TL;DR: This research highlights the need to understand more fully the role of “spatially aggregated immune checkpoints” in the development of central nervous systems.

TL;DR: In this paper , the metabolic fates and response strategies of microorganisms to aromatic compounds with different structures (phenol, naphthalene, phenanthrene, and pyrene) were comparatively studied.
Abstract: In this study, the metabolic fates and response strategies of microorganisms to aromatic compounds with different structures (phenol, naphthalene, phenanthrene, and pyrene) were comparatively studied. The results indicated that the phenol (90.9%), naphthalene (68.4%), phenanthrene (69.5%), and pyrene (67.1%) could be mineralized, and the biotoxicity also has been drastically reduced. The degradation characteristics and toxic effects were closely related to their chemical structure. The microorganisms showed different response strategies to aromatic compounds with different structures. Phenol had a simple structure and low toxicity, the microbial community structure was simple, and the rapid expression of key enzymes enabled it to be rapidly degraded. For the hydrophobic and complex naphthalene, phenanthrene, and pyrene, the more complex the structure, the higher the microbial diversity, the EPS showed different response for the purpose of improving their bioavailability, and the activity of key enzymes was positively correlated with their structural complexity.

Abstract: The polycyclic aromatic hydrocarbons (PAHs) pollution to the environment is a major threat to the living organisms, and hence the degradation of these PAHs is necessary. Studies on PAHs degrading bacteria have focussed on terrestrial microbes and the potential of marine derived microbes is undermined. Herein we report the isolation and characterization of PAHs degrading Burkholderia sp. from lagoon sediments collected at the Southern coast of India. The strain was Gram negative, rod-shaped, motile, and ∼2–5 μm in length. Based on the phylogenetic data the strain was identified as Burkholderia and designated as VITRSB1. Initial PAHs degradation ability of the strain was assessed using basal salt medium supplemented with diesel, kerosene, toluene, aniline, naphthalene, and phenol. The strain was found to be effectively degrading kerosene, diesel, toluene, and aniline even at higher concentration (1%). However, naphthalene and aniline were degraded only at lower concentration (0.1%) and phenol, camphor, and DAP inhibited the growth of the strain. Furthermore, the degraded end products of the PAHs were determined using FTIR. Notably, none of the end products were found to be toxic to the biosphere. Our results indicate that the isolated Burkholderia sp. could be a prospective candidate for the effective degradation of selective PAHs.
