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 .

This video describes soil fungi, which are a diverse group of eukaryotic organisms that have rigid cell walls and lack chlorophyll. Soil fungi often make up more biomass in soil than any other microbial group. These filamentous organisms are heterotrophic, which means they consume organics as a carbon source.   Fungi can produce abundant hyphae (or threads) that are able to extract nutrients and water from many locations within the soil matrix. Also, fungi are active in decomposing plant residues and animal tissues. The video shows a close-up of fungal hyphae active in decomposing an insect or macrofauna (relatively larger animal). Most fungi that grow on artificial media originate from asexual spores. This group informally is called Fungi . Code no. 618B. . Pre-MSc. Students. Lecture no. 5 (15-3-2020). D. r.
