The Vibrio alginolyticus was found to dominant group with high population density of 160±2.0×10-5 colony forming unit which has been isolated from Mandapam coast of South India. Agar well diffusion method was used to find out the inhibition of biofilm forming bacteria through zone of inhibition. Followed by the time kill assay and anti-adhesion assay was performed by exploiting the potentials of antibiofilm activity. Preliminary phyto-chemical screening shows the alkaloids and saponins were exist in the chloroform extract of Rhizophora apiculata. Further, HPLC chromatogram shows two significant major peaks with 27.943 and 98.670 retention time. HPTLC profile was recorded with Rf value concluded the broad antifouling properties of the chloroform extracts of Rhizophora apiculata inhibit the growth of pioneering marine biofouling bacteria.

Abstract: The diversity of haloalkaliphilic gammaproteobacteria from hypersaline Sambhar soda lake, India was analyzed. Four different sampling points were selected within the lake. Nine moderate and extreme isolates were identified using morphological, biochemical and 16S rRNA sequencing method. These isolates were screened for salt, pH and temperature tolerance. In the gammaproteobacteria group, all the selected isolates belonged to one genus Halomonas represented by four different species Halomonas pantelleriensis, Halomonas venusta, Halomonas alkaliphila, and Halomonas sp. All these isolates were capable to grow in 10 -20% NaCl concentrations, 8-12 pH and 20 to 50 oC temperature. These isolates were competent to produce industrially important extracellular hydrolytic enzymes. Most of them were shown to produce cellulase, pectinase and xylanase.

Abstract: Hydrobiology of Sambhar Salt Lake a Ramsar site, Rajasthan was studied with respect to their chemical composition of brine and extremely haloalkaliphililes. Chemical compositions of brine samples were analyzed. Brine had pH value of 11 and a total salt content 30% (w/v). The sodium chloride and sodium bicarbonate were principal salts of brine. Metals like Fe, Mn, Zn, Cu, As, Cr, Pb, and Cd were detected in significant amount. Total 64 morphologically distinct isolates were recovered from brine samples out of that five were confirmed as red extremely haloalkaliphilic archaeabacteria and identified by using 16S rRNA sequencing method. All five isolates were required high salt (10-30%) and alkaline pH (9-10) for their optimum growth and pigmentation.16S rRNA sequencing revealed that selected isolates were members of Natronococcus geneus.

Till date there is no report on occurrence of sea urchins from Mumbai coast. This paper reports the first record of Temnopleurus toreumaticus (Leske, 1778) from Mumbai coast. The specimen was collected from Mumbai beach and identified using standard available literature. This study is a preliminary data for further investigations, monitoring and conservation.
