Differentiation of Candida guilliermondii varieties by lectin-like substances from marine algae.

abstract：:Soil is one of the most complex and challenging environments for microbiologists. In fact, although it contains the largest microbial diversity on the planet, the majority of these microbes are still uncharacterized and represent an enormous unexplored reservoir of genetic and metabolic diversity. Metagenomics, the st...
