Abstract
A simple titrimetric assay with soybean lecithin has been used for screening phospholipase D activity from some plant sources, viz. peanut, wheat germ, cabbage and carrot. The enzyme from peanut has been purified by binding to alginate which is a water soluble polymer. The purification consisted of co-precipitation of enzyme with alginate upon addition of 0.06 M Ca++. The enzyme was eluted from the polymer using 0.2 M sodium chloride. The activity recovery was 61% with 34 fold purification.
