Acinetobacter tandoii ZM06 Assists Glutamicibacter nicotianae ZM05 in Resisting Cadmium Pressure to Preserve Dipropyl Phthalate Biodegradation

Abstract

Dipropyl phthalate (DPrP) coexists with cadmium as cocontaminants in environmental media. A coculture system including the DPrP-degrading bacterium Glutamicibacter nicotianae ZM05 and the nondegrading bacterium Acinetobacter tandoii ZM06 was artificially established to degrade DPrP under Cd(II) stress. Strain ZM06 relieved the pressure of cadmium on strain ZM05 and accelerated DPrP degradation in the following three ways: first, strain ZM06 adsorbed Cd(II) on the cell surface (as observed by scanning electron microscopy) to decrease the concentration of Cd(II) in the coculture system; second, the downstream metabolites of ZM05 were utilized by strain ZM06 to reduce metabolite inhibition; and third, strain ZM06 supplied amino acids and fatty acids to strain ZM05 to relieve stress during DPrP degradation, which was demonstrated by comparative transcriptomic analysis. This study provides an elementary understanding of how microbial consortia improve the degradation efficiency of organic pollutants under heavy metals contamination.

Halotolerant Terephthalic Acid-Degrading Bacteria of the Genus Glutamicibacter

“…The literature describes strains of the genus Glutamicibacter growing with phthalates and monoaromatic hydrocarbons as substrates. For instance, the strain G. nicotianae ZM05 is able to utilize OPA and phthalic acid esters: DBP, DMP, diethyl phthalate (DEP), di-n-propyl phthalate, and PCA [25]. The strain G. nicotianae MSSRFPD35 can degrade phenol and its derivatives, as well as catechol [26].…”
