Histochemical Localization of Acid Phosphatase in the Haustoria of Two Stem Parasites Cassytha Filiformis L. (Lauraceae) and Cuscuta Reflexa Roxb. (Cuscutaceae)
Abstract: Abstract Acid phosphatases consist of a group of non-specific enzymes that hydrolyse a variety of organic esters with the liberation of phosphate ions. Sodium α-naphthol phosphate substrate is used to localise acid phosphatase activity. The activity of this enzyme was greatest at the sites of haustorial entry and in the region of the hausorial contact with the host vasculature. The presence of this enzyme at the region of interface indicates …

Characterization of Formed Third Phase in the Nitric Acid-30% TBP/n-Dodecane System
Abstract: In solvent extraction operations, limited solubility of extracted solvate in the organic phase results in partitioning of the later into two phases, called light organic and heavy organic phase respectively. The phenomenon is studied well and reported for tetravalent actinides in TBP systems but nitric acid third phase in TBP systems was almost neglected. In this study, nitric acid third phase was generated for TBP system and its characterization has …
