Nu-Tek Bioscience Announces study comparing various Soy and Pea Peptones and Yeast extracts on Nov. 14, 2016

Minnetonka, MN, 2016-Nov-14 — /EPR Biotech News/ — Today at Nu-Tek Bioscience announced the completion of an outside study comparing various protein sources on the enhancement of Cell growth using E. Coli. The study was completed by The University of St. Thomas.

Nu-Tek HSP (Hydrolyzed Soy Protein) and HPP (Hydrolyzed Pea Protein) peptones showed the least strain dependent variability in growth performance. In contrast to competitor peptones showed poorer performance. This has been an ongoing issue with media developers to minimize the variation from lot to lot in Peptones. Nu-Tek Bioscience has developed a technology that promotes reduction in variability.

Blending HPP (Nu-Tek’s Bioscience Hydrolyzed Pea Protein) with a weakly performing peptone supports growth of the weakly performing peptone to the level of performance of the HPP alone. The study has shown excellent growth performance results that compare favorably with soy peptones, pea peptones and yeast extracts. In addition, peptones have been shown to improve fermentations versus yeast extract “only” growth media.
