Occurrence of water molds in relation to hydrogen ion concentration in some lakes of Nainital, India

Abstract

26 species of water molds belonging to Blastocladiales, Saprolegniales, Lagenidiales and Peronosporales were found to be different in their pH tolerance.

Oomycetes and Chytridiomycetes (Mastigomycotina) from water bodies in Tübingen region (Germany)

“…Moreover. KHULBE (1980) found that most of water moulds are able to tolerate a wide range of pH and some of them do not tolerate pH value less than 7.5. The water temperature of the investigated samples at the time of sampling was relatively low to moderate and ranged between 11.0-25.0 ' C .…”

Species Composition and Habitat Preference of Watermolds in the Nainital District of Kumaun Himalaya, India

“…There is no general consensus among different workers about the cause of fluctuations in species content of watermolds. Different workers have attributed seasonal fluctuations to different causes such as pH (LUND 1943;WOLF and WOLF 1941;SUZUKI 1960;DAYAL and TANDON 1963;SRIVASTAVA 1967;KHULBE 1980) MER et al 1980). In the present study, fourteen species of watermolds were restricted to terrestrial and seven species to aquatic habitats while eleven species were common in both the systems.…”

Fungi from water, soil and air polluted by the industrial effluents of manquabad superphosphate factory (Assiut, Egypt)

“…Also, SUZUKI (1961) indicated that zoosporic fungi were very scarce or absent in acidotrophic lakes (pH 1.90 -2.75) and in pH 2.9 -5.8 one or more fungi were recovered. KHULBE (1980) classified water moulds into three groups: with a wide range of pH tolerance (7.3-8.8), with a moderate range (7.4-8.2) and with a narrow range of pH tolerance (7.3 -7.7). DAYAL and TANDON (1963) found a maximum number of water moulds in a pond having pH 6.9 -7.0.…”
