Summary Mycolic acid‐containing actinomycetes capable of metabolizing nitriles were recovered from deepsea sediments and terrestrial soils by enrichment culture on acetonitrile, benzonitrile, succinonitrile or bromoxynil. A total of 43 nitrile‐degrading strains were isolated and, together with previously reco‐vered nitrile‐degrading rhodococci, were identified by a polyphasic taxonomic approach, which included mycolic acid pro...

Acacia mangium and Paraserianthes falcataria are leguminous tree species widely grown for timber in Indonesia and other tropical countries, yet little is known about the identity of their rhizobial symbionts. Polymerase chain reaction‐restriction fragment length polymorphism‐single‐strand conformational polymorphism (PRS) analysis of the 16S rRNA gene was used along with sequencing to assess the diversity of 57 rhizobia isolat...
