Genetic investigation within Lactococcus garvieae revealed two genomic lineages.

abstract：:This communication presents experimental evidence that intact fragile (osmotic sensitive) yeasts can be electrofused and give viable hybrids. The yield increases with one order of magnitude for electrofusion of intact fragile yeasts with protoplasts of non-fragile ones. The yield of viable hybrids, obtained by electro...
