Abstract
Use of probiotic technology to support tanners to reduce waste and increase the value of by-products reducing the need of synthetic chemicals, improving the quality of effluents and reducing the carbon footprint to the environment. Probiotics or beneficial microorganisms are used to obtain biochemicals through a controlled fermentation of natural ingredients. The result of the process is a consortium of metabolites including viable probiotic microorganisms with properties very similar to traditional leather auxiliaries extensively needed during leather production, eliminating or reducing the need for use of toxic chemicals and compositions.
Claims18
A probiotic biochemical composition comprising a microorganism fermentation broth with a defined fingerprinting profile from metagenomics and metabolomics analysis, said probiotic biochemical composition comprising:
- Total Lactic Acid Bacteria counts of between 1.0E+4 to 1.0E+6 CFU/mL;
- Purple sulfur bacteria;
- and
- being essentially free of pathogenic or putrefactive microorganisms,
- wherein said fermentation broth is obtained by fermentation of probiotic microorganisms in a medium under defined fermentation conditions;
- wherein said probiotic biochemical composition has a pH value of <4.0 with activity in pH range from 2 to 12, percent total acidity between about 0.6 and about 3.2, and an Emulsification Index value between about 40% and about 75%.
A method of reducing sodium sulfide in the production of leather products, said method comprising unhairing an animal hide by contacting the hide with lime, a probiotic biochemical composition, and an amount of sodium sulfide for an effective period of time to release hair from said hide, wherein the amount of sodium sulfide used in said contacting, is reduced by at least 30%, said probiotic biochemical composition comprising:
- a microorganism fermentation broth with a defined fingerprinting profile from metagenomics and metabolomics analysis;
- Total Lactic Acid Bacteria counts of between 1.0E+4 to 1.0E+6 CFU/mL;
- Purple sulfur bacteria;
- and
- being essentially free of pathogenic or putrefactive microorganisms,
- wherein said fermentation broth is obtained by fermentation of probiotic microorganisms in a medium under defined fermentation conditions;
- wherein said probiotic biochemical composition has a pH value of <4.0 with activity in pH range from 2 to 12, percent total acidity between about 0.6 and about 3.2, and an Emulsification Index value between about 40% and about 75%.
