Ultrasound assisted extraction of proteins from spirulina platensis and its recovery using aqueous biphasic system

Abstract

Micro algae is one of the promising sources of nutrients It is consumed as a food for many centuries used for the production of biodiesel or bioethanol and at present it is being explored for the production of cosmetics and pharmaceuticals The current state of the art micro-algae production producing systems mainly caters for the food industries Currently newlinemicroalgae are used for the extraction of high value protein carbohydrate andcolorants The main steps involved in the production of protein from dried whole algae is the disruption which break the cell wall and facilitate there lease of high-value compounds into the aqueous media The extraction of specific components from microalgae is hindered by the rigidity of the cell wall To overcome this better cell disruption methods need to be developed Ultrasound irradiation disrupts the cell wall of microalgae based on the cavitation phenomena This present study focuses on the ultrasound assisted extraction of protein from Spirulina platensis and its process parameters optimization Also on the recovery of proteins by Aqueous Biphasic System ABS PEG IL and salt The development of method that newlinecombines ultrasound and chemical reagents (acid alkali and water) as well as ABS performance were studied at length. newline newline
