Fungitoxicity of Pollen Grains with Special Reference to Xanthium Strumarium (Compositae)

Abstract: During screening of pollen suspensions of 20 species of higher plants against Colletotrichum capsici, Curvularia lunata and Helminthosporium oryzae, only grains of Xanthium strumarium L. inhibited their spore germination completely. Its toxicity did not alter at high temperatures and during autoclaving. However, toxicity was increased when the suspensions stored for 48 h were used. It inhibited 3 out of 11 additional fungi tested at 1: 200 (w/v) dilution during its fungitoxic spectrum.

Effects of Euphorbia tirucalli latex on blood calcium and phosphate of the freshwater air-breathing catfish Heteropneustes fossilis

Abstract: The effects of Euphorbia tirucalli latex on blood calcium and phosphate of Heteropneustes fossilis was investigated in this study. The fish were subjected to 0.8 of 96-h LC50 value of E. tirucalli latex (1.05 µL L−1) for 96-h in a short-term experiment and 0.2 of 96-h LC50 value (0.263 µL L−1) for 28 days in a long-term experiment. Fish were sacrificed after 24, 48, 72, and 96 h in the short-term experiment and after 7, 14, 21, and 28 days in the long-term experiment and blood samples were analyzed for calcium and inorganic phosphate. Acute exposure of E. tirucalli latex caused a progressive decrease in the calcium level after 48 h which persists till the close of the experiment. Phosphate levels remain unaffected till 48 h but after 72 h the levels exhibit a progressive decrease. Chronic E. tirucalli latex treatment provokes a decrease in calcium levels at day 7 continuing till the end of the experiment (28 days). The phosphate levels remain unaffected up to day 7, thereafter, levels decrease from 14 day...

Luffa aegyptiaca (Gourd) Fruit Juice as a Source of Peroxidase

Abstract: Peroxidases have turned out to be potential biocatalyst for a variety of organic reactions. The research work reported in this communication was done with the objective of finding a convenient rich source of peroxidase which could be used as a biocatalyst for organic synthetic reactions. The studies made have shown that Luffa aegyptiaca (gourd) fruit juice contains peroxidase activity of the order of 180 enzyme unit/mL. The Km values of this peroxidase for the substrates guaiacol and hydrogen peroxide were 2.0 and 0.2 mM, respectively. The pH and temperature optima were 6.5 and 60°C, respectively. Like other peroxidases, it followed double displacement type mechanism. Sodium azide inhibited the enzyme competitively with Ki value of 3.35 mM.
