Abstract
There is disclosed a process for the recovery of an insoluble fermentation product from a solid phase cell mass, the process comprising treating the fermentation broth to solubilize the cell mass and separating by known methods the liquid phase from the insoluble (product-containing) phase. The solubilization of the cell mass may be carried out by one or more treatments with an alkali or acid compound or by enzymatic treatment of the cell mass to lyze the cells.
Claims
1. A recovery process useful for recovering an insoluble fermentation product from an aqueous fermentation broth comprising a first solid phase containing the insoluble fermentation product and a second solid phase containing cell mass, the process comprising: a) treating the aqueous fermentation broth one or more times with either an appropriate alkali or an appropriate acid at a temperature over room temperature for a period of time sufficient to solubilize at least about 20% of cell mass, resulting in an aqueous fermentation broth containing the first solid phase containing the insoluble fermentation product; and b) separating the first solid phase containing the insoluble fermentation product from the aqueous fermentation broth; and c) recovering the insoluble fermentation product from the first solid phase.
2. A process of Claim 1 wherein the alkali is selected from the group consisting of potassium hydroxide, sodium hydroxide and ammonia.
3. A process of Claim 1 wherein the acid is selected from the group consisting of phosphoric acid, sulfuric acid, hydrochloric acid, nitric acid and perchloric acid.
4. A process of Claim 1 wherein the temperature is from about 40 to 100°C.
5. A process of Claim 4 wherein the temperature is from about 90-95cC.
6. A process of Claim 1 wherein the aqueous fermentation broth is contacted with each appropriate alkali or acid for a period of from about 1 to 12 hours.
7. A process of Claim 1 further comprising resuspending one or more times the first solid phase resulting from step a) with either an appropriate alkali or an appropriate acid to solubilize residual, unsolubilized cell mass in the first solid phase prior to recovering the insoluble fermentation product.
8. A process of Claim 1 wherein the desired insoluble fermentation product is indigo, melanin or glucan.
9. A process of Claim 1 wherein the second solid phase is solubilized by enzymatic treatment of the cell mass.
10. A process of Claim 9 wherein the enzyme is selected from the group consisting of lysozyme, protease, DNase, RNase or a combination thereof.
11. A process for the recovery of indigo from an aqueous fermentation broth comprising a first solid phase containing indigo and a second solid phase containing cell mass, the process comprising: a) contacting the fermentation broth with an appropriate alkali selected from the group consisting of potassium hydroxide, sodium hydroxide and ammonia at a temperature of from about 40 to 100°C for a period of time sufficient to solubilize at least about 20% of cell mass; b) separating the first solid phase containing indigo from the aqueous broth; c) optionally resuspending the first solid phase containing indigo with either an appropriate alkali selected from the group consisting of potassium hydroxide, sodium hydroxide and ammonia or an appropriate acid selected from the group consisting of phosphoric acid, sulfuric acid, hydrochloric acid, nitric acid and perchloric acid at a temperature of from about 40 to 100°C for an appropriate period of time to solubilize residual insoluble cell mass; d) separating the first solid phase from the aqueous broth; and e) recovering the indigo from the first solid phase.
12. A process of Claim 11 wherein the alkali is sodium hydroxide and the acid is phosphoric acid.
13. A process of Claim 11 wherein the temperature is from about 90-95°C.
14. A process of Claim 13 wherein each alkali and acid step is carried out for a period of from about 1 to 12 hours.
15. A process of Claim 11 further comprising purifying the indigo product resulting from such recovery process.
16. The process of Claim 1 further comprising purifying the indigo recovered from said process.
17. The process of Claim 7 further comprising purifying the indigo recovered from said process.
