  • Title: Rhizobium leguminosarum biovar viciae symbiotic hydrogenase activity and processing are limited by the level of nickel in agricultural soils.
    Author: Ureta AC, Imperial J, Ruiz-Argüeso T, Palacios JM.
    Journal: Appl Environ Microbiol; 2005 Nov; 71(11):7603-6. PubMed ID: 16269813.
    Abstract:
    Analysis of levels of hydrogenase processing and activity in Rhizobium leguminosarum biovar viciae bacteroids from pea (Pisum sativum) plants showed that the oxidation of nitrogenase-evolved hydrogen is limited by the availability of nickel in agricultural soils. This limitation was overcome by using an inoculant strain engineered for higher hydrogenase expression.
