MATOS CUZCANO, Gisella  and  ZUNIGA DAVILA, Doris. Viabilidad de cepas de rizobios en inoculantes basados en soportes no estériles. Ecol. apl. [online]. 2003, vol.2, n.1, pp.81-85. ISSN 1726-2216.

The survival of Bradyrhizobium sp. PLL113 and Rhizobium sp. PLC213 in soil-compost and peat based unsterile inoculants stored at 4 °C during 6 months was evaluated. The populations of both strains decreased during storage in both type of inoculants, although better survival was observed in peat. Evidence of antagonisms or competition between total contaminant bacteria and moulds was registered. In addition, negative correlations were observed between rhizobial populations and the rest of microorganisms, which indicated its poor competitiveness against contaminants. The inoculants microbiological quality was satisfactory during the first seven weeks of storage.

Keywords : Rhizobium; compost; peat; nodules.
