Bac.gro.nd： Two.appro.c.es mark the differenc. between the ＂ec.0}o.ic.l＂ and ＂agric.ltural＂ view o. the bio.iversity/ gro.th relatio.. In ec.0}o.y the trend is averaged by taking mo.o.ultures o. all spec.es as baseline to.evaluate mixtures. This c.0}trasts the ＂agric.ltural＂ view fo.using o. the mo.t pro.uc.ive spec.es o. spec.es c.0}binatio. as baseline to.evaluate mixtures. The present study investigates the c.ange o. highest rates （maximum） pro.uc.ivities in grasslands and fo.ests with inc.easing plant （o. tree） diversity, and c.0}pares these with the average respo.se. Metho.s： We base o.r analysis o. existing published datasets relating the gro.th o. plant stands （gro.th rate per land area） to.the diversity o. the same plo.. We use a glo.al dataset （ellis et al. 2012 and Mo.IS-data, see Fig. 1）, the grassland experiment in lena （Buc.mann et al. 2017）, the regio.al study o. fo.ests in Ro.ania and Germany by Bo.riaud et al. （2016）, and data fro. the German Natio.al Fo.est invento.y （BWl 3, see Fig. 3）. In all c.ses the average respo.se o. gro.th to.c.anges in bio.iversity as well as the bo.ndary line o. the maximum values was c.lc.lated. Results： in bo.h vegetatio. types a dec.easing trend o. maximum pro.uc.ivity with any added spec.es emerges, c.0}trasting the average trend that was po.itive in grassland, but absent in fo.ests. The trend o. maximum values was no.-signific.nt in grasslands pro.ably due to.the fac. that no. all c.0}binatio.s o. spec.es mixtures were available. In temperate fo.ests, maximum pro.uc.ivity dec.eases signific.ntly by abo.t 10% in regio.al studies and by 8% at natio.al sc.le with eac. added spec.es. Maximum bio.ass per area was the same fo. managed and unmanaged c.0}ditio.s. A glo.al assessment o.

The suc.essful o.eratio. o. any type o. hydro.en-pro.uc.ng bio.eac.o. depends o. the perfo.manc. o. the mic.o.rganisms present in the system. Bo.h substrate and partial gas pressures are c.uc.al fac.o.s affec.ing dark fermentatio. metabo.ic.pathways. The main o.jec.ive o. this study was to.evaluate the impac. o. bo.h fac.o.s o. hydro.en pro.uc.io. using anaero.ic.granular sludge as ino.ulum and, sec.0}dly, to.study the metabo.ic.shifts o. an anaero.ic.c.0}munity subjec.ed to.lo. partial gas pressures. With this go.l in mind, seven different wastewater （fo.r synthetic.media, two.industrial waste- water, and o.e do.estic.effluent） and the effec. o. applying vac.um o. the systems were analyzed. The applic.tio. o. vac.um pro.o.ed an inc.ease in the diversity o. hydro.en-pro.uc.ng bac.eria, suc. as c.o.tridium, and pro.o.ed the do.inanc. o. ac.to.lastic.0}er hydro.eno.ro.hic.methano.ens.

Nevertheless, reduc.io. o. the hydro.en partial pressure by applic.tio. o. vac.um lead to.further o.idatio. o. reac.io. intermediates irrespec.ive o. the medium used, whic. resulted in higher hydro.en and methane pro.uc.io., and impro.ed the c.0} remo.al. Interestingly, vac.um greatly pro.o.ed bio.enic.hydro.en pro.uc.io. fro. a real wastewater, whic. o.ens po.sibilities fo. future applic.tio. o. dark fermentatio. systems to.enhanc. bio.ydro.en yields.

Impact of traditional treatments on the nutritional value of Artocarpus heterophyllus seeds was evaluated. Four traditional processing methods were used (boiling, roasting, soaking and fermentation). Boiled A. heterophyllus (BAH) samples were boiled in water for 60 minutes, roasted A. heterophyllus (RAH) samples were roasted in fine sand, soaked A. heterophyllus (SAH) were soaked in clean water for 48 hours before boiling while the fermented A. heterophyllus (FAH) samples were boiled and wrapped in black bag for 48 hours. The mean proximate content (%) of the unprocessed A. heterophyllus (UAH) seeds was;protein (15.88 ± 0.08), fibre (10.04 ± 0.09) ash (5.05 ± 0.07), moisture (29.25 ± 0.35), fat (10.26 ± 0.35) and carbohydrate (29.52 ± 0.4).
