C-phycoerythrin was isolated and purified from marine Pseudanabaena sp. using two step chromatographic methods. Phycobiliproteins in the marine Pseudanabaena was extracted in 100mM phosphate buffer (pH 7.2) and precipitated by salting out. The precipitated C-phycoerythrin was purified by gel...

Polyhydroxyalkanoates are water-insoluble, hydrophobic polymers and can be degraded by microorganisms that produce extracellular PHA depolymerase. The present work was aimed to evaluate the degradability of Polyhydroxyalkanoate film produced by Halomonas hydrothermalis using Jatropha biodiesel...

Two chromogenic complexes, L.Zn (where L is (E)-4-((4-(1,4,8,11-tetraazacyclotetradecan-1-ylsulfonyl)phenyl)diazenyl)-N,N-dimethylaniline) and its [2]pseudorotaxane form (α-CD.L.Zn), were found to bind preferentially to adenosine triphosphate (ATP), among all other common anions and biologically...

PHAs are biodegradable and environmentally friendly thermoplastics. The major contributor to PHA production cost is carbon substrate cost, therefore it is desirable to produce PHA from waste/byproducts like Jatropha biodiesel byproduct. This study was done using Jatropha biodiesel byproduct as...

Poly-Extremotolerant Bacterium Isolated from Reverse Osmosis Reject: an Implication toward Waste Water Management

C-Phycoerythrin is water soluble red color chromo-protein, which is used as a natural food colorant. The effect of selected edible preservatives like citric acid, sodium chloride, sucrose and calcium chloride on the stability of C-phycoerythrin at 0 +/- 5 degrees C and 35 +/- 5 degrees C was...

Cyanobacteria have many unexploited potential for natural products with a huge variability in structure and biological activity. Their products are species specific and substrate + growth condition specific. Under extreme/stress conditions they are reported to produce several biopolymers like...

A newly synthesized 1,4,8,11-tetraazacyclotetradecane derivative (L), functionalized with a diazo moiety as the reporter functionality, is found to bind specifically to Hg2+ with an associated change in color that could be visually detected. With biologically benign β-CD, it forms an inclusion...

Amylases are the most important hydrolytic enzymes for starch based industries. It is desirable that alpha-amylases should be active at high temperature of gelatinization (100-110 degrees C) and liquefaction (80-90 degrees C) to economize processes. Therefore, thermostable and thermoactive enzyme...

Specific recognition of CN(-) in sodium cyanide solution was achieved using two imidazole-based receptors (A and B). Visually detectable color changes were associated with the formation of hydrogen bonded adducts, A.CN(-) and B.CN(-). Ratiometric fluorescence response was achieved for receptor A...

Selective colorimetric detection of ATP in physiological conditions by a Zn(II)-based receptor is reported. This reagent was found to be non-toxic to the living cells and could be used for studying the growth of the yeast cells.

A new chemosensor (L1) is synthesized and its spectral response were screened with most alkali, alkaline earth,transtion and lanthanide meatl ions in THF-water (2:3, v/v, pH 7.2, 20mM HEPES buffer) medium. This is found to bind four different transition metal ions such as Hg2+, Cu2+, Ag+ and Ni2+...

The chromogenic complex 1· Zn (where 1 is (E)-4-(4- dimethylamino-phenylazo)-N,N-bispyridin-2-ylmethyl-benzenesulfonamide) showed high affinity toward the phosphate ion in tetrabutylammonium phosphate in acetonitrile solution and could preferentially bind to adenosine triphosphate (ATP) in...

Resonance energy transfer from dansyl to the rhodamine moiety in a newly synthesized chemosensor L2 has been utilized successfully for detection of Hg2+ in aqueous solution and living cells such as Pseudomonas putida.

A tetrapyrrole-based chromophore was obtained through the methanolysis of C-phycocyanin extracted from Spirulina platensis, and was found to act as a selective receptor for Hg2+ at physiological pH conditions.

The effect of selected edible preservatives, citric acid, sucrose and calcium chloride on the stability of C-phycocyanin (C-PC) at 0  5 8C and 35  5 8C was studied in aqueous solution. While screening the edible preservatives for a protein like C-phycocyanin, the denaturation of C-PC with...

A new chromogenic complex 1âZn has been synthesized, and its interactions with different biologically important phosphates have been investigated in aqueous solution (pH  7.2). A visual color change can be detected on binding of ATP to 1âZn, whereas no such change is observed when other...
