Marine macroorganisms are a potential source for new bioactive substances. In many cases marine microorganisms-especially bacteria-associated with these macroorganisms are actually producing the bioactive substances. One often is not able to immediately isolate microorganisms from collected macroorganismic materials; we therefore evaluated different methods for storage of such material, e.g., on board research vessels. These methods were the following: storage of macerates in sintered glass beads and 5% trehalose at -20degreesC (SGT method); storage of sections in 5% dimethyl sulfoxide at -70degreesC (SD method); storage of macerates at -20degreesC using the commercial ROTI-STORE system (RS method); storage of macerates at -20degreesC in 50% glycerol (GC method); and storage of macerates covered by mineral oil at 4degreesC (MO method). The SGT and SD methods resulted in numbers of and especially diversity of recoverable bacteria that were higher than for the other methods. Data for the RS method indicated its potential usefulness, too. The MO method resulted in growth during storage, thereby enriching a few selected microorganisms; the GC method resulted in a survival and diversity of recovered bacteria that was too low.
