Abstract:
:Alcaligenesfaecalis (CCT 7145) was isolated from an Amazonian soil sample after an enrichment process to select for phenol-degrading microorganisms. The isolate was labeled with the green fluorescent protein (gfp) gene. The gfp-transformed cells were easily detected using a hand-held UV transilluminator and their taxonomy was confirmed by 16S rRNA sequencing. Polymerase chain reaction (PCR) and Southern blot analyses confirmed that the gfp gene was integrated into the chromosome. The addition of the gfp marker did not affect phenol degradation ability compared with the wild-type. Both, wild-type and gfp-marked A. faecalis cells encapsulated in alginate, tolerated 1,700 microg ml(-1) phenol in liquid medium compared with 1,100 microg ml(-1) phenol for free cells. 14C-Phenol mineralization in soil microcosms was also enhanced by inoculation with encapsulated cells. Survival of gfp-marked cells in phenol-contaminated soil over 22 days was determined from plate counts using an epifluorescence microscope.
