The Suitability of a Various Gelling Agents as Agar Substitute in Microbiological Growth Media
Abstract: Three gelling agents were investigated as agar substitutes. These include cassava starch, Potato starch and carrageenan. Among these carrageenan was found to be a alternate candidate for agar. Media solidified with 3% carragenan was more transparent and supportive for the growth of seven test bacteria (E.coli, Klebsiella, Proteus, Pseudomonas Staphylococcus aureus, Salmonella Typhi and Serratia) as good as agar. Comparing carrageenan to agar, it also performed better in terms of cost-benefit analysis. Carrageenan concentration varies in various cultural media compared to agar.
