Possible fetal bovine serum-reduced boost cultivation of DF-1 by supplementation with plant peptones and yeast extracts
To reduce the fetal bovine serum (FBS) and enhance the DF-1 proliferation, three plant peptones and three yeast extracts were incorporated into culture medium. The concentration of FBS in the medium varied from 0 to 10%, and the enhanced cell viability was evaluated within the predetermined range for supplementation. In each specific concentration range, the viability was enhanced by the supplementation compared to the control group. In particular, the medium containing 6.25 mg/mL wheat peptone and 1.25% FBS demonstrated a significant increase in viability. This beneficial effect can be attributed to the incorporation of suitable free amino acids (FAAs), peptides, carbohydrates (excluding free sugars), or trace elements through supplementation. Regarding FAAs, the enhanced cell proliferation by glutamate, glutamine, alanine, and non-essential FAAs was contingent upon the specific type of supplementation. The proliferation was suppressed by serine, histidine, threonine, arginine, tyrosine, valine, methionine, phenylalanine, isoleucine, leucine, essential FAAs, and particularly lysine.
期刊介绍：
The FSB journal covers food chemistry and analysis for compositional and physiological activity changes, food hygiene and toxicology, food microbiology and biotechnology, and food engineering involved in during and after food processing through physical, chemical, and biological ways. Consumer perception and sensory evaluation on processed foods are accepted only when they are relevant to the laboratory research work. As a general rule, manuscripts dealing with analysis and efficacy of extracts from natural resources prior to the processing or without any related food processing may not be considered within the scope of the journal. The FSB journal does not deal with only local interest and a lack of significant scientific merit. The main scope of our journal is seeking for human health and wellness through constructive works and new findings in food science and biotechnology field.
