Anionic trehalose lipids

TABLE 1 Characteristic Data on the Microbial Production of Rhamnose Lipids (RLs), Trehalose Corynomycolates (TL-Cs), and Anionic Trehalose Lipids (TLs), Respectively... 

An anionic trehalose lipid was first documented in 1981 from Mycobacterium paraffinicum. Two years later a similar product, 2-0-succinoyl-3,4,2 -tri-0-acyl-a,a-D-trehalose (Fig. 5, bottom) was found culturing Rhodococcus erythropolis DSM 43215 under nitrogen-limiting conditions [28]. After optimization of the process more than 30 g/L of trehalose lipids could be isolated (Table 1) [29]. In addition, similar monosuccinoyl and disuccinoyl trehalose lipids have been reported from another R. erythropolis strain, SD-74 [30,31].
