TECHNOLOGY FOCUS - BIOLOGY - Preferred Method: The organic compounds are fermented to organic acids comprising at least lactic acid. The fermentation is an anaerobic fermentation. The fermentation is carried out a higher than 42 degrees C.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The organic compounds in the juice stream are present at a concentration of ( not greater than 5 wt./vol.%). Preferred Method: The organic acids, amino acids and other anions in the fermented juice stream are recovered by anion exchange without prior neutralization of pH, or after increasing the pH of the fermented juice stream. Prior to the fermentation of the juice stream, the juice stream is subjected to anion exchange at neutral or acidic pH for recovery of organic acids, amino acids and other anions; and further prior to the fermentation of the juice stream, the juice stream is subjected to cation exchange. The anions are eluted from the anion exchanger using ammonia. The ammonia is obtained from calcium hydroxide treatment of lignocellulosic material selected from at least one of a biogas fermentation digestate, waste water sludge and manure. The recovery of anions from the juice stream is performed at a site that is less than or equal to 10 km from the site where the lignocellulosic material is treated. Prior to ion exchange, protein is removed from the juice stream by at least one of heat coagulation and acid coagulation, and optionally decantation. EXAMPLE - Recovery of lactic acid from grass juice by ammonia elution, was carried out as follows. First to obtain a lactic acid solution (LAS), grass juice was prepared in a lab scale blender/press and heated to 95 degrees C to precipitate most proteins. Then it was cooled and kept at 50 degrees C in a jacketed vessel for 1 hour, with the addition of Lactobacillus, to ferment the sugars to lactic acid. During fermentation, the pH was kept above 5, by addition of NaOH. LAS (1.5 L) was then filtered, and then fed to the bottom of a column, filled with Amberlyst A21 (RTM: weak anion ion exchange resin) (100 g). Due to the upward direction of the flow, resin was mixed throughout the column and acted more as a mixed system than as a plug flow system. The resin was kept in the column with a screen at the top. The LAS flow rate of 10 ml/minute. After 1 hour, the LAS flow was stopped (but not drained) and the column was fed with gaseous NH3 at 500 ml/minute, for 15 minutes. At this rate, no gas escaped the column (confirmed by visual inspection only). The column was then drained to collect ammonium lactate solution (110 ml), and first sample (sample 1) was taken. Then the column was filled with water (100 ml), and drained again (sample 2), and filled with water (100 ml) and drained again (sample 3). Then, the column was filled with water (100 ml), and fed with gaseous NH3 at 500 ml/minute for another 15 minutes. The column was drained to collect ammonium lactate (sample 4). All four samples where analyzed for lactate content by HPLC method (with Aminex A6 (RTM: chromatography column) with 0.01 N H2SO4 as eluent (1 ml/minute) and UV detector, 214 nm). The lactate concentration (g/l) in samples 1, 2, 3 and 4 was found to be 125, 20, 5, and 55, respectively.
