Isolation and Characterisation of Oleginous Microalgal Isolate Using FT-IR Spectroscopy
Authors : G. Vidyadharani ,R. Dhandapani ,

Microalgae biodiesel can be a suitable alternative for fossil fuel in future. They are considered as better third generation biodiesel feed stock and can adapt in wide variety of environ-ment and adverse environment such as domestic and industrial effluents. Hence selection of oleagi-nous microalgae based on native biomass and lipid production is an important step. In this study Chlorella sp...

Authors : K. M. Prabu ,K. Suguna ,P. M. Anbarasan ,T. Selvankumar ,V. Aroulmoji ,

Hazardous chemicals escape into the environment due to many natural and manmade activities. They cause adverse effects on human health and environment. Natural dye-sensitized solar cells (NDSSCs) have gained considerable attention in the field of solar energy due to their simple fabrication, good efficiency, and low production cost. Natural dyes are environmentally and economically superior to...

Isolation and Identification of Protease Producing Halophilic Bacteria
Authors : M. Vikramathithan ,R. Dhandapani ,

The protease producing halophilic bacteria were isolated from the banks of different regions of the Indian Ocean near Chennai. In the preliminary screening twelve halophilic bacterial isolates exhibited protease production. Protease enzyme was produced and its activity was assessed through Kunitz assay method. Among them one isolate was taken and identified by Bergey's manual of systemic...

In vitro callus induction and plantlets regeneration from leaf explants of Plectranthus barbatus Andrews - a valuable medicinal plant
Authors : P. Thangavel ,S. John Britto ,S. Prabhu ,S. Senthil Kumar ,

An efficient shoot regeneration protocol based on callus induction and multiple shoot development has been standardized for Plectranthus barbatus. The leaf explants were cultured on Murashige and Skoog (MS) [1] medium supplemented with α-naphthalene acetic acid (NAA at 2.68 - 16.11 μM) alone or in combination with Kinetin (KIN) and 6-benzyladenine (BA) for callus induction. The best...
