Salinispora tropica is an obligate marine actinomycetes bacterium species. Salinispora arenicola is an obligate marine actinomycetes bacterium species. Experiments show that they degrade chitin nearly as efficiently as chitinolytic actinomycetes. "Trichoderma" has an effect on actinomycetes. One of the most notable characteristics of the actinomycetes is their ability to produce antibiotics. The main microorganisms used are nonpathogenic actinomycetes, Nocardia and Streptomycetes. The GlgE pathway is especially prominent in actinomycetes, such as mycobacteria and streptomycetes. Salinispora pacifica is an obligate marine actinomycetes bacterium species in the genus Salinispora. Leupeptin is an organic compound produced by actinomycetes, which inhibits serine, cysteine and threonine proteases. Soil microorganisms can be classified as bacteria, actinomycetes, fungi, algae and protozoa. Non-"Streptomyces" actinomycetes, filamentous fungi, and non-filamentous bacteria, have also yielded important antibiotics. Actinomycetes - intermediate group between bacteria and fungi. Many species of Actinomycetes produce antimicrobial compounds under certain conditions and growth media. "Thermophilic actinomycetes" were also found in cannabis. Like most other ceanothus, this species fixes nitrogen via actinomycetes on its roots.
