Abstract

SUMMARY: Two new species of the genus (Trev.) have been isolated from the soil of chalk grassland. One of these, n.sp., fixes atmospheric nitrogen in culture in amounts of 2–4·5 mg. N/g. glucose, sucrose or mannitol present in the medium. The second species, n.sp., decomposes cellulose in culture and fixes atmospheric nitrogen in culture using glucose, sucrose, mannitol and cellulose as carbon source; amounts of 12 mg. N fixed/g. cellulose decomposed were recorded. The properties of nitrogen fixation and cellulose decomposition have not previously been recorded for this genus. The two organisms are described.
