Competitive exclusion as a mode of action of a novel Bacillus cereus aquaculture biological agent

Author: Lalloo, Rajesh ; Moonsamy, Ghaneshree ; Ramchuran, Santosh O ; Görgens, J ; Gardiner, N Date: 2010 When B. cereus was tested in plate well inhibition studies, no production of antimicrobial compounds was detected. B. cereus had a high growth rate (0.96.h−1), whereas Aer. hydrophila concentration decreased by ∼70% in co-culture experiments. ... Read more
Downstream process for production of a viable and stable Bacillus cereus aquaculture biological agent

Author: Lalloo, Rajesh ; Maharajh, Dheepak M ; Görgens, J ; Gardiner, N Date: Mar 2010 Biological products offer advantages over chemotherapeutics in aquaculture. Adoption in commercial application is lacking due to limitations in process and product development that address key end user product requirements such as cost, ... Read more
High-density spore production of a B. cereus aquaculture biological agent by nutrient supplementation

Author: Lalloo, Rajesh ; Maharajh, Dheepak M ; Gorgens, J ; Gardiner, NS ; Gorgens, JF Date: May 2009 Previous studies have demonstrated the efficacy of our Bacillus cereus isolate (NRRL 100132) in reducing concentrations of nitrogenous wastes and inhibiting growth of fish pathogens. In vivo efficacy and tolerance to a range of physiological ... Read more
Isolation and selection of Bacillus spp as potential biological agents for enhancement of water quality in culture of ornamental fish

Author: Lalloo, Rajesh ; Ramchuran, Santosh O ; Ramduth, DM ; Gorgens, J Date: Feb 2007 Natural isolates obtained from mud sediment and Cyprinus carpio were purified and assessed in vitro for efficacy based on the inhibi-tion of growth of pathogenic Aeromonas hydrophila and the decrease in concentrations of ammonium, nitrite, ...
