Última Stochastic Viability of Second Generation Biofuel Chains: Micro-economic Spatial Modeling in France AgEcon Bamiére, Laure; Martinet, Vincent; Gouel, Christophe; Le Cadre, Elodie. Within an overall project to assess the ability of the agricultural sector to contribute to bioenergy production, we set out here to examine the economic and technological viability of a bioenergy facility in an uncertain economic context, using the stochastic viability approach. We consider two viability constraints: the facility demand for lignocellulosic feedstock has to be satisfied each year and the associated supply cost has to be lower than de profitability threshold of the facility. We assess the viability probability of various supplying strategies consisting in contracting a given share of the feedstock demand with perennial dedicated crops at the initial time and then in making up each year with annual dedicated crops or wood. The demand...

Ano: 2011 URL: http://purl.umn.edu/114238 Biomass for energy production in the context of selected European and international policy objectives AgEcon Becker, Arno. Biomass based energy production has attained a significant market share within the developing renewable energy market. In comparison to alternative renewable energy sources, biomass has several special features: it is not inexhaustible in the short term (limitation of arable land) and it is not only an energy source. Other usages like food or feed compete with energy production for this resource. A number of problems arise which have a direct impact on the fulfillment of policy objectives which are connected with its promotion. Primarily, the production of bioenergy has significant impacts on coupled biomass markets. Further, a change in production intensity or arable land use increases the use of nutrient loads and agro - chemicals. When evaluating...

Ano: 2008 URL: http://purl.umn.edu/43974 Can Dispersed Biomass Processing Protect the Environment and Cover the Bottom Line for Biofuel? AgEcon Egbendewe-Mondzozo, Aklesso; Swinton, Scott M.; Bals, Bryan D.; Dale, Bruce E.. This paper compares environmental and profitability outcomes for a centralized biorefinery for cellulosic ethanol that does all processing versus a biorefinery linked to a decentralized array of local depots that pretreat biomass into concentrated briquettes. The analysis uses a spatial bioeconomic model that maximizes predicted profit from crop and energy products, subject to the requirement that the biorefinery must be operated at full capacity. The model draws upon biophysical crop input-output coefficients simulated with the EPIC model, as well as input and output prices, spatial transportation costs, ethanol yields from biomass, and biorefinery capital and operational costs. The model was applied to 82 cropping systems simulated across 37...

Pegoraro,Rodinei Facco; Souza,Bruna Aparecida Madureira de; Maia,Victor Martins; Amaral,Uirá do; Pereira,Marlon Cristian Toledo. This study aimed to evaluate the growth characteristics of irrigated Vitória pineapple plants grown in semi-arid conditions and determine its developmental stages based on those characteristics. It was used a randomized block design with four replicates. The experimental treatments were: plant harvest at 270, 330, 390, 450, 510, 570, 690, 750, and 810 days after planting (DAP). The following variables were determined: plant height, stem diameter, D-leaf length, D-leaf fresh and dry mass, biomass production of plants and plant parts (organs), and vegetative biomass. Five phenological stages are proposed based on vegetative biomass production: < 20% biomass production (V1); 21-40% (V2); 41-60% (V3); 61-80% (V4); and &gt; 80% (V5). The maximum growth...

The effects of water availability were evaluated on the photosynthetic tissue anatomy in Aloe vera(L) Burm f. and its relationship with morphological, physiological parameters, and water use efficiency as a function of aerial biomass and gel production. Plants were subjected to four levels of water availability equivalent to 20% (T1), 15% (T2), 10% (T3), and 5% (T4) of the atmospheric evaporative demand. The plants exhibited anatomical, morphological, and physiological responses to the different watering treatments. The extreme treatments produced negative responses due to excess water in T1 and water deficit in T4. Treatments T2 and T3 elicited positive responses in cell characteristics and productivity. Anatomical and structural characteristics were... Tipo: Journal article Palavras-chave: Anatomical adaptations; Biomass production; Growth; Stomata.

Calcium ions (Ca) play an important role in many biochemical processes, delaying senescence and controlling physiological disorders in fruits and vegetables. The objective of this experiment was to analyze the effect of increasing calcium concentrations in snap beans. Snap bean cultivar UEL 1 was sown in sand containing 80 mg L-1 of calcium supplemented with nutrient solution, plus calcium at different contents: 0, 75, 150 and 300 mg L-1. Ca was mainly recovered in the shoots, followed by roots and pods. Calcium concentrations in the pods were 130, 259, 349 and 515 mg 100 g-1dry matter on a dry weight basis, in relation to the enhancement of calcium contents in the nutrient solution, respectively. A negative relationship between nitrogen content in the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Phaseolus vulgaris L.; Biomass production; Pod; Nutrient solution; Nitrogen.

Jesús; Gómez-Guerrero,Armando. Biomass production is an important criterion to be considered for the establishment of commercial forestry plantations for bioenergy production. In this study, an estimation of net aerial primary production (NAPP) was made in a young plantation of Bambusa oldhamii Munro from the sum of biomass production from growth of new culms, biomass increment of the pre-existing culms, and production of litter. Biomass production in the incorporated culms was 15.82 Mg ha-1 year-1, of which 13.77 Mg (87 %) corresponded to stems and 2.05 Mg (13 %) to foliage. Biomass increment in the pre-existing culms was 10.88 Mg ha-1. One- and two-year-old cohort production was 7.31 and 3.57 Mg ha-1. Litter production was 5.56 Mg ha-1 year-1. Results show that NAPP was 32.20 Mg ha-1,... Tipo: Info:eu-repo/semantics/article Palavras-chave: Bamboo; Litter; Biomass production; Bioenergy; Tropical forest species.

Boletín de Investigaciones García-Ulloa Gómez,Manuel; Gamboa Delgado,Julián; Zavala Aguirre,José Luis; Ogura Fujii,Tetsuya; Lavens,Patrick. Total length and biomass production of the brine shrimp Artemia franciscana were studied fed on soybean and wheat micropulverized meals (applied alone or mixed at different proportions), live microalgae (Tetraselmis suecica and Chaetoceros calcitrans), and dried Spirulina as diets. Eight diets were tested in triplicates during 10 days. Significant differences (P < 0.05) were observed from day 1 onwards. The mixed meal-based diets showed better production results. At day 1, the Artemia nauplii fed on the 70% wheat meal/ 30% soya meal diet were 30% longer compared to the animals from the C. calcitrans group. At day 10, the organisms fed with the 100% soya meal diet were 68% longer than those fed on the C. calcitrans diet. The final biomass production (wet...

Ano: 1999 URL: http://www.scielo.org.co/scielo.php?script=sci_arttext&pid=S0122-97611999000100001 Effect of three different types of culture conditions on Spirulina maxima growth BABT Monteiro,Maria Paula da Costa; Luchese,Rosa Helena; Absher,Theresinha Monteiro. Growth of Spirulina maxima was studied in three types of culture conditions with four replicates each: 1) manual aeration with natural sunlight; 2) manual aeration with artificial light; and 3) constant aeration with an aquarium compressor and artificial light. After 185 days of incubation, growth declined in the first two treatments, while in the third treatment, higher growth was observed with average optical density of 3.7 against 1.8 and 1.9 in the first and second treatment, respectively. This was probably due to the fact that under constant aeration the salts were suspended avoiding the crystallization what could cause a decrease in the availability of the necessary nutrients for the growth. Also, the constant stirring allowed all the cells to... Tipo: Info:eu-repo/semantics/article Palavras-chave: Aquarium compressor; Biomass production; Microalgal growth; Spirulina.

The effect of soil polluted by diesel oil on the germination of seeds and the growth of Schinus terebinthifolius Raddi seedlings was analyzed at different times after contamination of the soil. The experiments were conducted under greenhouse conditions, with four treatments and five repetitions. The four treatments included: soil contaminated 30 (T30), 90 (T90) or 180 (T180) days before planting as well as a non-polluted soil (T0) (control). Soil saturated to 50% of its maximum retention capacity (MRC) was contaminated with diesel oil at a rate of 92.4 mL per kg. The germination rate and germination speed index (GSI) were significantly affected only in T30. The development of the plants was affected significantly in all the treatments, with reductions of...

Response surface methodology (RSM) was employed to study the effects of various medium components on biomass production by Lactobacillus rhamnosus E/N. This strain is commonly used in the pharmaceutical and food industries due to its beneficial effect on the human gut and general health. The best medium composition derived from RSM regression was (in g/l) glucose 15.44, sodium pyruvate 3.92, meat extract 8.0, potassium phosphate 1.88, sodium acetate 4.7, and ammonium citrate 1.88. With this medium composition biomass production was 23 g/l of dry cell weight after 18 h of cultivation in bioreactor conditions, whereas on MRS the yield of biomass was 21 g/l of dry cell weight. The cost of 1 g of biomass obtained on MRS broth was calculated at the level of...
