Growth factor requirements of ruminal cellulolytic bacteria isolated from microbial populations supplied diets with or without rapidly fermentable carbohydrate. (1/1)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.

I'm not a medical professional, but I can tell you that "biuret" is a chemical compound with the formula NH~2~(CONH)~2~CONH~2~. It contains two urea molecules connected by a central carbonyl group. Biuret is formed as a byproduct in the industrial production of urea, and it can also be produced in the metabolism of certain medications.
In medical contexts, "biuret" may refer to a biuret test, which is a chemical test used to detect the presence of proteins in a solution. The biuret test is based on the ability of biuret to form a colored complex with copper ions in an alkaline solution. Proteins contain peptide bonds that can react similarly to biuret, forming a purple-colored complex when combined with copper ions and an alkaline solution. Therefore, the presence of this color indicates the presence of proteins in the solution.
However, "biureas" is not a recognized medical term or concept. It's possible that you may have misspelled or misremembered the term, so I would recommend double-checking your source to ensure accuracy.
