ABSTRACT: A study was conducted to explore the wild medicinal flora of Banaras Hindu University main campus, India, spreading over a land area of about 1,350 acres. A total of 177 wild medicinal plant species were collected, of which 175 were represented by the Angiosperms while 2 plant species were represented by the Pteridophytes. The Angiospermic group of wild medicinal plants was represented by 136 genera distributed among 55 families. Asteraceae, Fabaceae and Acanthaceae are the dominant families of the wild medicinal flora of Banaras Hindu University main campus.

ABSTRACT: Laboratory experiments were performed to access the effects of pH change on growth of a microalga in water soluble fractions of crude oil using Chlorella pyrenoidosa. Growth of the alga was observed in culture by estimating chlorophyll a content. The effect of varying pH on growth in water soluble fraction of crude oil on a 14 day bioassay shows no significant difference at p< 0.05 in growth of the microalga in both pH moderated and non pH moderated culture of Water Soluble Fractions (WSF) of crude oil. Maximum growth and utilization of hydrocarbon by the microalga was obtained at pH of 8.2 and the least at pH 7.5. Biomass production (chlorophyll a synthesis) by C. pyrenoidosa in continuous culture was considerably affected by the pH at which the cultures were maintained. Biomass production experiment revealed that pH values in the range of 8.2 and 8.5 synthesized more photosynthetic materials than those in 7.5 pH level. Dry weight showed higher physiological response at pH 8.5 and the least at pH 7.5. The result obtained in this study is a vital contribution in processing and cultivating of algae.
