TAILIEUCHUNG - Isolation and characterization of larvicidal extracellular polysaccharide (EPS) from Pseudomonas aeruginosa B01

In the present study extracellular polysaccharide (EPS) was characterized from Pseudomonas aeruginosa B01. EPS was purified using ethanol precipitation and dialysis. The purified EPS from P. aeruginosa B01 was analyzed using a High Performance Liquid Chromatography (HPLC). The infrared spectra of EPS from P. aeruginosa B01 clearly showed the presence of carboxylate groups. The FT-IR spectrum indicated an intense absorption band in the region of 3296 cm-1 on the stretching vibration of hydroxyl groups (OH). The bands in the region of 2941 cm-1 and 1627 cm-1 are due to stretching vibrations of C-H bonds. The absorption in the region of cm-1 indicated the presence of glycoside link in the alpha (α) conformation. | Isolation and characterization of larvicidal extracellular polysaccharide (EPS) from Pseudomonas aeruginosa B01
