Casman HiVeg Broth Base, 5KG

Casman HiVeg™ Broth Base is used for isolation of fastidious microorganisms from clinical specimens under reduced oxygen tension. Proteose peptone, tryptose and HM Peptone B provide amino acids and other complex nitrogenous nutrients. Dextrose improves growth of pathogenic cocci. Corn starch prevents fatty acids from inhibiting the growth of Neisseria gonorrhoeae, without interfering with haemolytic reaction. Corn starch also neutralizes the inhibitory action of dextrose. This medium supports growth of Haemophilus influenzae, Neisseria meningitidis, Streptococcus mitis, Streptococcus pneumoniae, Streptococcus pyogenes and other fastidious organisms. This medium is prepared by replacing animal peptones with vegetable defined peptones to avoid BSE/TSE/GMO risk. Appearance of Powder: Light yellow colored, may have slightly greenish tinge, homogeneous, free flowing powder Gelling: Firm, comparable with 1.4% Agar gel of MV201 Color and Clarity: Basal medium is yellow colored, clear to slightly opalescent gel. With addition of blood cherry - red colored opalescent gel forms in petri plates, cherry red, colored opalescent solution in tubes Reaction of 4.36% w/v aqueous solution of MV201 is pH 7.3 ± 0.2 at 25°C, Reaction of 2.96% w/v aqueous solution of MV766 is pH 7.2 ± 0.2 at 25°C Cultural characteristics observed after an incubation at 35-37°C for 40-48 hours
