Bold Modified Freshwater Nutrient Solution (Modified Bold Basal Medium; Modified BBM) |250g (can prepare 333L liquid medium)

Bold Basal Medium Modified with trace elements and replaced MoO3 with Sodium Molybdate.


Applications

Modified Bold Basal Medium is an axenic-culture maintenance medium in phycology/algae studies.

Commonly used for the cultivation of a variety of freshwater algae cultures (e.g. Trichosarcina, Chlorococcum, and Chlorella) without the need for soil-extract or vitamins (Brown et al., 1964; Nichols and Bold, 1965). Other algae species like Zygnemataceae(Zygogonium ericetorum) can also be grown in Bold’s Basal Medium(Stancheva et al., 2014)
