We report here the complete genome sequence of Mesorhizobium sophorae ICMP 19535T This strain was isolated from Sophora microphylla root nodules and can nodulate and fix nitrogen with this host and also with Sophora prostrata, Sophora longicarinata, and Clianthus puniceus The genome consists of 8.05 Mb.

background: one of the most important environmental pollutants is industrial wastewaters. discharging of colorful industrial effluents to receptive waters can lead to eutrification and it has the carcinogenic and mutagenic properties. therefore, the aim of this study is evaluation of acid blue 15 dye removal by dried azolla from aqueous solution. material and methods: the azolla biomass was dri...

A study was undertaken to evaluate the nutritive value and digestibility of Azolla in ruminants by in vitro techniques. The crude protein, crude fibre and ether extract contents were at a level of 21.37%, 12.5% and 2.3%, respectively. The neutral and acid detergent fibre levels were about 35.4 and 23.9%, respectively. The average in vitro dry matter digestibility, in vitro organic matter digest...

Visible absorption spectra are presented for the Azolla caroliniana Willd.-Anabaena azollae Strass. association and the individual partners. Although absorption by the phycobiliproteins of the endophytic cyanobacterium clearly complements the absorption by the fern pigments, their contribution to the absorption spectrum of the association is effectively concealed by the preponderance of the Azo...

 The aquatic fern Azolla, a small-leaf floating plant that lives in symbiosis with a nitrogen fixing cyanobacteria (Anabaena), is an outstanding plant, thanks to its high biomass productivity along with its tremendous rate per unit area for nitrogen-fixation.  The present study investigates the potential growth of Azolla in secondary effluents for removal of COD, phosphorus, and nitrogen. Resul...

Floating ferns of the genus Azolla detach their roots under stress conditions, a unique adaptive response termed rapid root abscission. We found that Azolla pinnata plants exhibited dose-dependent rapid root abscission in response to the polyamines spermidine and spermine after a substantial time lag (>20 min). The duration of the time lag decreased in response to high pH and high temperature w...
