Limonoid bacteria

Metabolism in Bacteria. Three species of bacteria, which are capable of metabolizing limonoids, have been isolated from soil by Hasegawa et al. (16,17,18,19), Table IV.

Biological Removal Six species of bacteria, each capable of metabolizing limonoids, have been isolated from soil by enrichment using limonoids as carbon sources. They are Arthrobacter globiformis (34), Pseudomonas 321-18 (35), Arthrobacter globiformis II (36), Bacterium 342-152-1, Corynebacterium fasclans (37) and Aclnetobacter sp. (38). Based on the metabolites and enzymes produced by these species of bacteria, five metabolic pathways of limonoids have been established in bacteria (3)(Fig. 4). 

The majority of scientific papers report the antimicrobial effects of different parts (peel, seed) of the fruit. Grapefruit peel extracts are effective especially against Gram positive bacteria. Similar activity has been reported for the limonoids of the seeds. In one experiment, a product containing grapefruit seed extract proved to be effective agaiirst several bacterial straiirs. This activity was ascribed to some qua-...
