title: Marine algae that display anti-tumorigenic activity against Agrobacterium tumefaciens.
abstract: Thirty-five extracts representing different seasonal growths of 17 marine algal species collected from the Alexandria coast were tested for anti-tumorigenic activity against Agrobacterium tumefaciens galls on potato discs. Eleven extracts (nine species) displayed > 20% inhibition of tumor initiation, with three of these (Codium tomentosum, winter; Jania rubens, summer; Padina pavonia, winter) displaying relatively high activity. Bacterial viability tests showed that the inhibitory effects were directly due to anti-tumorigenesis rather than an indirect result of anti-bacterial activity.
