An innovative inbuilt moving bed biofilm reactor (MBBR) was created to protect fish from nitrogen in a household aquarium. During the 90 experimental days, the ammonia nitrogen (NH4+-N) concentration in the aquarium with the inbuilt MBBR was always below 0.5 mg/L, which would not threaten the fish. Concurrently, nitrite and nitrate nitrogen concentrations were always below 0.05 mg/L and 4.5 mg/L, respectively. However, the blank contrast aquarium accumulated 1.985 mg/L NH4+-N on the 16th day, which caused the fish to die. The suspended biofilms could achieve the specific NH4+-N removal rate of 45.43 g/m3/d. Biofilms presented sparsely with filamentous structures and showed certain degrees of roughness. The bacterial communities of the suspended biofilms and the sediment were statistically different (p < 0.05), reflected in denitrifying and nitrifying bacteria. In particular, the relative abundance of Nitrospira reached 1.4%, while the genus was barely found in sediments. The suspended biofilms showed potentials for nitrification function with the predicted sequence numbers of ammonia monooxygenase [1.14.99.39] and hydroxylamine dehydrogenase [EC:1.7.2.6] of 220 and 221, while the values of the sediment were only 5 and 1. This study created an efficient NH4+-N removal inbuilt MBBR for household aquariums and explored its mechanism to afford a basis for its utilization.

“…Fusibacter spp. are thought to contribute to many important agroecosystem services including decomposition of SOM ( Qiu et al, 2021 ), heterotrophic denitrification ( Han F. et al, 2021 ), and arsenate/sulfate reduction ( Wang and Huang, 2021 ). Nocardioidaceae have previously been found to be among the most dominant phylotypes in wheat rhizospheres grown in Islamabad and Azad Jammu and Kashmir regions of Pakistan ( Latif et al, 2020 ), and noted for their potential PGP capabilities ( Yadav et al, 2017 ).…”

Diversity and functional traits of indigenous soil microbial flora associated with salinity and heavy metal concentrations in agricultural fields within the Indus Basin region, Pakistan

et al. 2022

Soil salinization and heavy metal (HM) contamination are major challenges facing agricultural systems worldwide. Determining how soil microbial communities respond to these stress factors and identifying individual phylotypes with potential to tolerate these conditions while promoting plant growth could help prevent negative impacts on crop productivity. This study used amplicon sequencing and several bioinformatic programs to characterize differences in the composition and potential functional capabilities of soil bacterial, fungal, and archaeal communities in five agricultural fields that varied in salinity and HM concentrations within the Indus basin region of Pakistan. The composition of bacteria with the potential to fix atmospheric nitrogen (N) and produce the enzyme 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase were also determined. Microbial communities were dominated by: Euryarchaeota (archaea), Actinobacteria, Proteobacteria, Planctomycetota, Firimicutes, Patescibacteria and Acidobacteria (bacteria), and Ascomycota (fungi), and all soils contained phylotypes capable of N-fixation and ACC-deaminase production. Salinity influenced bacterial, but not archaeal or fungal communities. Both salinity and HM altered the relative abundance of many phylotypes that could potentially promote or harm plant growth. These stress factors also appeared to influence the potential functional capabilities of the microbial communities, especially in their capacity to cycle phosphorous, produce siderophores, and act as symbiotrophs or pathotrophs. Results of this study confirm that farms in this region are at risk due to salinization and excessive levels of some toxic heavy metals, which could negatively impact crop and human health. Changes in soil microbial communities and their potential functional capabilities are also likely to affect several critical agroecosystem services related to nutrient cycling, pathogen suppression, and plant stress tolerance. Many potentially beneficial phylotypes were identified that appear to be salt and HM tolerant and could possibly be exploited to promote these services within this agroecosystem. Future efforts to isolate these phylotypes and determine whether they can indeed promote plant growth and/or carry out other important soil processes are recommended. At the same time, identifying ways to promote the abundance of these unique phylotypes either through modifying soil and crop management practices, or developing and applying them as inoculants, would be helpful for improving crop productivity in this region.

“…Members of the family Marinilabiliaceae possess a wide range of enzymatic activities, including cellulases, chitinases, lipases, and proteases (Kumar et al 2012;Liu et al 2014), which may enable them to degrade complex macromolecules, such as cellulose and chitin (Kumar et al 2012), making them important contributors to marine degradation processes. These features suggest that Marinilabiliaceae strains play crucial roles in various ecological processes, including their function to contribute to the cycling of organic matter (Inoue et al 2015), and nutrient dynamics in aquatic ecosystems, participating in the decomposition of complex organic compounds and the recycling of essential elements (Han et al 2021;Gao et al 2022). Additionally, genetic studies have revealed the presence of diverse metabolic pathways and secondary metabolite biosynthesis gene clusters in certain Marinilabiliaceae strains, such as Alkali exus imshenetskii (Detkova et al 2009), and most strains produce important metabolites such as propionate, acetate, and succinate , suggesting these strains could be developed as cell-factories to produce bioactive compounds in related industries.…”

A strictly anaerobic, motile bacterium, designated as strain Ai-910 T , was isolated from the sludge of an anaerobic digestion tank in China. Cells were Gramstain-negative rods. Optimal growth was observed at 38°C (growth range 25-42°C), pH 8.5 (growth range 5.5-10.5), and under a NaCl concentration of 0.06% (w/v) (range 0-2.0%). Major cellular fatty acids were iso-C 15 : 0 and anteiso-C 15 : 0 . The respiratory quinone was MK-7. Using xylose as the growth substrate, succinate was produced as the fermentation product. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain Ai-910 T formed a distinct phylogenetic lineage that re ects a new genus in the family Marinilabiliaceae, sharing high similarities to Alkali exus imshenetskii Z-7010 T (92.78%), Alkalitalea saponilacus SC/BZ-SP2 T (92.51%), and Geo lum rubicundum JAM-BA0501 T (92.36%). Genomic similarity (average nucleotide identity and digital DNA-DNA hybridization) values between strain Ai-910 T and its phylogenetic neighbors were below 65.27 and 16.90%, respectively, indicating that strain Ai-910 T represented a novel species. The average amino acid identity between strain Ai-910 T and other related members of the family Marinilabiliaceae were below 69.41%, supporting that strain Ai-910T was a member of a new genus within the family Marinilabiliaceae. Phylogenetic, genomic, and phenotypic analysis revealed that strain Ai-910 T was distinguished from other phylogenetic relatives within the family Marinilabiliaceae. The genome size was 3.10 Mbp, and the DNA G + C content of the isolate was 42.8 mol%.Collectively, differences of the phenotypic and phylogenetic features of strain Ai-910 T from its close relatives suggest that strain Ai-910 T represented a novel species in a new genus of the family Marinilabiliaceae, for which the name Xiashengella succiniciproducens gen. nov., sp. nov. was proposed. The type strain of Xiashengella succiniciproducens is Ai-910 T (= CGMCC 1.17893 T = KCTC 25304 T ).
