“…A similar phenomenon was also reported by and his group, where the level of scaling due to calcium carbonate formation in the reactor was so high that the reactor had to be shut down. Sakairi et al (1997) reported that bicarbonate ions were deprotonated in the presence of ammonia. This raises the carbonate concentration in the solution to such an extent as to exceed the solubility product of calcium and magnesium carbonates (Ca + and Mg 2+ are present in seawater), which then precipitate out of the solution.…”

“…Conversely, the work of Bright and Fletcher (1983) found that marine bacteria preferred hydrophilic substrata. CatalanSakairi et al (1997) found that a polyester carrier was more effective than cellulose in a marine bacterial nitrification fermentation. Other influencing factors, such as pH, salinity and temperature, remain to be quantified; however, Costerton et al (1995) have observed that Pseudomonas aeruginosa creates biofilms during periods of favorable nutrient conditions.…”

: There is a lack of research into bioreactor engineering and fermentation protocol design in the field of marine bacterial antibiotic production. Most production strategies are carried out at the shake-flask level and lack a mechanistic understanding of the antibiotic production process, offering poor prospects for successful scale-up. This review shows that data need to be collated on media and physical optima differences between the trophophase and idiophase, along with investigations into the control mechanisms for biosynthesis, to allow implementation of novel fermentation protocols. Immobilization may play a part in bioprocess intensification of marine bacterial antibiotic production, through again this area is understudied. Similarly, mass transfer and shear stress data of fermentations are needed to provide the bioreactor design requirements to intensify antibiotic biosynthesis, with process scale-up in mind. The application of bioprocess intensification methods to the production of antibiotics (and other metabolites) from marine microbes will become an important strategy for improving supply of natural products, in order to assess their suitability as chemotherapeutic drugs.

“…According to Catalan‐Sakairi, Wang & Matsumura (1997), different factors can affect the nitrification process in seawater. Important parameters are the inorganic carbon concentration, the trace‐element concentration and the physicochemical properties of the carrier.…”

A dense nitrifying culture (ABIL) has been examined for its capacity to stimulate rotifer growth in a labscale culture system. The nitrifiers were applied in different ways. When ABIL was added directly to rotifer batch cultures, it gave rise to significantly higher population densities (factor 1.5±2.5 higher, P < 0.05). The nitrifiers were subsequently examined for their capacity to enhance the start-up of bioreactors, commonly installed in aquaculture rearing tanks. Of the different carrier materials used in these bioreactors, i.e. CaCO 3 , gravel and a PVC matrix (Bionet), CaCO 3 gave by far the best results. In a third set of experiments, effectively nitrifying bioreactor systems were connected to rotifer culture tanks and operated over a period of up to 10 days. It was demonstrated that the ABIL inoculated CaCO 3 -based bioreactor allowed excellent rotifer growth reaching rotifer densities up to 5500 rotifers per mL. Moreover, a new system in which the ABIL culture was recirculated through hollow fibres was developed and demonstrated to be effective for supporting rotifer growth up to 3500 rotifers per mL. Overall, the use of the dense nitrifying culture either in seed batch cultures, conventional bioreactors or hollow fibre bioreactor systems in support of rotifer cultures was demonstrated to be effective for improving the water quality and the rotifer growth.
