Compared to traditional lignocellulose biomass, microalgae contain little or no lignin. Traditionally, bioethanol production from undergoes three major steps: (i) pretreatment; (ii) polysaccharides hydrolysis into simple sugars; and (iii) sugar conversion by fermentation. Microalgae convert sunlight, water, CO2 algal biomass. Diatoms, green algae, bluegreen golden algae are four main classes of...

development in the production of agricultural products can take place in two ways: 1) increasing the inputs, which due to limitations in resources is possible only up to a specified level. the second possibility is to increase the productivity of the units by making use of new technologies. technology is defined as, substituting new ways of production for the old ones to increase production per...

energy is considered as an important input for agricultural products. a decrease in energy subsidy and its demand reduces agricultural outputs and raises the production costs. changes in production and costs may significantly affect welfare of the agricultural producers. the main objective of this study was to analyze the impact of increased energy prices (reduction in the subsidy) on the agric...
