Cactus pear biomass has the potential for bioethanol production in dry regions. However, its low solids concentration and pH variations may hinder the process of alcoholic fermentation. The objectives of this study were as follows: (1) to evaluate the effects of harvest time and season on biomass pH and dry matter concentration of cladodes of two cactus pear species commonly used as forage (Nopalea cochenillifera and Opuntia stricta); (2) to compare the hydrolysis of fresh and dried biomass (10…

Production and Application of Lignin-Based Chemicals and Materials in the Cellulosic Ethanol Production: An Overview on Lignin Closed-Loop Biorefinery Approaches
Lignocellulosic biomass is the most abundant biological resource on the planet and has been extensively researched to produce cellulosic ethanol. However, there is a consensus that the presence of

Towards Drylands Biorefineries: Valorisation of Forage Opuntia for the Production of Edible Coatings
Species of the genus Opuntia may be a well-suited feedstock for biorefineries located in drylands, where biomass is scarcer than in humid or temperate regions. This plant has numerous uses in Mexico
Effect of Different Sugar Beet Pulp Pretreatments on Biogas Production Efficiency
The analysis of energy balance showed that the increase in the number of SBP pretreatment operations significantly reduced the gain of electric energy.
Opuntia ficus-indica cladodes as feedstock for ethanol production by Kluyveromyces marxianus and Saccharomyces cerevisiae
K. marxianus has potential as an alternative to S. cerevisiae for bioethanol production, however, the relatively low concentration of fermentable sugars in the O. ficus-indica cladode hydrolysate presents a technical constraint for commercial exploitation.
Effect of three pretreatment techniques on the chemical composition and on the methane yields of Opuntia ficus-indica (prickly pear) biomass
Only the acidic pretreatment (HCl) was found to significantly increase methane generation and the methane yield of OFI biomass, and modelling of the cumulated methane production by the Gompertz modified equation was successful and aided in understanding kinetic advantages linked to some of the pretreatments.
Production of Ethanol by Three Yeasts in Defined Media and Hydrolyzed Cladodes of Opuntia ficus-indica var. Atlixco
Three yeast strains of Opuntia ficus indica cladodes were isolated, these strains were identified as Candida intermedia, Zygosaccharomyces bailii and Saccharomyces paradoxus. The yeasts were grown in
High annual productivity of certain agaves and cacti under cultivation
When irrigated and fertilized daily, Opuntia amyclea and O. ficus-indica in Saltillo, Coahuila, Mexico, had an average productivity of 46Mg ha−1 year−1, which are among the highest productivities ever reported for any plant species.
