DESCRIPTION:A major roadblock to the commercialisation of algae for indust
 rial biotechnology is the contamination of cultures via adventitious organ
 isms\, such as bacteria. However\, algal-bacterial interactions are common
  in nature\, and many algae require bacterial symbionts for the provision 
 of key nutrients such as vitamin B12. In order to improve the commercial p
 rospects of large-scale microalgal culture\, I am investigating the potent
 ial for algal-bacterial consortia to reduce contamination by adventitious 
 bacteria and improve the stability and productivity of algal cultures. Uti
 lising a model algal-bacterial symbiosis between the green alga Lobomonas 
 rostrata and the rhizobial bacterium Mesorhizobium loti\, I have investiga
 ted the role of bacteria in the phycosphere and the effects of bacteria on
  algal growth. I will present my research into the potential probiotic eff
 ects of mutualistic bacteria and describe a novel protocol for the co-cryo
 preservation of algae and bacteria\, within the scope of industrial biotec
 hnology.
