Aspartate transcarbamylase from Bacillus subtilis has been purified to apparent homogeneity. A subunit molecular weight of 33,500 +/- 1,000 was obtained from electrophoresis in polyarcylamide gels containing sodium dodecyl sulfate and from sedimentat

The first action reduced iron method for nitrogen in fertilizers specifies the use of electrolytic iron and indicates that a large excess of iron is required for the reduction of nitrates. Iron reduced by hydrogen, however, is a more efficient reduct

Further study of the Raney catalyst powder method for the determination of nitrogen in fertilizers established conditions in which the commercial alloy containing 50% Ni and 50% Al was a more efficient reductant for nitrates than an experimental allo
