Microbial colonization and competition on the marine alga Ulva australis
Article Abstract:
The hypothesis that Pseudalteromonas tunicata and Rosebacter gallaecienses are effective colonizers of Ulva australis and are able to compete with and dominate other marine bacterial isolates during biofilm formation on plant surface is investigated. The findings showed that microbial colonization of plant surfaces is a dynamic process in which attachment, colonization and competitive biofilm formation can affect the establishment and organization of epiphytic microbial communities.

Enhanced benzaldehyde tolerance in Zymomonas mobilis biofilms and the potential of biofilms applications in fine chemical production
Article Abstract:
Biofilm resistance and biotransformation capacity in a model system using Zymomonas mobilis for the transformation of benzeldehyde was investigated with a view to illustrating the potential for use of biofilms in fine-chemical production. Microscopic analysis and metabolic activity studies revealed that Z. mobilis biofilm cells were more tolerant to the toxic substrate benzaldehyde and this enhanced tolerance was not due to the conversion of benzeldehyde into less toxic compounds.

Low densities of epiphytic bacteria from the marine alga Ulva australis inhibit settlement of fouling organisms
Article Abstract:
The density dependence of anti-fouling activity of Pseudoalteromonas tunicata and Phaeobacter sp. strain 2.10 biofilms and their inhibitory effects at ecologically relevant densities are tested. The results have shown that Pseudoalteromonas tunicata and Phaeobacter sp. strain 2.10 have played a key role in defense against fouling in Ulva australis at cell densities.
