    <title language="eng">Effect of temperature change on the composition of the bacterial and archaeal community potentially involved in the turnover of acetate and propionate in methanogenic rice field soil</title>
    <abstract language="eng">The microbial community structure was investigated together with the path of methane production in Italian rice field soil incubated at moderate (35 °C) and high (45 °C) temperature using terminal restriction fragment length polymorphism and stable isotope fractionation. The structure of both the archaeal and bacterial communities differed at 35 °C compared with 45 °C, and acetoclastic and hydrogenotrophic methanogenesis dominated, respectively. Changing the incubation of the 45 °C soil to different temperatures (25, 30, 35, 40, 45, 50 °C) resulted in a dynamic change of both microbial community structure and stable isotope fractionation. In all treatments, acetate first accumulated and then decreased. Propionate was also transiently produced and consumed. It is noteworthy that acetate was also consumed at thermophilic conditions, although archaeal community composition and stable isotope fractionation indicated that acetoclastic methanogenesis did not operate. Instead, acetate must have been consumed by syntrophic acetate oxidizers. The transient accumulation and subsequent consumption of acetate at thermophilic conditions was specifically paralleled by terminal restriction fragments characteristic for clostridial cluster I, whereas those of clostridial clusters I and III, Acidaminococcaceae and Heliobacteraceae, paralleled the thermophilic turnover of both acetate and propionate.</abstract>

    <title language="eng">Soil type links microbial colonization of rice roots to methane emission</title>
    <abstract language="eng">Most of the methane (CH4) emission from rice fields is derived from plant photosynthates,
which are converted to CH4. Rice cluster I (RC-1) archaea colonizing the
rhizosphere were found to be the methanogens responsible for this process. Hence, RC-1
methanogens seem to play a crucial role in emission of the greenhouse gas CH4. We
determined the community composition and activity of methanogens colonizing the
roots of eight different rice cultivars after growth on both Italian rice soil and river bank
soil, which contained different communities of methanogenic archaea. The community
composition was analyzed by terminal restriction fragment length polymorphism and
cloning/sequencing of the archaeal 16S rRNA gene and the mcrA gene coding for a
subunit of the methyl coenzyme M reductase. When grown on rice field soil, the
methanogenic community of the different rice cultivars was always dominated by RC-1
methanogens. In contrast, roots were colonized by Methanomicrobiales when grown on
river bank soil, in which RC-1 methanogens were initially not detectable. Roots
colonized with Methanomicrobiales compared with RC-1 exhibited lower CH4 production
and CH4 emission rates. The results show that the type of methanogens colonizing
rice roots has a potentially important impact on the global CH4 cycle.</abstract>
