Studies of the amidase activity ofextracts of various animal tissues have been reported in earlier papers (Bray, James, Ryman & Thorpe, 1948; Bray, James, Raffan, Ryman & Thorpe, 1949a; Bray, Thorpe & Wood, 1949c; Bray, James, Thorpe, Wasdell & Wood, 1949 b). The present paper records further observations, including the behaviour of the enzyme towards some saturated long-chain and w-phenylsubst...

It was stated in previous papers (Avis, Bergel & Bray, 1955; Avis, Bergel, Bray, James & Shooter, 1956; Avis, Bergel & Bray, 1956) that the enzymie activity of purified xanthine oxidase from cow's milk, like that of other enzymes, deteriorates in aqueous solution under a variety ofmild conditions. Since then we recorded in a preliminary communication (Bergel & Bray, 1956) the stabilizing effect...
The ability of different soil tests in predicting soil phosphorus (P) is important in soils amended with municipal sewage sludge. The objective of the present study was to evaluate several chemical extractants to estimate available P for bean growing in 10 calcareous soils amended with municipal sewage sludge from Chaharmahal-Va-Bakhtiari province under the greenhouse conditions. For this purpo...
The chemical conditions of the rhizosphere are known to considerably differ from those of the bulk soil, as a consequence of a range of processes that are induced either directly by the activity of plant roots or by the activity of rhizosphere microflora. Plant species have involved various adaptive strategies to acquire P from soil pools. Therefore, the objective of this research was to evalua...
