The aim of the present research work to investigate antimicrobial activity of some honey samples six winter honeys six summer honeys collected from different regions of Western Ghats. The microbes used in this study are Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis. Antibacterial activity of the honeys was assayed using the Disc diffusion method. Noticeable variations in the antibacterial activity of the different honey samples were observed. Among the microbes Staphylococcus aureus is the most sensitive against all honey samples shows the maximum inhibitor zone compare to summer honeys.
The Neyveli lignite is one of the largest brown coal field of India, Cuddalore district of Tamil Nadu. The lignite is one of tertiary formation found in the Neyveli. So far many mega and micro fossils reported from this formation. The Neyveli lignite well preserved and recognizable entities are mainly woody and non-woody tissues of different angiosperm plants, spore and pollen, cuticles of leaves, resins, fungal spores and fungal fruiting bodies. The present study is about the charcoalified angiospermic wood is identified as Hopenium pondicherriensis (Dipterocarpaceae). This is a first report of Hopenium pondicherriensis from the Neyveli formation.
