Endospores, prokaryotes, and microbial indicators in arable soils from three long-term experiments

Gram-positive bacteria control the rapid anabolism of protein-sized soil organic nitrogen compounds questioning the present paradigm

“…To test whether the substantial decomposition of the > 100 kDa organic N fraction in the Jyndevad soils can be attributed to soil specific conditions, we also incubated the Askov LTE soils with the protein-sized fraction (> 100 kDa). Soil from Askov is more clayey than the Jyndevad soils 21 (Table S1 and S2 ), and the LTE treatments have resulted in different microbial communities 31 , 32 and fertility levels 33 . The decomposition pattern of the > 100 kDa fraction across the fertility levels of the Askov soils resembled those observed among the different pH levels of the Jyndevad soils (Fig.…”

Cellular content of biomolecules in sub-seafloor microbial communities

“…For the amino sugar muramic acid (MA), freeze-dried sediment samples were hydrolyzed with 3 N HCl at 95 °C for 4 h under N 2 , and the analyses of the dissolved and filtered samples were performed according to Lomstein et al (2009). Concentrations of MA were corrected for losses during hydrolysis, which was 5.1% (Tamez-Hidalgo et al, 2016). During strong acid hydrolysis, acetyl groups are removed from amino sugars, but in this study we do not know whether the amino sugars were acetylated prior to hydrolysis.…”

Generalists and specialists decomposing labile and aromatic biochar compounds and sequestering carbon in soil

“…4), which have a wider niche and adapt to adverse environmental stresses (e.g. drought and heavy metals) (Gomez-Montano et al, 2013;Tamez-Hidalgo et al, 2016). Thus, we speculate that Sporosarcina survives in both C-rich and C-limited environments.…”
