Abstract
Compositions of peptides and surface-active agents are described, as are methods of making and using such compositions. The compositions are capable of affecting metabolic rates in biological systems, and to accelerate nutrient uptake without a concomitant increase in biofilm production.
Claims21
A method for accelerating nutrient uptake in bacteria without a substantially commensurate increase of biomass, comprising contacting said bacteria with a mixture of an aerobic yeast fermentation supernatant and a surface-active agent, whereby the nutrient uptake in said bacteria is increased without a substantially commensurate increase of biomass,
- wherein the mixture of the aerobic yeast fermentation supernatant and the surface-active agent is obtained by:
- fermenting under aerobic conditions a plurality of yeast cells in the presence of a nutrient source,
- heating the plurality of yeast cells after the fermenting step to obtain a fermentation product,
- centrifuging the fermentation product to obtain the aerobic fermentation supernatant containing peptides, and
- combining the aerobic fermentation supernatant with the surface-active agent.
A method for accelerating nutrient uptake in bacteria or yeast without a substantially commensurate increase in biofilm production, comprising contacting said bacteria or yeast with a mixture of a aerobic yeast fermentation supernatant and a surface-active agent, whereby the nutrient uptake in said bacteria is increased without a substantially commensurate increase in biofilm production,
- wherein the mixture of the aerobic yeast fermentation supernatant and the surface-active agent is obtained by:
- fermenting under aerobic conditions a plurality of yeast cells in the presence of a nutrient source,
- heating the plurality of yeast cells after the fermenting step,
- centrifuging the fermentation product to obtain the aerobic fermentation supernatant containing peptides, and
- combining the aerobic fermentation supernatant with the surface-active agent.
