Growth factor requirements of ruminal cellulolytic bacteria isolated from microbial populations supplied diets with or without rapidly fermentable carbohydrate.
The predominant cellulolytic ruminal bacteria isolated from microbial populations supplied diets containing cellulose as an energy source and essentially devoid of amino acids or rapidly fermentable carbohydrates were shown to require branched-chain acid(s) for growth.
