摘要

1-Chloro-5-methylene-7-hydroxy-9,9-dimethyl-spiro[5.5]undec-2-ene (I) is used in the form of Laurencia seaweed biomass or an extract thereof. 1-Chloro-5-methylene-7-hydroxy-9,9-dimethyl-spiro[5.5]undec-2-ene of formula (I) is used in the form of Laurencia seaweed biomass or an extract thereof: [Image] An independent claim is also included for an animal feed comprising Laurencia seaweed biomass and an inorganic thiocyanate in an amount providing a daily dose of thiocyanate ions of 10-20 mg/kg. ACTIVITY : Antibiotic. The zone of inhibition produced by placing a 6 mm sensi-disc coated with a Laurencia chondrioides extract (no details given) on a Pseudomonas anguilliseptica culture and incubating at 26 [deg]C for 18 hours was 8.8 mm. MECHANISM OF ACTION : None given.
