Bacterial communities of seven lakes in the Adirondack Mountains of New York State were characterized by amplification and sequencing of 16S ribosomal DNA. Analysis of over 100 partial sequences revealed a diverse collection of lineages, largely of the class Proteobacteria (19% alpha subdivision, 31% beta subdivision, and 9% gamma subdivision), the phylum Cytophaga-Flavobacteria-Bacteroides (15...
Catenulispora acidiphila Busti et al. 2006 is the type species of the genus Catenulispora, and is of interest because of the rather isolated phylogenetic location it occupies within the scarcely explored suborder Catenulisporineae of the order Actinomycetales. C. acidiphilia is known for its acidophilic, aerobic lifestyle, but can also grow scantly under anaerobic conditions. Under regular cond...
A new antibiotic I-11, was isolated from the mycelial cake of strain I-11, an antibiotic-producing microorganism isolated from soil samples collected in the vicinity of Madras, India. The strain exhibits several modes of growth that differ from those of the Streptomycetes and Actinomycetales, but similar to certain fungi'). Strain I-I1 grows fairly well on all of the media employed according to...
A simple and selective assay system was developed in the search for new insecticidal substances from Actinomycetales strains propagated on solid culture media. The strains were first tested for their ability to produce antimicrobial compounds. Only strains displaying weak or no activity were retained and screened in the insecticidal bioassay. Microbial solid cultures were given as food to larva...
A major taxon of obligate marine bacteria within the order Actinomycetales has been discovered from ocean sediments. Populations of these bacteria (designated MAR 1) are persistent and widespread, spanning at least three distinct ocean systems. In this study, 212 actinomycete isolates possessing MAR 1 morphologies were examined and all but two displayed an obligate requirement of seawater for g...
