Antimicrobial activities of certain seaweeds from muddy shore places of kerala

A study was carried out to reveal the growth inhibitory effect of methanol crude extract (MCE) and methanol supernatant extract (MSE) of sea weeds: 1) Gracillaria corticata, 2) Hypnea musciforms, 3) Gelidium micropterum and 4) Hypnea valentiae against six bacterial pathogens, 1) Pseudomonas aeruginosa, 2) Bacillus licheniformis, 3) Serratia marcescens, 4) Aeromonas hydrophila, 5) Acinetobacter baumanii, 6) Escherichia coli and two fungal strains, 1) Aspergillus niger and 2) Candida albicans respectively. Well diffusion method using zone of inhibition as indicator for growth inhibition was adopted. The results showed that methanol extracts of seaweeds viz., Gracillaria corticata, Hypnea musciforms, and Hypnea valentiae prevented the growth of pathogenic bacteria and fungi. The effect on growth was observed as zone of inhibition, the diameter of which was indicated in the units of a millimeter. The growth of the bacterium, Serratia marcescens was affected by methanol supernatant extract of the three types of seaweeds, Gracillaria corticata, Hypnea musciforms, and Hypnea valentiae, and by the methanolic crude extract of Hypnea musciforms and Hypnea valentiae. However, the growths of other species of bacteria were not controlled by either of the extracts of the seaweeds except, Bacillus licheniformis which was controlled by only Gracillaria corticata. The growth of fungi: Aspergillus niger and Candida albicans were inhibited by the methanol extracts of Gracillaria corticata. Between the two forms of methanolic extracts i.e., supernatant and crude, the efficiency of the supernatant extract was greater than that of crude one. Further, among the three types of seaweeds which showed an effect on the growth of microbes, the level of the zone of inhibition caused by Gracillaria corticata was statistically higher than that of the other two, Hypnea musciforms, and Hypnea valentiae.

Fabrication of potable and eco-friendly solar disinfection (sodis) unit and its performance analysis

Solar disinfection (SODIS) is a technique, which involves utilization of solar energy to make safe drinking water from biologically contaminated water. In the conventional SODIS method, the PET bottles are filled with polluted water and exposed to the sunlight for a certain period depending upon the local weather conditions. However much more effective disinfection system is needed to overcome the problems of inefficient utilization of available solar energy and the health risk posed by treating the water using chemicals during the purification process. Hence, the present work aims in designing a portable solar disinfection unit that can efficiently use solar energy by manually adjusting the unit according to sunlight availability. Along with it, incorporation of the additional eco-friendly unit with water purifying plants Vetiveria zizanioides (Vetiver) and Hemidesmus indicus (Nannari) is done to achieve high efficiency in producing potable water from biologically contaminated water. The contaminated water samples treated in the solar disinfection unit and eco-friendly water purifying unit are analyzed for the presence of total coliforms and E-coli by using the Most probable Number method and P/A analysis, respectively. A reduction in 99.74% of total coliform count and absence of E-coli was observed in the treated water samples. The physicochemical analysis was carried out to ensure the suitability of treated water for consumption and the results revealed a notable reduction in the parameters, and all the parameters came under the permissible range of IS drinking water characteristics. The designed system can be used to disinfect the contaminated water sample most efficiently, thereby making the water suitable for consumption.
