Abstract
The antibiotic effects of foliage extracts of some forest trees on commercial Bacillus thuringiensis (Berliner) var. galleriae were studied with a view to determining whether or not such substances might be inhibitory to development and multiplication of ingested bacteria. The results indicate that ethyl acetate and petroleum or ethyl ether extracts of the trees tested were particularly inhibitory to the bacteria. Of 24 pure terpenes tested, pinene, pulegone, menthone, 4-terpineol, citral, citronellol, and linalool were highly inhibitory to the production of spores and crystals by the bacteria. Étude des effets antibiotiques des extraits foliaires de certaines essences forestières sur la Bactérie commerciale Bacillus thuringiensis (Berliner) var. galleriae, en vue de déterminer si ces substances pourraient inhiber ou non le développement et la multiplication des Bactéries ingérées. Propriétés particulièrement inhibitoires pour les Bactéries, selon les résultats obtenus, des extraits d’actate d’éthyle et de pétrole ou d’éther éthylique obtenus des essences étudiées. Des 24 terpènes purs examinés, seuls le pinène, le pulegone, le menthone, le 4-terpineol, le citral, le citronellol et le linalool étaient fortement inhibitifs pour la production de spores et de cristaux par les Bactéries.Keywords
