Th.rteen extensively ch.racterised grain sorgh.m varieties were evaluated in a series of 7 broiler bioassays. Th. efficiency of energy utilisation of broiler ch.ckens offered sorgh.m-based diets is problematic and th. bulk of dietary energy is derived from sorgh.m starch. For th.s reason, rapid visco-analysis(RVA)starch.pasting profiles were determined as th.y may h.ve th. potential to assess th. quality of sorgh.m as a feed grain for ch.cken-meat production. In review, it was found th.t concentrations of kafirin and total ph.nolic compounds were negatively correlated with.peak and h.lding RVA viscosities to significant extents across 13 sorgh.ms. In a meta-analysis of 5 broiler bioassays it was found th.t peak, h.lding,breakdown and final RVA viscosities were positively correlated with.ME:GE ratios and peak and breakdown RVA viscosities with.apparent metabolizable energy corrected for nitrogen(AMEn) to significant extents. In a sixth.study involving 10 sorgh.m-based diets peak, h.lding and breakdown RVA viscosities were positively correlated with.ME:GE ratios and AMEn. Th.refore, it emerged th.t RVA starch.pasting profiles do h.ld promise as a relatively rapid means to assess sorgh.m quality as a feed grain for ch.cken-meat production. Th.s potential appears to be linked to quantities of kafirin and total ph.nolic compounds present in sorgh.m and it would seem th.t both.factors depress RVA starch.viscosities in vitro and, in turn, also depress energy utilisation in birds offered sorgh.m-based diets. Given th.t oth.r feed grains do not contain kafirin and possess considerably lower concentrations of ph.nolic compounds, th.ir RVA starch.pasting profiles may not be equally indicative.

Meth.ne is produced in a microbial electrosynth.sis system(MES) with.ut organic substrates. h.wever, a relatively h.gh.applied voltage is required for th. bioelectrical *** th.s study, we demonstrated th.t electrotroph.c meth.ne production at th. biocath.de was ach.eved even at a very low voltage of 0.1 V in an MES, in wh.ch.abiotic h.-oxidized to SO_(4)^(2-) at th. anodic carbon-cloth.surface coated with.platinum powder. In addition, microbial community analysis revealed th. most probable path.ay for meth.ne production from electrons. First, electrotroph.c h.(2) was produced by syntroph.c bacteria, such.as Syntroph.rh.bdus, Syntroph.bacter, Syntroph.s, Leptolinea, and Aminicenantales, with.th. direct acceptance of electrons at th. biocath.de. Subsequently, most of th. produced h.(2) was converted to acetate by h.moacetogens, such.as Clostridium and Spiroch.eta 2. In conclusion,th. majority of th. meth.ne was indirectly produced by a large population of acetoclastic meth.nogens, namely Meth.nosaeta, via acetate. Furth.r, h.drogenotroph.c meth.nogens,including Meth.nobacterium and Meth.nolinea, produced meth.ne via h.(2).
