Notes: An Antibiotic Detected in Conifer Foliage and its Relation to Cenococcum graniforme Mycorrhizae
Abstract:Cenococcum graniforme formed abundant mycorrhizae with Pinus strobus, P. resinosa, and Picea abies growing in pure plantations on two soil types in central Pennsylvania. Roots of these species growing in Morrison sandy loam had more C. graniforme mycorrhizae than those in Calvin-Edom silty clay loam. Picea abies showed the greatest number of mycorrhizae per unit length of root and Pinus strobus the fewest. An antibiotic similar to that produced by C. graniforme in vitro was detected in needles of each species. Bioassay of the Cenococcum antibiotic with Bacillus cereus indicated a significantly greater antibiotic activity in P. strobus than in P. resinosa. Picea abies extracts contained the antibiotic but apparently not in sufficient quantity to inhibit B. cereus.
