Appraisal of Antimicrobial Activity of Malted Psedocereals: Amaranthus cruentus (Amaranth)And Fagopyrum csculentum (Buckwheat)
Journal Title: International Journal of Research in Pharmacy and Science - Year 2013, Vol 3, Issue 2
Abstract
The aim of this work was to evaluate antibacterial activity of malted extracts of Amaranthus cruentus (Amaranth) and Fagopyrum esculentum (Buckwheat); pseudocereals with plain water and alkali 2% NaHCO3against the eight species of Gram-positive (Staphylococcus auerus, Streptoccocus pyogenes. ,Bacillus cereus) and Gram-negative bacteria (Escherichia coli,Proteus vulgaris, Shigella sp., Klebseilla pneumonia, Psedomonas aeruginosa). Antimicrobial activity of extracts was tested by the disc diffusion method according to the National Committee for Clinical Laboratory Standards Guidelines.It was observed in the present result that Fagopyrum esculentum and Amaranthus cruentus alkali (2% NaHCO3) treated extract was found to have maximum zone of inhibition against E.coli (12.3±0.41mm and 10.5±0.75mm) and B. cereus (10.0±0.2mm and11.1±0.10mm) while the minimum zone of inhibition was against streptococcus (5.3±0.30 mm) for amaranth alkali malted extract.Thus, the findings suggest that malted extract of buckwheat and amaranth may be considered as moderate antibacterial agent against the food borne pathogens and could be used as natural ingredients with their antimicrobial effects in food industry.
