Microbial conversion of crude and purified glycerol obtained in the process of biorefining Crotalaria juncea is carried out to produce succinic acid using Escherichia coli. Batch tests are performed for nine different substrate concentrations of commercial, purified and crude glycerol, in order to observe cell growth and substrate utilization rate. Inhibitory (Halden-Andrew, Aiba-Edward, Tessie...

Abstract Purpose Hyperaccumulators are plants with the ability to tolerate and accumulate high concentrations of potentially phytotoxic metals. The Australian legume Crotalaria novae-hollandiae accumulates remarkably zinc (Zn), cadmium (Cd) copper (Cu) in its shoots when growing on metalliferous (Zn-Cd ‘calamine’) soils. This study aimed investigate zinc-cadmium tolerance C. compare it closely ...

Tropical soils have chemical characteristics that promote a fixation of the P element, making phosphate fertilizers in these low efficiency. The present work aimed to evaluate efficiency fertilization corn crop different systems, sources and mixture between sources. It was adopted completely randomized design with subdivided plots. plots were formed by three treatments (system cultivation corn)...

Five different species of Crotalaria were analysed for their proximate and mineral composition, protein fractions, amino acid profile of total seed proteins, fatty acid profile of seed lipids, in vitro protein digestibility vitamins (niacin and ascorbic acid) and certain anti-nutritional factors. The major findings of the study were as follows: crude protein content ranged from 12.50 27.12%, cr...

The interaction of glycoproteins of rough and smooth microsomal and Golgi membranes with Sepharose-bound lectins has been studied. One of these lectins was a crude preparation from wheat germ lipase which was found to bind primarily to N-acetyl neuraminic acid. Rough microsomes, smooth microsomes and Golgi membranes contain glycoproteins which bind to Concanavalin A (Con A specific for mannose ...

Se pretendió obtener información del efecto de plantas cobertura, sobre la producción mandioca, en plantío directo, suelo francoarenoso Itapúa, Paraguay, junio 2018 a 2021. Fue utilizado un diseño bloques completamente al azar, con seis tratamientos y cuatro repeticiones. Los consistieron rotación T1 (avena negra) + (maíz +mucuna ceniza), T2 (lupino blanco) dolichos), T3 (nabo forrajero) Cajanu...

O objetivo desse trabalho foi avaliar os efeitos de extratos produzidos com diferentes partes Crotalaria e Milheto em concentrações, na germinação crescimento plântulas tomate. Para elaboração dos foram utilizadas: raízes, folhas inflorescências, separadamente. As concentrações utilizadas foram: 0, 25, 50 100%. variáveis analisadas (porcentagem índice velocidade), comprimento massa seca (raízes...
