The effects of the recombinant YeaZ of on the resuscitation and growth of soil bacteria in extreme soil environment.

Numerous bacteria entered the viable but non-culturable state due to the stresses of dry and salt in soils. YeaZ of Gram-negative bacteria is a resuscitation promoting factor (Rpf) homologous protein could resuscitate bacteria of natural environment in VBNC state. To investigate the promoting effect of YeaZ on the isolation of viable but non-culturable (VBNC) bacteria from soil samples in extreme environments, the recombinant YeaZ of was prepared and added to the soil samples from volcanic soil and saline soil in Northwest China.

Expression and protease characterization of a conserved protein YgjD in .

The glycopeptidase GCP and its homologue proteins are conserved and essential for survival of bacteria. The gene (Glycopeptidase homologue) was cloned from strain SF-1. The gene consisted of 1,017 bp, which encodes a 338 amino acid polypeptide.
