Novel sialidase from non-pathogenic bacterium strain O129.

Bacterial sialidases are enzymes that are involved in a number of vital processes in microorganisms and in their interaction with the host or the environment. Their wide application for scientific and applied purposes requires the search for highly effective and non-pathogenic producers. Here, we report the first description of sialidase from .

Rapid screening of plasmid-encoded small hsp-genes in Streptococcus thermophilus.

A new rapid procedure for detection of small heat shock protein genes (shsp) was developed. Using PCR-based molecular approach, single colonies of 49 Streptococcus thermophilus industrial and artisanal starters were examined. Five strains contained plasmid-encoded shsp.
