freshwater biomass are reviewed. The various types of biomasses, namely macroalgae, microalgae, and cyanobacteria, are highlighted and the solvents and techniques applied in the extraction and purification of the fluorescent proteins, as well as their main applications while being fluorescent/luminescent are discussed. In the end, a critical perspective on how the phycobiliproteins business may benefit from the development of cost-effective downstream processes and their integration with the final application demands, namely regarding their stability, will be provided.publishe
