Pseudoalteromonas sp. strain C4 as a probiotic for farmed South African abalone, Haliotis midae
The objective of this study was to identify a potential probiotic bacterium that increased the growth and decreased the susceptibility of farmed abalone to pathogenic bacterial infection. The mechanism by which the probiotic is able to increase growth rates and reduced susceptibility to pathogen infection was investigated. A number of bacterial strains were isolated from the digestive tract of Haliotis midae that are capable of degrading a wide variety of different polysaccharides (Erasmus, 1996). Strain C4 was selected for further investigation as a result of its ability to degrade alginate since H. midae is predominantly fed a kelp diet of which the major component is alginate.
