In 451000 hadronic Z0 decays, recorded with the ALEPH detector at LEP, the yields of lambda l- and lambdal+ combinations are measured. Semileptonic decays of b baryons result in a signal of 122 +/- 18(stat.)+22/-23(syst.) lambda l- combinations. From a fit to the impact parameter distribution of the leptons in the lambda l- sample, the lifetime of b baryons is measured to be 1.12+0.32/-0.29(stat.) +/- 0.16(syst.) ps
