Biomass (e.g., plant biomass, animal biomass, microbial, and municipal waste biomass) is processed to produce useful products, such as food products and amino acids. 1. A method of producing a polyester polymer comprising:(i) saccharifying biomass to form a saccharified biomass;(ii) contacting the saccharified biomass with a microorganism to produce one or more products; and(iii) converting the one or more products to the polyester polymer.2. The method of claim 1 , wherein the polyester polymer comprises poly(lactic acid).3. The method of claim 1 , wherein the one or more products comprises an organic acid.4. The method of claim 3 , wherein the organic acid comprises lactic acid.5. The method of claim 1 , wherein the microorganism comprises a lactic acid bacteria (LAB).6Lactobacillus.. The method of claim 1 , wherein the microorganism comprises a species in the genera7. The method of claim 1 , further comprising treating the biomass prior to step (i) to reduce its recalcitrance.8. The method of claim 7 , wherein the treating comprises size reduction (e.g. claim 7 , mechanical size reduction of individual pieces of biomass) claim 7 , radiation claim 7 , sonication claim 7 , pyrolysis claim 7 , or oxidation9. The method of claim 7 , wherein the treating comprises radiation claim 7 , e.g. claim 7 , using ionizing radiation.10. The method of claim 7 , wherein the recalcitrance of the biomass is reduced by at least about 10%.11. The method of claim 7 , wherein the recalcitrance of the biomass is reduced by 50%-90%.12. The method of claim 1 , wherein the biomass is a lignocellulosic or cellulosic material.13.
