“…For organic growing systems, reliance on organic matter as the main method of building soil health was associated with a greater biomass and greater diversity of bacteria, fungi, actinomycetes, and soil invertebrates such as earthworms, in comparison with conventional farming. Higher soil respiratory and enzyme activities were also observed (van Bruggen and Termorshuizen 2003;Pimentel et al 2005;Purin et al 2006;Dorais 2007;Lee 2010;Ge et al 2011). These benefits resulted in some cases in higher yields than conventional farming provided (Table 4.7).…”

“…Ge et al (2011) mencionam que o aumento da eficiência metabólica de uma comunidade microbiana pode ser refletido pela sua taxa de respiração. A ocorrência de uma taxa respiratória elevada no solo da mata indica atividade microbiana elevada, estimulada por microorganismos heterotróficos, pela adição permanente e contínua de matéria orgânica ao solo (Moeskopset al, 2010).…”

“…Moreira & Siqueira (2006) relatam que na seleção de indicadores de qualidade de solo é importante associar os atributos físicos, químicos e biológicos, com o intuito de avaliar o impacto de determinada atividade agrícola. Por sua vez, Ge et al (2011) consideram que a atividade microbiana seja sensível às atividades antrópicas em relação aos atributos físicos e químicos e, portanto, são considerados indicadores de importância visando avaliar o impacto e sustentabilidade da atividade agrícola.…”

“…Of the physicochemical properties measured, the multivariate statistical analysis showed that the major influence on cbbL gene diversity and, by inference, on soil bacterial autotrophs is SOC. Soil organic matter is the most active fraction in soil and is a key determinant of soil fertility and productivity (9,25,42). SOC also stabilizes soil structure (7) and is an important source of carbon for microbial growth and of nutrients such as phosphorus, sulfur, calcium, magnesium, and trace elements (30).…”

ABSTRACTSoils were incubated for 80 days in a continuously labeled14CO2atmosphere to measure the amount of labeled C incorporated into the microbial biomass. Microbial assimilation of14C differed between soils and accounted for 0.12% to 0.59% of soil organic carbon (SOC). Assuming a terrestrial area of 1.4 × 108km2, this represents a potential global sequestration of 0.6 to 4.9 Pg C year−1. Estimated global C sequestration rates suggest a “missing sink” for carbon of between 2 and 3 Pg C year−1. To determine whether14CO2incorporation was mediated by autotrophic microorganisms, the diversity and abundance of CO2-fixing bacteria and algae were investigated using clone library sequencing, terminal restriction fragment length polymorphism (T-RFLP), and quantitative PCR (qPCR) of the ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO) gene (cbbL). Phylogenetic analysis showed that the dominantcbbL-containing bacteria wereAzospirillum lipoferum,Rhodopseudomonas palustris,Bradyrhizobium japonicum,Ralstonia eutropha, andcbbL-containing chromophytic algae of the generaXanthophytaandBacillariophyta. Multivariate analyses of T-RFLP profiles revealed significant differences incbbL-containing microbial communities between soils. Differences incbbLgene diversity were shown to be correlated with differences in SOC content. Bacterial and algalcbbLgene abundances were between 106and 108and 103to 105copies g−1soil, respectively. BacterialcbbLabundance was shown to be positively correlated with RubisCO activity (r= 0.853;P< 0.05), and bothcbbLabundance and RubisCO activity were significantly related to the synthesis rates of [14C]SOC (r= 0.967 and 0.946, respectively;P< 0.01). These data offer new insights into the importance of microbial autotrophy in terrestrial C cycling.
