Liquid broth-no agar-turbidity-used for the right cultivation ex: nutrient broth. An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies. Agar (extracted from sea weed) is heated along with different materials like water and nutrients then after its homogenized, its cooled down a bit then its poured in petri dishes to solidify. endstream endobj 21 0 obj <> endobj 22 0 obj <>stream … The culture medium is a solid, semi-solid or liquid substrate that is rich in nutrients and other necessary elements and supports the growth of microorganisms. 1) Classification based on consistency: C) Semi-solid agar: Such media are fairly soft and are useful in demonstrating bacterial motility and separating motile from non-motile strains Hugh & Leifson’s oxidation fermentation 10. Upon cooling, the agar formed a stable, semi-solid gel. Motile bacteria move with structures called flagella (a few exceptional bacteria move with the help of axial filaments, which cannot be seen in the microscope). Phenolphthalein, an acid–base indicator, was added to detect the formation or presence of hydroxide ions. Using this medium De Smedt and Bolderdijk have reported the possibility of detecting Salmonella in 24hrs (1987). 8E­Šz³ÜoYºµº­mìC=´DÛê(QÕK¼ì×ï9’Š­8q1yy|îî¹ãi7ùƒUÎ|üq–Fޏ™ï1ËJ¼z?ñ½˜íل֔øåÌ™š\O>O¾»½3΂4ôæ. endstream endobj 20 0 obj <>stream Blood agar uses sheep blood to help grow fastidious microbes including streptococci.
