“…In this study, enhanced PN and PS formations were obtained under increasing quinoline and phenol loadings, which might facilitate stronger cell aggregations by changing the surface charge and/or hydrophobicity of microbial cells and forming polymeric matrix (More et al, 2014). Similar observations have been reported in previous biofilm reactors (Zheng et al, 2016;He et al, 2021b), such as 2− 5 times higher concentrations of PS and PN when increasing phenol concentrations from 10 to 100 mg/L in an aerobic granular reactor (He et al, 2021b). Furthermore, the predominance of PN in LB-EPS (43.0 ± 6.9%) than in TB-EPS (24.9 ± 9.9%) (Fig.…”

“…2a) would promote cell adhesion in the outer region and efficient biofilm formation by increasing cell surface hydrophobicity and charge (Wingender et al, 1999). The significant increase in TB-PS under additional spike of pyridine and phenol during P6-P9 would strengthen structure and stability of biofilms due to its viscous and hydrophilic properties (He et al, 2021b;Hou et al, 2015). To confirm the respective contribution of EPS content to cell adhesion and aggregation within biofilms, additional adhesion and aggregation tests combined with surface characteristics and in-depth analysis of EPS compositions using nuclear magnetic resonance technique and three-dimensional excitation-emission matrix fluorescence spectroscopy are needed in future studies.…”

“…Phenol is a kind of typical xenobiotic compound, and the predicted function of "xenobiotics biodegradation and metabolism" is relevant to xenobiotic degradation (Tian et al 2020). In previous studies, with the increase in phenol concentration, the xenobiotic degradation function was improved (He et al 2021;Tian et al 2020;Wu et al 2019). In this study, xenobiotic degradation function declined over 30 days in river sediments as phenol was eliminated.…”

Phenol is widely used in industrial processes and has microbial toxicity. However, the effects of a phenol spill on the microbial community are not clear. The present study explored the changes of bacterial communities in river and fish pond sediments after a phenol spill. The bacterial richness and diversity in river sediments were lower on day 30 (36 days after the spill) than on day 0, while they increased in fish pond sediments. The structures and functions of bacterial communities in both river and fish pond sediments were changed, and a more dramatical variation was detected in fish pond sediments. In river sediments, Proteobacteria, Chloroflexi, Acidobacteria, Bacteroidetes, and Nitrospirae were the major bacterial phyla, and Chloroflexi was enriched. In fish pond sediments, genera Brevibacillus dominated bacterial communities initially, and bacterial composition showed a dramatic change on day 30. Most predicted metabolism functions, as well as genetic information processing functions of translation, replication, and repair, were enhanced in both river and fish pond sediments, while they showed an opposite change trend for xenobiotic degradation function. This work could strengthen our understanding of the effects of phenol spills on sediment bacterial communities in both lotic and lentic ecosystems.

Cellular differentiation into hyphae and spores in halophilic archaea

et al. 2023

Several groups of bacteria have complex life cycles involving cellular differentiation and multicellular structures. For example, actinobacteria of the genus Streptomyces form multicellular vegetative hyphae, aerial hyphae, and spores. However, similar life cycles have not yet been described for archaea. Here, we show that several haloarchaea of the family Halobacteriaceae display a life cycle resembling that of Streptomyces bacteria. Strain YIM 93972 (isolated from a salt marsh) undergoes cellular differentiation into mycelia and spores. Other closely related strains are also able to form mycelia, and comparative genomic analyses point to gene signatures (apparent gain or loss of certain genes) that are shared by members of this clade within the Halobacteriaceae. Genomic, transcriptomic and proteomic analyses of non-differentiating mutants suggest that a Cdc48-family ATPase might be involved in cellular differentiation in strain YIM 93972. Additionally, a gene encoding a putative oligopeptide transporter from YIM 93972 can restore the ability to form hyphae in a Streptomyces coelicolor mutant that carries a deletion in a homologous gene cluster (bldKA-bldKE), suggesting functional equivalence. We propose strain YIM 93972 as representative of a new species in a new genus within the family Halobacteriaceae, for which the name Actinoarchaeum halophilum gen. nov., sp. nov. is herewith proposed. Our demonstration of a complex life cycle in a group of haloarchaea adds a new dimension to our understanding of the biological diversity and environmental adaptation of archaea.
