Brazilian fruit processing, wastes as a source of lipase and other biotechnological products: a review Anais da ABC (AABC)
OKINO-DELGADO,CLARISSA H.; PRADO,DÉBORA Z.; FLEURI,LUCIANA F..
Abstract The global food loss and waste is the most urgent research area in food science to attend the current demand for more sustainable and profitable processes. Along the productive chain about 1/3 of the food is lost or wasted, this number reaches 1/2 for fruit and vegetable production in developing countries. Brazil has been investing in researches aiming to turn its wastes into byproducts, as biomolecules of high value such as lipases. These enzymes are found in a high diversity of plant sources and their researches are covered by promising market growth expectations due to the current demand for biofuels and bio-transformed food. Thus, the aim of the present study is to discuss the potential of wastes generated by the Brazilian fruit processing to...

Characterization of biomasses from the north and northeast regions of Brazil for processes in biorefineries Ciênc. Tecnol. Aliment.
RAMBO,Magale Karine Diel; ALEXANDRE,Gerso Pereira; RAMBO,Michele Cristiane Diel; ALVES,Aparecido Roberto; GARCIA,Wokimar T.; BARUQUE,Edmond.
Abstract In search for renewable energy sources, the Brazilian residual biomasses stand out due to their favorable physical and chemical properties, low cost, and their being less pollutant. Therefore, they are likely to be used in biorefineries in the production of chemical inputs to substitute fossil fuels. This substitution is possible due to the high contents of carbohydrates (>40%), low contents of extractives (<20%), ashes (<8%) and moisture (<8%) found in these residual biomasses. High calorific values of all residues also offer them the chance to be used in combustion. A principal components analysis (PCA) was performed for better understanding of the samples and their hysic-chemical properties. Thus, this study aimed to characterize...

Cost Analysis of Alternative Harvest, Storage and Transportation Methods for Delivering Switchgrass to a Biorefinery from the Farmers’ perspective AgEcon
Wang, Chenguang; Larson, James A.; English, Burton C.; Jensen, Kimberly L..
Switchgrass for bioenergy production will require substantial storage. This study evaluated costs of alternative baling and on-farm storage systems. Rectangular bales minimize cost if switchgrass is processed immediately after harvest. However, round bales minimize cost if switchgrass is stored under cover for 200 days before transporting to the biorefinery
Tipo: Conference Paper or Presentation Palavras-chave: Switchgrass; Baling; Storage; Transport; Costs; Farm; Biorefinery; Agribusiness; Agricultural Finance; Environmental Economics and Policy; Farm Management; Production Economics; Resource /Energy Economics and Policy.

Enzyme-assisted extraction (EAE) for the production of antiviral and antioxidant extracts from the green seaweed Ulva armoricana (Ulvales, Ulvophyceae) ArchiMer
Hardouin, Kevin; Bedoux, Gilles; Burlot, Anne-sophie; Donnay-moreno, Claire; Berge, Jean-pascal; Nyvall-collen, Pi; Bourgougnon, Nathalie.
In order to develop innovative methods for the production of bioactive extracts with potential health benefits, enzyme-assisted extraction has been applied for the bioconversion of Ulva armoricana (Ulvales, Ulvophyceae). The extraction yields, chemical composition, the antioxidant and antiviral activities were determined to assess the efficiency of six commercial enzymatic preparations. Endo-protease treatments significantly increased the extraction yields compared to the control. The organic matter, neutral sugar and protein contents were increased in all extracts compared to an extraction with water, up to 2.0-fold, 2.7-fold and 1.75-fold, respectively. The samples prepared by a multiple-mix of glycosyl-hydrolases and an exo-β-1,3(4)-glucanase revealed...

Production, purification and characterization of an ionic liquid tolerant cellulase from Bacillus sp. isolated from rice paddy field soil Electron. J. Biotechnol.
Sriariyanun,Malinee; Tantayotai,Prapakorn; Yasurin,Patchanee; Pornwongthong,Peerapong; Cheenkachorn,Kraipat.
Background: Lignocellulosic biomass is a renewable, abundant, and inexpensive resource for biorefining process to produce biofuel and valuable chemicals. To make the process become feasible, it requires the use of both efficient pretreatment and hydrolysis enzymes to generate fermentable sugars. Ionic liquid (IL) pretreatment has been demonstrated to be a promising method to enhance the saccharification of biomass by cellulase enzyme; however, the remaining IL in the hydrolysis buffer strongly inhibits the function of cellulase. This study aimed to isolate a potential IL-tolerant cellulase producing bacterium to be applied in biorefining process. Result: One Bacillus sp., MSL2 strain, obtained from rice paddy field soil was isolated based on screening of...

Switchgrass to Ethanol: A Field to Fuel Approach AgEcon
Haque, Mohua; Epplin, Francis M..
The U.S. Energy Independence and Security Act of 2007 mandates the production of 16 billion gallons of cellulosic biofuels by 2022. Desirable feedstock properties, biomass to biofuel conversion rate, and investment required in plant and equipment differs depending on which of several competing technologies is used. The objective is to determine the breakeven ethanol price for a cellulosic biorefinery. A comprehensive mathematical programming model that encompasses the chain from land acquisition to ethanol production was constructed and solved. For a capital requirement of $400 million for a 100 million gallons per year plant and a conversion rate of 100 gallons of ethanol per dry ton, the breakeven ethanol price is $1.91 per gallon: $0.20 for land rental...
