Abstract
The present study deals with the antibacterial activity of six marine algae collected from coastal village of Koothankuzhi in low water of spring tides. These algae were tested in six human pathogenic bacteria. The invitro antibacterial activity was performed using disc diffusion method. The maximum inhibitory activities were observed in methanol and toluene extracts whereas less response observed in aqueous extract. Methanol extract of the Amphiroa anceps and Gracillaria pygmaea showed maximum inhibitory zones when compared to the remaining seaweed extracts. The results obtained in the present study suggest that seaweeds could be used in treating diseases caused by the test organisms.
Key words: Seaweed, extracts, antibacterial activity, disc diffusion method
Abstract
Municipal solid waste (MSW) possesses a serious vicinity problem in Tamil Nadu. Studies were performed to assess the present status of municipal solid waste in Virudhunagar town. Solid waste management is a bio-science associated with the management of generation, storage, collection, transportation, processing, recycling and disposal of solid waste using the best ideas and practices of public health and other environmental conditions.
Keywords: Municipal solid waste, Virudhunagar
Abstract
The preliminary investigation of antibacterial activity of different parts in Manihot esculenta results showed remarkable activity against both gram positive and gram negative organisms. The antibacterial activity of seed extract showed positive response in all the four experimental solvents against B. subtilis. Moreover, S. aureus and K. pneumoniae encompassed poor activity on the solvents of ethanolic and aqueous extracts. While, the mixture of seed extract with chloroform, ethanol as well as aqueous extract also exposed the appreciable antibacterial activity against K. pneumoniae. Among the three parts, leaf possessed more potent antibacterial bioactivity with ethanol solvents than the remaining two parts with its respective extracts. Maximum amount of crude and fiber protein present only in seed followed by leaf and flower. In addition maximum and minimum amount of minerals such as K, Na, P and Mn noted on seed followed by leaf and flower. However, least proportion of this minerals present in stalk portion so the bioactivity was lesser when compare with other parts of this experimental plant. From the result sought to explain the use of four different parts of the Cassava plant possessed the compounds may reduce the potential growth and propagation of some gram positive and negative bacterial organisms.

Abstract
The present study highlights the medico-potentiality of 35-plant species belonging to 26-families and 34 genera were collected from the campus and these are commonly used for various ailments like skin diseases, diabetic, cuts and wounds, cough and cold, rheumatism, stomach problems etc. For each species the botanical name, family, parts used and mode of administration are provided. Our research sheds light on traditional cultures and believes towards interesting clues for further phytochemical and pharmacological research on lesser known plant sources of Western Ghats.
