Streptomyces spp. were isolated via sampling during thermophilic phase of a compost system. Isolates were subjected to a careful and detailed sets of procedures in order to select best candidates effective on organic matter degradation. This effect, on organic matter degradation was illumanated by evaluation of composting experiments and metagenome analyses in accordance. Results indicated dominanace of strains when added to compost systems. This dominanace was found to be partially due to possible secondary metabolite production of isolates determined by antagonism tests. The dominance of strains was in fact distinctive in establishment of variant organic matter degradation. Enzymatic activity as a result of strains' dominance was provided as an explanation based on evaluation of metagenomic counts. Metagenome count numbers revealed the tendency of compost microbiota towards degradation products of cellulose and xylan was also determined to be least favored polysaccharide. Results also implied a decrease of competition between the dominant strain and microbita members in the case of sequential cellulose and xylan degradation. Meticulous evaluation of results obtained from metagenome analysis also provided some insights on certain conditions regarding the progress of composting along with storage conditions of manure prior to use.

“…Micromonospora members are regarded as rich biosources of novel bioactive compounds with promising uses in medicine due to their ability to produce antibiotics (probably the second antibiotic producer after Streptomyces), antitumor substances, enzyme inhibitors, and antioxidants [4][5][6]. Moreover, the biochemical properties of Micromonospora show its potential for use in various biotechnological processes, such as nitrogen preservation in composting [7], the degradation of organic and artificial polymers [8][9][10], and even in the concrete industry as a biohealing agent [3]. The beneficial influence of these bacteria on soil ecology and plant growth and development has recently been elucidated [5].…”

Bacteria belonging to the genus Micromonospora are recognized as microorganisms with the potential to be used in biotechnology processes, given their beneficial influence on plant growth and the biocontrol of phytopathogens. In this study, nineteen Micromonospora isolates originating from the root nodules of white clover plants were taxonomically assigned based on the phylogenetic analysis of the 16S rRNA gene and four housekeeping genes. The antifungal properties of the bacteria against phytopathogenic Botrytis cinerea, Fusarium oxysporum, Fusarium equiseti, Sclerotinia sclerotiorum, and Verticillium albo-atrum were tested with the agar plug test and the dual culture test. The ability to produce various metallophores was determined with the agar plug diffusion test on modified chrome azurol S (CAS) agar medium. International Streptomyces Project-2 medium (ISP2) broth amended with 0.2% L-tryptophan was used to indicate the bacterial ability to produce auxins. The strains belonging to M. tulbaghiae, M. inaquosa, and M. violae showed in vitro potential as antimicrobial agents against the tested fungi. M. inaquosa strain 152, M. violae strain 126, M. violae strain 66, and M. violae strain 45 were recognized as the most efficient metallophore producers. M. alfalfae strain 55 and M. lupini strain 5052 were identified as the most promising auxin compound producers and, therefore, show potential as plant-growth-promoting bacteria.
