STUDIES ON SOIL PROTOZOA

Studies on the Metabolism of the Protozoa

A characteristic feature of euglenoid flagellates is that they synthesize granules of paramylon (paramylum) as reserve carbohydrate. We now report the results of a structural study of this polysaccharide from Astasia ocellata; a preliminary account of this work has been published (Manners, Ryley & Stark, 1964). Ast8ia ocellata is a freshwater flagellate (Class Euglenineae), being a nonphotosynt...

Studies on Growth Acceleration in Protozoa and Yeast

Studies on protozoa in ancient remains - A Review

Paleoparasitological research has made important contributions to the understanding of parasite evolution and ecology. Although parasitic protozoa exhibit a worldwide distribution, recovering these organisms from an archaeological context is still exceptional and relies on the availability and distribution of evidence, the ecology of infectious diseases and adequate detection techniques. Here, ...

Effects of altered temperature and precipitation on desert protozoa associated with biological soil crusts.

Biological soil crusts are diverse assemblages of bacteria, cyanobacteria, algae, fungi, lichens, and mosses that cover much of arid land soils. The objective of this study was to quantify protozoa associated with biological soil crusts and test the response of protozoa to increased temperature and precipitation as is predicted by some global climate models. Protozoa were more abundant when ass...

Radium and radon exhalation studies of soil

Background: Everyone is exposed to radon because it is present everywhere with varying concentrations. Radon and its progeny are well established as lung carcinogenic. Materials and Methods: Track etch technique using LR-115 plastic track detectors has been used to measure the effective radium content and radon exhalation rates in soil samples collected from urban area of Etah district...
