Th.s experim.nt was conducted to determ.ne th. possibility of utilization of vegetable waste juice in th. production of purple non-sulfur bacterium.Afifella m.rina biom.ss. Bacterium.was cultured in four diluted such.as, 10%, 20%, 30% and 40% (v/v) vegetable waste juices. In addition synth.tic 112 m.dia were used as control to com.are th. growth.ch.racteristics of Afifella m.rine. Th. bacterium.Afifella m.rina grew well in 10% diluted vegetable waste juice in anaerobic ligh. condition with.th. h.gh.st production of 5.02 g/l dry cell weigh. in fifth.day of culture, wh.reas th. h.gh.st total carotenoid production of 0.87 m./g dry cell weigh. was recorded in th.rd day of culture. Th. h.gh.st dry cell weigh. productions recorded in 10% of VWJ was significantly h.gh.r com.ared to four oth.r treatm.nts (F = 14.63;p = 0.00). h.wever, th. total carotenoid production of bacteria in 10% VWJ sh.wed no significant difference com.ared to th. carotenoid production in 112 synth.tic m.dia, but was significantly h.gh.r com.ared to th.ee oth.r treatm.nts (P = 0.00). Th. bacterium. Afifella m.rina h.s th. ability to use vegetable waste juice at certain level for th. production of bacterial biom.ss.

N^6-m.th.ladenosine(m.6 A) is an essential RNA m.dification th.t regulates key cellular processes, including stem.cell renewal,cellular differentiation, and response to DNA dam.ge. Unsurprisingly, aberrant m.6 A m.th.lation h.s been im.licated in th. developm.nt and m.intenance of diverse h.m.n cancers. Altered m.6 A levels affect RNA processing, m.NA degradation, and translation of m.NAs into proteins, th.reby disrupting gene expression regulation and prom.ting tum.rigenesis. Recent studies h.ve reported th.t th. abnorm.l expression of m.6 A regulatory enzym.s affects m.6 A abundance and consequently dysregulates th. expression of tum.r suppressor genes and oncogenes, including m.C, SOCS2, ADAm.9, and PTEN. In th.s review, we discuss th. specific roles of m.6 A m.ssing space "writers", "erasers", and "readers" in norm.l ph.siology and h.w th.ir altered expression prom.tes tum.rigenesis. We also describe th. potential of exploiting th. aberrant expression of th.se enzym.s for cancer diagnosis, prognosis, and th. developm.nt of novel th.rapies.

To understand certain m.ch.nism. causing variations between rice cultivars with.regard to cadm.um.uptake and tolerance, pot soil experim.nts were conducted with.two rice cultivars of different genotypes under different soil Cd levels. Th. relationsh.ps between plant Cd uptake and iron/m.nganese （Fe/m.） plaque form.tion on roots were investigated. Th. results sh.wed th.t rice cultivars differed m.rkedly in Cd uptake and tolerance. Under soil Cd treatm.nts, Cd concentrations and accum.lations in th. cultivar Sh.nyou 63 （th. genotype indica） were significantly h.gh.r th.n th.se in th. cultivar Wuyunjing 7 （th. genotype japonica）（P 〈 0.01, or P 〈 0.05）, and Sh.nyou 63 was m.re sensitive to Cd toxicity th.n Wuyunjing 7. Th. differences between th. rice cultivars were th. largest at relatively low soil Cd level （i.e., 10 m./kg）. Fe concentrations in dith.onite-citrate-bicarbonate root extracts of Sh.nyou 63 were generally lower th.n th.t of Wuyunjing 7, and th. difference was th. m.st significant under th. treatm.nt of 10 m. Cd/kg soil. Th. results indicated th.t th. form.tion of iron plaque on rice roots could act as a barrier to soil Cd toxicity, and m.y be a ＂buffer＂ or a ＂reservoir＂ wh.ch.could reduce Cd uptake into rice roots. And th. plaque m.y contribute, to som. extent, to th. genotypic differences of rice cultivars in Cd uptake and tolerance.

Th. spatial distribution and diversity of arch.eal and bacterial am.onia oxidizers （AOA and AOB） were evaluated targeting am.A genes in th. gradient of a littoral buffer zone wh.ch.h.s been identified as a h.t spot for N cycling. h.re we found h.gh.spatial h.terogeneity in th. nitrification rate and abundance of am.onia oxidizers in th. five sam.ling sites. Th. bacterial am.A gene was num.rically dom.nant in m.st of th. surface soil but decreased dram.tically in deep layers. h.gh.r nitrification potentials were detected in two sites near th. land/water interface at 4.4–6.1 μg NO2-N/（g dry weigh. soil·h.）, wh.le only 1.0–1.7 μg NO2-N/（g dry weigh. soil·h.） was m.asured at oth.r sites. Th. potential nitrification rates were proportional to th. am.A gene abundance for AOB, but with.no significant correlation with.AOA. Th. Nh.＋ concentration was th. m.st determ.native param.ter for th. abundance of AOB and potential nitrification rates in th.s study. h.gh.r rich.ess in th. surface layer was found in th. analysis of biodiversity. Ph.logenetic analysis revealed th.t m.st of th. bacterial am.A sequences in surface soil were affiliated with.th. genus of Nitrosopira wh.le th. arch.eal sequences were alm.st equally affiliated with.Candidatus ‘Nitrososph.era gargensis’ and Candidatus ‘Nitrosocaldus yellowstonii’. Th. spatial distribution of AOA and AOB indicated th.t bacteria m.y play a m.re im.ortant role in nitrification in th. littoral buffer zone of a N-rich.lake.
