“…For the herbaceous lignocellulose, we selected a dwarf type of napiergrass (Pennisetum purpureum Schumach), which is a digestible tropical grass [16,17]. Napiergrass was cultivated in the Kibana Agricultural Science Station, at the University of Miyazaki.…”

“…We were interested in ethanol production from herbaceous lignocellulosic napiergrass (Pennisetum purpureum Schumach) because of its low lignin content and high harvest amount per year and per area [16,17]. Ethanol was produced from non-pretreated napiergrass through simultaneous saccharification and fermentation (SSF) as well as pentose fermentation (PF) with recombinant Escherichia coli KO11 [18].…”

Napiegrass (Pennisetum purpureum Schumach) was treated with a low-moisture anhydrous ammonia (LMAA) pretreatment by adding an equal weight of water and keeping it under atmospheric ammonia gas at room temperature for four weeks. After the removal of ammonia and washing with water, a simultaneous saccharification and fermentation (SSF) was conducted for the LMAA-pretreated napiergrass (1.33 g) in a buffer solution (8 mL) using a mixture of a cellulase (80 mg) and a xylanase (53 mg) as well as the cell suspension (0.16 mL) of Saccharomyces cerevisiae. Ethanol and xylose resulted in 91.2% and 62.9% yields, respectively. The SSF process was scaled up using LMAA-pretreated napiergrass (100.0 g) to give ethanol (77.2%) and xylose (52.8%). After the removal of ethanol, the pentose fermentation of the SSF solution (40 mL), which contained 1.00 g of xylose, using cell suspension of Escherichia coli KO11 (70 mL) gave 86.3% yield of ethanol. Total ethanol yield reached 68.9% based on xylan (21.4 wt%) and glucan (39.7 wt%) of the LMAA-pretreated napiergrass.

“…Application of DEM to soil surface was proved to improve soil chemical properties without major contamination to the environments of arable lands (Hasyim et al, 2014). Several studies in Thailand (Rengsirikul et al, 2011) and Florida, USA (Woodard and Prine, 1993) noted that the recommended application rate at 20-30 g N m −2 are crucial to sustain high yield and quality in napiergrass.…”

“…Napiergrass (Pennisetum purpureum Schumach) is a C 4 tropical grass which produces abundantly nutritious green forage and is considered to be excellent feeds for livestock under both green-chopping and grazing systems in the tropics (Vicente-Chandler et al, 1959;Woodard and Prine, 1993) as well as in temperate Kyushu, Japan (Sunusi et al, 1999;Wadi et al, 2004;Idota et al, 2005;Hasyim et al, 2010), affected by the various conditions such as growth stages, climatic factors and defoliation intensity (Zewdu et al, 2002). Several genotypes of napiergrass were investigated for the potential biofuel production in the tropics (Williams and Hanna, 1995;Rengsirikul et al, 2011) and in temperate Kyushu (Khairani et al, 2013). Napiergrass required heavy fertilization and careful management to maintain a rapid growth with quality forage under the subtropical climate in Australia (Jones, 1985) as well as in southern Kyushu, Japan (Sunusi et al, 1999;Wadi et al, 2003).…”

Digested effluent produced by a biogas-plant contains essential plant nutrients to solve the treated and disposal problems of livestock manure. Dwarf variety of late-heading type (dwarf) napiergrass as a perennial summer crop and intercropping of over-sown Italian ryegrass as an annual winter crop were applied to 3 levels of digested effluent in southern Kyushu from 2007 to 2009. Digested effluent revealed so effective fertilizer as chemical one to increase dry matter yield, wintering ability and forage quality in crude protein concentration and in vitro dry matter digestibility (digestibility) with increasing application rate. Digestibility in leaf blade of napiergrass and that in whole Italian ryegrass were positively correlated with acid detergent lignin and neutral detergent fiber concentrations, respectively, which might be mediated with reducing tiller size with defoliation proceeded. The present cropping systems have a potential under sufficient application of the effluent to achieve sustainable quality herbage production in southern Kyushu, Japan.

“…The evaluations were carried out in two periods (cuts), the first cut made after 12 months of sowing (2014), and the second cut 8 months after the first (2015). According to Rengsirikul et al (2011), biomass yield, growth components, and chemical composition decreased after a 12-month interval of dry matter in elephant grass.…”

ABSTRACT. Genetically improved cultivars of elephant grass need to be adapted to different ecosystems with a faster growth speed and lower seasonality of biomass production over the year. This study aimed to use selection indices using mixed models (REML/BLUP) for selecting families and progenies within full-sib families of elephant grass (Pennisetum purpureum) for biomass production. One hundred and twenty full-sib progenies were assessed from 2014 to 2015 in a randomized block design with three replications. During this period, the traits dry matter production, the number of tillers, plant height, stem diameter, and neutral detergent fiber were assessed. Families 3 and 1 were the best classified, being the most indicated for selection effect. Progenies 40, 45, 46, and 49 got the first positions in the three indices assessed in the first cut. The gain for individual 40 was 161.76% using Mulamba and Mock index. The use of selection indices using mixed models is advantageous in elephant grass since they provide high gains with the selection, which are distributed among all the assessed traits in the most appropriate situation to breeding programs.
