Preservation of Rhizobium viability and symbiotic infectivity by suspension in water.

abstract：:The neutral red (NR) cell viability assay was used with various cell types of human origin to quantitate the potency of T-2 mycotoxin and its metabolites. The human melanoma SK-Mel/27 cell line was the most sensitive, with a midpoint cytotoxicity value of 2.8 ng of T-2 per ml. With the human hepatoma cell line, HepG2,...
