Comparison of Yeast Growth in Mesquite Wood Hydrolysate

Abstract

Hot-water extracts of mesquite (Prosopis glandulosa) wood were assayed for their total carbohydrate, reducing sugar, and glucose content. These hydrolysates were then used as complete media for yeast growth. A total of 10 strains of yeasts were evaluated for their biomass production in the mesquite wood hydrolysates. Levels of utilizable carbohydrate proved to be the limiting factor for yeast growth in the hydrolysates.

“…D-Glucose was used as the standard in calibrating the preceding tests. Protein content was determined by the dye-binding technique of Bradford (1976) using 0.5 mL of sample and 4.5 mL of Coomassie Blue G-250 reagent (Stanlake, 1986), with bovine serum albumin (Dade Diagnostic, Inc., Aquado, Puerto Rico) serving as the standard.…”
