The synergy between bacteria and phytoplankton is relatively not well understood, but natural bacteria in cultures is thought to be important for maintaining natural growth patterns, behavior, and compound production in the strains. For this reason the majority of ARC strains do have bacteria present, however, ARC houses a small subset of bacteria-free clones that are available for purchase. Any of the strains housed at ARC can be made bacteria-free, but this will be done upon request. Please contact ARC staff if you require a strain to be treated with antibiotics.
ARC houses a selection of non-toxic, fast-growing flagellates that are common food sources for oysters. Please refer to the list here.
