Epiphytic phytoplankton in response to divergent air pollutants from urban and commercial zones of Chennai District, Tamil Nadu, India: A case study towards phytoplankton based Air Quality Index.

Microalgae are an effective source of bioindicators to screen any changes of the natural ecosystem in the environment. With the increase in air pollution due to different potential sources, pollution monitoring stations are deployed across the nation with sophisticated analytical methodologies. However, phytoplankton can also serve as an indicator of air pollution as they possess the ability to absorb particulate contaminants.

Bioactive potential and composition analysis of sulfated polysaccharide from Acanthophora spicifera (Vahl) Borgeson.

Marine seaweeds contain a valuable source of functional bioactive polysaccharide and it plays main role for effective anticancer activity. The structural feature of SPs was studied through FT-IR and H NMR spectra analysis. The isolated SPs from A.

Antibacterial cysteine protease from Cissus quadrangularis L.

An antibacterial Cp was extracted from the stem of Cissus quadrangularis and purified with a 5.39 fold increase in specific activity and 8.67% recovery.

Synthesis and antioxidant properties of enone core based dendrimers with carbazole as surface group.

Synthesis of enone core based dendrimers with carbazole as surface group has been achieved. All the synthesized dendrimers showed excellent antioxidant behavior with commercially available 1,1-diphenyl-2-picryl hydrazyl (DPPH).

Synthesis and antibacterial activity of some novel imidazole-based dicationic quinolinophanes.

Synthesis of novel quinoline based dicationic benzimidazolophanes and imidazolophanes incorporating various spacer units is described. Some of the quinolinophanes 1b, 3a,3b and 4a exhibit good antibacterial activity against most of the human pathogenic bacteria in the tested concentrations as compared to the other cyclophanes as well as the test control, streptomycin.
