Survival of a genetically engineered Rhizobium isolate incubated in soil microcosm [ electronic resource].

Includes reference.

Twenty one Rhizobium isolates were isolated from different agricultural soil locations which represented eleven different plant hosts. All isolates were identified genetically and microbiologically. Twenty one rhizobiophage Iysates were prepared from lysogen and examined for host rangc and lysis abilities. These phages were classified into two groups: Iysates that couldn't infect or lysis the same host cells that are released from, and Iysates that could lysis the same host cell. Resistance to antibiotics (streptomycin ,tetracycline, ampicilin and rifampicin) was examined for all of isolates and observcd in a varying way in many of isolates. Transducability of streptomycin mediated by five of rhizobiophages was examined.
