Esterase Activities

Since data on esterase content of intact dormant spores are meager, a study was carried out with various enzyme substrates and several methods of product detection on intact and ruptured preparations of Bacillus coagulans. Measurement of hydrolysis of triacetin, naphthyl acetates, fluorescein diacetate, ethyl acetate, and ethyl butyrate demonstrated the presence of arylesterase, carboxylesterase, acetyl esterase, and lipase activities in both the intact and ruptured preparations of the non-germinated organism used. It was observed that spore esterase was inhibited by normal and basic copper acetate, eserine, taurocholate, 253.7 mμ ultraviolet light, and temperatures between 50 and 100 °C.

In order to study the retention of copper in cirrhotic liver, rats were made cirrhotic by carbon tetrachloride inhalation twice weekly for three months and fed 0.2% copper acetate ad libidum in drinking water for one month. The liver tissue was fixed in osmium, sectioned approximately 2000 Å thick, and stained with lead citrate. The section was examined in a scanning electron microscope (JEOLCO JSM-2) in the transmission electron mode.Figure 1 shows a typical area that includes a red blood cell in a sinusoid, a disse, and a portion of the cytoplasm of a hepatocyte which contains several mitochondria, peribiliary dense bodies, glycogen granules, and endoplasmic reticulum.

Lc50 Value

Study to assess the larvicidal property of Lantana camara leaves against Aedes triseriatus larvae found that the ethyl acetate extract had profound larvicidal action with the crude extract having a LC50 value of 409.831ppm. GC-MS analysis of the ethyl acetate extract confirmed the presence of twenty-one compounds out of which beta-caryophyllene covered the highest percentage of the chromatogram area. Further tests with beta-caryophyllene against the mosquito larvae proved it to be the active ingredient of L. Camara with a LC50 value of 104.243ppm.
