Studies on Some Lake-Mud Strains of Micromonospora.

چکیده
Representatives of the genus Micromonospora have so far been reported mainly from soil or, in the case of thermophiles, from composts. The type species, M. chalceae, described by ,2rskov (1923) who erected the genus, was first isolated by Foulerton (1905) under the name Streptothrix chalceae. This remained the only known strain among the Actinomycetes bearing the generic name Micromonospora until Jensen (1930, 1932) described a large number of soil micro-organisms which corresponded with Qrskov's description: "A branched unicellular mycelium is formed, consisting of very delicate hyphae with short lateral branches, each of which bears a single terminal spore." Recently, Waksman, Umbreit, and Cordon (1939) observed thermophilic strains of Micromonospora in composts and concluded from a study of the literature that some of the thermophiles isolated from soil or manure by Tsiklinsky (1899), from composts by Miehe (1907), and from decomposing clover hay by Schiitze (1908) should also come into this genus. The N.C.T.C. strain no. 4582 (Lister Institute) isolated by Gibson from blood culture in a case of Banti's disease and described by the writer (1935), which was tentatively classed as an Actinomyces (Qrskov's Group I) because of a sparse development of aerial mycelium, should probably be regarded as a Micromonospora of slow growth with scant lateral spore formation, resembling M. parva Jensen. Another strain corresponding with M. fusca Jensen was observed by the writer (1940) in a

Cellulose degradation by micromonosporas recovered from freshwater lakes and classification of these actinomycetes by DNA gyrase B gene sequencing.
A number of Micromonospora strains isolated from the water column, sediment, and cellulose baits placed in freshwater lakes were shown to be able to degrade cellulose in lake water without any addition of nutrients. A selective isolation method was also developed to demonstrate that CFU arose from both spores and hyphae that inhabit the lake environment. Gyrase B gene sequencing performed on th...
متن کاملThegenesis of micro-landforms of muddy and salty plains of Urmia Lake
Introduction Urmia Lake is one of the word-scale large hypersaline lakes with about 5500 square kilometers in the Turkish-Iranian Plateau (NW Iran). The lake surrounded by mountains with a mean elevation of about 2000 meters and the highest peak of 4811 meters. The lake charge with 28 permanent and ephemeral rivers. As a result of anthropogenic and natural reasons, the lake exposed to the rapi...
متن کاملMicromonospora lupini sp. nov. and Micromonospora saelicesensis sp. nov., isolated from root nodules of Lupinus angustifolius.
A study was conducted to determine the taxonomic status of six actinomycete strains isolated from root nodules of Lupinus angustifolius. The strains were filamentous, Gram-positive and produced single spores at the tip of the hyphae. Phylogenetic, chemotaxonomic and morphological analyses demonstrated that all six strains belonged to the genus Micromonospora. According to the 16S rRNA gene sequ...

Iran's mud volcanoes are clearly visible on the coastal plains of the Oman and Caspian Seas. There are 30 Gatan Mud Volcanoes located in the southeast of Iran: 15 of which are located between Jask and Minab in Hormozgan province, nine are between Chabahar and Jask Ports, and another six are between Chabahar and the Iran-Pakistan border in Sistan and Balouchestan Province. After some studies and...
