“…In addition, there were also some microbial composition shifts that were neither the biomarker of the sole biochar‐treated group or biochar‐fertilizer group, such as the bacterial phylum Thaumarchaeota. This taxon showed a preference for high soil carbon content (Xie et al, 2015), which was introduced into the soil by biochar addition.…”

“…In addition, bacterial phylum Thaumarchaeota , Cyanobacteria , and Planctomycetes were also positively correlated with soil nutrient content involving in nutrient cycling, which is in accordance with other studies (Ren et al, 2018a). For example, some studies showed that Thaumarchaeota played an important role in soil nitrogen cycling, that is, ammonia oxidizing (Pester et al, 2011; Xie et al, 2015). All of these bacterial groups acted as the main responsible microorganisms for soil nutrient increase in biochar‐treated soils, especially biochar‐based fertilizer‐treated soil.…”

Biochar‐based fertilizer treatments induced significant microbial community structure shifts compared with no‐biochar and biochar alone. Biochar‐based fertilizer especially at higher biochar addition rate increased soil microbial biomass and fertility. Soil microbial species were strongly correlated with soil nutrients under biochar and biochar‐based fertilizer into karst soil. Karst ecosystems are vulnerable to degradation and constitute a significant proportion of southwestern China. Here, we explore the amendment of these soils with wood biochar in combination with N‐P‐K fertilizer and swine manure compost with the goal of improving microbial community structure and soil nutrient status of these soils. A pot experiment with six treatments, including control (CK, no amendment), swine manure compost plus N‐P‐K fertilizer (MF), wood biochar at 2% in soil (W2), wood biochar at 4% in soil (W4), wood biochar‐based fertilizer at 2% in soil (W2MF), and biochar‐based fertilizer at 4% in soil (W4MF), was set up for 20 months. The results showed that soil organic matter and soil available nutrients N, P, and K in W4MF increased by 63.95, 66.23, 284.96, and 94.56%, respectively, compared with CK. Soil microbial biomass C, N, and P increased in sequence by 60.05, 87.64, and 307.85%, respectively. Soil bacterial and fungal diversity indices (Simpson and Shannon) and richness index (Chao1) were generally higher in biochar‐based fertilizer treatments (W2MF and W4MF) than biochar alone (W2 and W4). The bacterial and fungal community structures of biochar based fertilizer treatments differed from those of biochar amendment alone or control (P < 0.05). Linear discriminant (Effect Size) analysis showed that the bacterial biomarkers of the W2MF + W4MF group were mainly the phylum Acidobacteria and class Alphaproteobacteria, and the fungal biomarkers were the phylum Rozellomycota and Glomeromycota. Redundancy analysis revealed strong relationships between microbial community structure and soil organic matter and soil available nutrients N, P, and K (P < 0.05). In conclusion, either sole biochar or biochar‐based fertilizer amendment improved karst soil nutrient conditions and induced microbial community structural shifts. The performance was better in biochar‐based fertilizer treatment than that in biochar addition alone.

“…Thermoplasmatales constituted a major proportion of archaeal populations in eight upland soils ( Figure 5A and Supplementary Table S1 ), which is consistent with results from Hu et al (2013) ; methanogens were observed in large abundance in 10 samples from rice fields, river surface sediments and wet land ( Figure 5B and Supplementary Table S1 ), which are also the case in the previous studies ( Hu et al, 2013 ; Beckmann and Manefield, 2014 ; Ke et al, 2014 ; Liu D. et al, 2014 ; Mach et al, 2015 ). Additionally, one of the upland soil sites in CM was examined for estimating the monthly changes in archaeal community between March 2012 and March 2013 ( Xie et al, 2015 ). Methanogens, Thermoplasmata, Group I.1b (Nitrososphaera) and YLA114 were dominant in the archaeal populations, which had the maximum dissimilarity in relative abundance less than 6% among different months ( Xie et al, 2015 ).…”

This suggests that the change in archaeal community is not significant among different months, which can be interpreted by that the response of archaeal community DNA structures to environmental change is reduced by their capabilities of the high functional and genetic diversity, rapid evolutionary rate and great dispersal ( Prosser et al, 2007 ; Cruz-Martínez et al, 2009 ).…”

Thermoplasmatales and Methanogens: Potential Association with the Crenarchaeol Production in Chinese Soils

Crenarchaeol is a unique isoprenoid glycerol dibiphytanyl glycerol tetraether (iGDGT) lipid, which is only identified in cultures of ammonia-oxidizing Thaumarchaeota. However, the taxonomic origins of crenarchaeol have been debated recently. The archaeal populations, other than Thaumarchaeota, may have associations with the production of crenarchaeol in ecosystems characterized by non-thaumarchaeotal microorganisms. To this end, we investigated 47 surface soils from upland and wetland soils and rice fields and another three surface sediments from river banks. The goal was to examine the archaeal community compositions in comparison with patterns of iGDGTs in four fractional forms (intact polar-, core-, monoglycosidic- and diglycosidic-lipid fractions) along gradients of environments. The DistLM analysis identified that Group I.1b Thaumarchaeota were mainly responsible for changes in crenarchaeol in the overall soil samples; however, Thermoplasmatales may also contribute to it. This is further supported by the comparison of crenarchaeol between samples characterized by methanogens, Thermoplasmatales or Group I.1b Thaumarchaeota, which suggests that the former two may contribute to the crenarchaeol pool. Last, when samples containing enhanced abundance of Thermoplasmatales and methanogens were considered, crenarchaeol was observed to correlate positively with Thermoplasmatales and archaeol, respectively. Collectively, our data suggest that the crenarchaeol production is mainly derived from Thaumarchaeota and partly associated with uncultured representatives of Thermoplasmatales and archaeol-producing methanogens in soil environments that may be in favor of their growth. Our finding supports the notion that Thaumarchaeota may not be the sole source of crenarchaeol in the natural environment, which may have implication for the evolution of lipid synthesis among different types of archaea.

“…These Archaea are known to be present in the soil (e.g. Leininger et al 2006;Xie et al, 2015) but have yet to be investigated in karst vadose zone or groundwater. Globally, crenarchaeol abundance in soil increases with soil pH (Weijers et al, 2006;Cao et al, 2012) and decreases in abundance with depth (Cao et al, 2012), and Thaummarchaeota have been observed…”
