Loynachan Citation Thomas Loynachan 2008 Soil actinomycetes Publication Date June 2008 Introduction Actinomycetes is a nontaxonomic term for a group of common soil microorganisms sometimes called thread or ray bacteria They are known for decomposing more resistant organic materials such as chitin a complex sugar found in the outer skeleton of insects and elsewhere Actinomycetes are simple prokaryotic organisms that are gram positive have a high GC base composition and are mycelium thread forming Nucleic materials DNA consist of a helical structure with a sugar backbone attached through the bases adenine thymine AT and guanine cytosine GC Compared with the DNA of other organisms actinomycetes have a high percentage of guanine cytosine bases In growth habit many actinomycetes resemble fungi but are smaller and terms common to both are used to describe morphological features The most common genus of actinomycetes in soil is .
