Blood Agar Base with Low pH, HiVeg, 500G

Used as a basal medium for preparing blood agar by supplementation with blood. It can also be used as general-purpose media without the addition of blood. The low pH of Hiveg Blood Agar Base w/ low pH (pH 6.8) stabilizes the red blood corpuscles and favors the formation of clear zone of haemolysis. Also it is advantageous for cultivation of Streptococci and Pneumococci Blood Agar Base media can be used with added phenolphthalein phosphate for the detection of phosphate producing staphylococci, to determine salinity range of marine Flavobacteria. It can also be used for preparation of Salmonella Typhi antigens. Application: For Isolation & Cultivation of Fastidious Organisms Appearance of Powder: Yellow colored, may have slightly greenish tinge, homogeneous, free flowing powder Gelling: Firm comparable with 1.5% Agar gel of MV073 and MV089 Color and Clarity: Basal medium yields light amber colored clear to slightly opalescent gel. Addition of 5% v/v sterile defibrinated blood yields cherry red opaque gel in petri plates Reaction of 4.0% w/v aqueous solution of MV073 is pH 7.3 ± 0.2 at 25°C and of MV089 is pH 6.8 ± 0.2 at 25°C Cultural characteristics observed after an incubation at 35 - 37°C for 18-48 hours
