Although seeds of other Canavalia species, like jackbeans (Canavalia ensiformis), are commercially grown, the species Canavalia grandiflora Benth. is not grown commercially and occurs only in the wild in the state of Ceara, Brazil. Canavalia plants are used for animal fodder, although they contain some antinutritional factors, such as the non-proteic amino acid canavanin, trypsin inhibitors, canatoxin, and lectins. The seeds are used as potential sources of the urease enzyme, and also of concanavalin A, a lectin with many biotechnological applications, such as chromatography for glicoconjugate purification. The whole jackbean plant is largely used to improve soil fertility.
