Cellular and Subcellular Localization of Peroxidase Isoenzymes in Plants and Cell Suspension Cultures from Lupinus polyphyllus
1989
Abstract , leaf protoplasts and cell suspension cultures of Lupinus polyphyllus and isolated vacuoles were studied for cellular and subcellular localization of peroxidase isoenzymes. Isoelectric focusing revealed 16 peroxidase isoenzymes. The basic peroxidase isoenzymes are predominantly localized in the vacuole and, to a minor degree, unbound in the intercellular space. The acidic isoenzymes are cell wall-bound in plants and not detectable in suspension-cultured cells. Large amounts (up to 11.0 U/ml) of a single basic isoenzyme are detectable in the spent medium of cell suspension cultures.
Kinetics of solid-state fermentation of lupin with Rhizophus oligosporus based on nitrogen compounds balance
2021
Solid-state fermentation could be a potentially effective method for improving the nutritional value of legumes. The objective of this study was to explore this technology in Lupinus mutabilis, a species of lupin, using a strain of Rhizopus oligosporus mold for solid-state fermentation. Three L. mutabilis varieties (INIAP-450, INIAP-451, and Criollo) were evaluated, including the effect of the grain status (whole or ground) and integument or husk (presence or absence). Kinetic parameters of the fermentation process were studied to define the specific speed of nitrogen formation and the digestibility and nutritional quality of the resulting protein. After incubation at 28 °C for 96 h, the ti…
The effect of Pediococcus acidilactici and Lactobacillus sakei on biogenic amines formation and free amino acid profile in different lupin during fer…

Abstract The effect of Pediococcus acidilactici and Lactobacillus sakei strains on biogenic amines (BAs) formation during submerged and solid state fermentation of Lupinus luteus and Lupinus angustifolius was analysed. The composition of lupin seeds was evaluated and the influence of fermentation on free amino acid (FAA) profile was investigated. The highest protein and carbohydrate contents were found in L. luteus var. ‘Vilciai’, the highest carbohydrate contents – in L. angustifolius hybrid lines No. 1701 and No. 1800, and fat – in L. angustifolius hybrid lines No. 1700, No. 1703 and No. 1734. The interaction between the fermentation method, the bacterial strains used and lupin varieties …
