solute and water activity effects on population growth phenotype population growth in high osmolarity phenotype 2017-02-20T15:58:54Z A population growth phenotype relating to the vegetative growth of a microbial population in conditions of high osmolarity, which refers to osmotic conditions where the osmolarity of the environment is higher than the osmolarity that allows for optimal population growth. Population growth may refer to growth rate, growth yield, or both. OMP:0007516 dsiegele microbial_phenotype
