• Dental plaque is the community of microorganisms found on a tooth surface as a biofilm, embedded in a matrix of polymers of host and bacterial origin. Over 400 microbial
    species can be found in the typical adolescent human mouth. The most virulent of these species is Streptococcus mutans, which has been found to be the initiator of most dental caries. As a result, dental caries can be considered one of the most widespread and common infectious disease.

  • Scientific understanding of probiotics and their potential for preventing and treating health conditions is at an early stage. Probiotics is rapidly gaining importance in medical science and food science. We created a review of literature on various aspects of probiotics including mechanism of action, health benefits, side effect, stability and antimicrobial activity.

  • The requirement of energy in India has been growing exponentially over the years. Since conventional energy options are futile to tackle this raise, the needs for non-conventional energy sources have become essential. Solar Photovoltaic cell could be one such alternative energy source since solar energy is available abundantly in the world which is renewable, eco friendly and free from pollution.

  • Klebsiella pneumonia is an opportunistic human pathogen that can cause acute ,life threatening infections.Part of the virulence repertoire of this microorganism includes the ability to sequeater iron from the host during infection by synthesis and secretion of siderophores..The aim of study was to determine the effect of Petroleum ether, chloroform, methanol and water extracts of eight traditional Indian medicinal plants Biophytum sensitivum, Leucus aspera, Aegle marmlos, Plectranthus amboini

  • Mangroves have enormous ecological value. They protect and stabilize coastlines, enrich coastal waters, yield commercial forest products and support coastal fisheries. Mangroves are among the world’s most productive ecosystems, producing organic carbon well in excess of the ecosystem requirements and contributing significantly to the global carbon cycle. Extracts from mangroves and mangrove dependent species have proven activity against human, animal and plant pathogens.

  • Fibronectin, an extra cellular matrix glycoprotein was purified from human plasma obtained from Regional Cancer Centre Trivandrum. Gelatin based affinity chromatography was used for the purification of the protein. The usage of pressure was found to have prominent impact in the purification of the protein by reducing albumin contamination, which we suspect would have non specifically bound to the gelatin resin. The quality of the protein purified was analysed using SDS –PAGE.

  • As the importance of blood glucose control for both diabetic and non diabetic patients continues to increase, there is a need for advanced glucose sensing technologies. The low accuracy and sensor drift become major problems with in vivo environments especially for enzyme based electrochemical glucose sensors. This study dealt with the use of E.coli as an effective biorecognition element in a whole cell based biosensor. A lac operon based sensor has been decided to develop.

  • The list of pollutants which pose environmental and health hazard are tough for biodegradation, is a long one and involves solvents, wood preservative chemicals, refrigerants, plasticizers, coal tar wastes, pesticides, biphenyls, synthetic fibers, plastics etc. The present study deals with the isolation of plastic degrading microorganisms from the plastic samples, analysis of physical or changes produced during biodegradation and the study of enzymes involved in biodegradation.

  • Peptidoglycan (PG) hydrolases or autolysins are a group of enzymes which degrades bacterial cell wall at specific sites. Staphylococcus aureus produces two major PG hydrolases: major autolysin (AtlA) and Aaa, a autolysin/adhesin protein. Amidase are surface-associated proteins that have both enzymatic and adhesive functions. AtlA is the most predominant autolysin in Staphylococcus aureus. The AltA protein only with an amidase domain and the two repeat sequences R1 and R2 is 62 kDa.

  • The current studies provided a direct illustration that electrical power can be generated economically in a two chambered microbial fuel cell. Under the anaerobic condition at the anode, the electrons released by the Proteus vulgaris are directed towards the cathodic chamber through an external circuit. Low cost and less oligodynamicity encouraged the use aluminium as anode. Anaerobic condition of the anodic chamber is achieved by using an air-tight rubber suction outer lid.

  • This project proposes to develop a cerebellum inspired pattern recognition algorithm for robotic data classification. The project aims to investigate the temporal and spatial dynamics in the cerebellar network models capable of predicting cerebellar input-output transformations by analyzing the mathematical and computational properties of the network. Both labs have been working together since 2004 on cerebellar models.

  • In contrast to other fields in biology, mathematical thinking and methodology have become entrenched in neuroscience since its very beginning, as witnessed by the classical work of Hodgkin and Huxley. One of the biggest open challenges mathematicians and engineers face is to understand the complex computation that takes place in our brain. Among the most interesting parts of the brain, is the ‘little brain’, otherwise known as the cerebellum.
