These metabolites are dialysable, volatile and inactivated by ether and by chloroform. They are active in solid media for a long time after excretion. These properties are like those of the negative chemotaxic metabolites that have been held responsible for the swarming of proteus organisms. These metabolites do not influence parallelstreak tests for syntrophism between auxotrophs of P. mirabilis. %U https://www.microbiologyresearch.org/content/journal/jmm/10.1099/00222615-5-2-191
