| Summary: | Includes b&w maps; b&w charts; bibliographic references Samples of Mytilis edulis (mussel) were collected from coastal sites randomly selected on the south·eastern shores of Prince Edward Island and from similar locations on the southern shore of Cape Breton Island. Cultivation of aliquots of tissue from these animals revealed a diverse fungal flora from which 49 cultures of the genus Trichoderma were isolated. The number of propagules from which these cultures were derived was multiplied by a factor to reflect the dry weight of mussel tissue used in the isolation. A random sample of 29 isolates from this theoretical collection was then selected and it was found possible to cultivate 28 of these in the laboratory. All nine isolates of Trichoderma hamatum, produced isocyanide metabolites. Improvements in the assay of these compounds are reported. Des échantillons de Mytifis edulis (la moulel) ont été collectionnés à locations côtières choisies au hasard sur les côtes sud-est de l' lle Prince-Edouard et sur des lieux semblables sur la côte sud du Cap Breton. La cultivation d'aliquotes de ces animaux a révélé une flore variée de moisissures desquelles 49 cultures de ce genre ont été isolées. Le nombre de propagules qui ant fait partie de ces cultures a été multiplié par un facteur afin de réfléchir le poids sec du tissu de moule utilisé dans cette isolation. Un échantillon de 29 isolates de cette collection théorique a été choisi, et on a réussi à en cultiver 28 dans le laboratoire. Tous les neuf isolates de Trichodem hamatum ont praduit des metabolirtes de l'isocyanure. On disc ute des améliorations du titrage de ces composés. |
