Description
HHD Broth is a differential liquid medium for distinguishing heterofermentative from homofermentative lactic acid bacteria.
Homofermentative bacteria cause a bromocresol-green colour change and form a blue-green sediment. Heterofermentative bacteria produce a different acidification pattern and a white sediment.
The PDF describes inoculation followed by incubation at 30°C for three days.
