Abstract

Abstract
Edible white button mushroom is a secondary decomposer and the activity of other micro-organisms is necessary to decompose the raw compounds for its growth. Actinomycetes bacteria due to their ability to decompose the compound molecules such as cellulose, lingo-cellulose and lignin, play an important role in the composting process for the mushroom. Bacterial biomass of actinomycetes contains a high rate of nitrogen and minerals, necessary for growth of the mushroom. To investigate the effects of actinomycetes on growth of mushroom mycelia, isolates of the genus of Streptomyces ،Saccharomonospora, Thermomonospora, Nocardioides, Saccharopolyspora, Microbispora, Glycomyces were used for inoculating of sterile compost and preparing bacterial biomass. The result showed that inoculating of compost with actinomycetes could have a significant effect on the growth of mushroom mycelia, compared to the control. Isolates belonging to the genus Streptomyces supported a higher growth of the mushroom mycelia.
