development of an environmental friendly and cost-effective process for microbial degradation of caffeine to non-toxic compounds are promising to solve the problems of physiochemical extraction of caffeine in the treatment the caffeine containing agro-industrial effluents. thirteen bacterial strains, isolated from tea plantation soils in the north region of iran, were screened to show their abi...

BACKGROUND AND OBJECTIVES Microbial caffeine removal is a green solution for treatment of caffeinated products and agro-industrial effluents. We directed this investigation to optimizing a bio-decaffeination process with growing cultures of Pseudomonas pseudoalcaligenes through Taguchi methodology which is a structured statistical approach that can be lowered variations in a process through Des...

Background:Foam cells are markers of atherosclerosis and characterise advanced atherosclerotic plaque, stimulated by inflammation caused high lipid levels in macrophages. The combination decaffeinated coffee green tea extract (DCGTE) has been suggested to have a role foam cell inhibition.Objective: we investigated the inhibiting DC...

maceutical industry for production of fine drug particles with narrow size distribution, separation of active ingredients and preparation of microemulsions and sustained drug delivery systems. Supercritical carbon dioxide (SC-CO2) is a very popular fluid for pharmaceutical applications, as it is nontoxic, non-flammable and of low cost. Furthermore, because of its low critical temperature and pr...

T he thought of liquid CO2 conjures up different things to different folks: perhaps the decaffeination of coffee beans, perhaps the recently popularized ‘‘green’’ method for dry cleaning, or even phase diagrams that occupied a part of one’s life in past chemistry classes. What it does not conjure up is a subsurface lake at the bottom of the ocean, a lake with abundant living microbes, as report...
