[0083] DHLA batch fermentation method (batch mode)

[0084] (1) A 48-hour inoculum culture was prepared from stock cultures of Lactobacillus casei and Lactobacillus fermentum as follows.

[0085] (1a) Lactobacillus casei inoculum preparation:

[0086] Forty-eight hours prior to the mixing start date, the L. casei inoculum was prepared. Ten (10) grams of stock (0022) freeze-dried 10 billion CFU / g Lactobacillus casei (from Nebraska Cultures, Inc.) was added to Edge Biologicals in Memphis, TN. Co., Ltd. Catalog No. B-0965 (Edge Biologicals, Inc. Catalog No. B-0965 Memphis, TN) provided 500mL MRS fermentation broth. The inoculum was incubated at 37°C in an atmosphere of 90% N2:5% CO2:5% O2. After 48 hours of incubation, 500 mL of the inoculum was washed twice with phosphate buffered saline using a centrifuge. The washed pellet was then reconstituted with a total of 100 mL of phosphate buffer and combined into one vessel to inoculate the DHLA fermentation batch.

Abstract

A process for production and extraction of dihydrolipoic acid (DHLA) relates to the biotransformation of R-lipoic acid to dihydrolipoic acid. The process ferments the lipoic acid with bacteria selected from the genus of any of the following bacteria: Lactobacillus, Enterococcus, Pediococcus, or Bacillus. More particularly the present invention relates to a method for the extraction of DHLA utilizing a non-traditional solvent system, namely a food oil. Generally the DHLA that is produced in the present method is isolated from cells which have been inactivated or killed.

Description

technical field [0001] The present invention relates to the biotransformation of R-lipoic acid to dihydrolipoic acid (DHLA). The method ferments lipoic acid with bacteria selected from any of the following bacterial genera: Lactobacillus, Enterococcus, Pediococcus or Bacillus. More specifically, the present invention relates to methods for extracting DHLA using non-traditional solvent systems (ie, food oils). Typically, DHLA produced in the methods of the invention is isolated from cells that have been inactivated or killed. Background technique [0002] Dihydrolipoic acid is a valuable nutrient. Its production and isolation are made difficult by its ease of oxidation to its disulfide form (ie, lipoic acid) under a variety of standard conditions. [0003] DHLA is typically produced in vivo during normal metabolic activity through the redox conversion of lipoic acid or alpha-lipoic acid (ALA). However, the body usually only produces enough DHLA to aid in metabolic functio...
