The present work consists of producing bioethanol from potato (Solanum tuberosum L.) peels using Saccharomyces cerevisiae. different physicochemical and biochemical analyses showed that are rich in nutritional elements make them favorable to alcohol fermentation. total soluble sugars content, the pH value ethanol content were evaluated. results indicated limited production. addition yeast extra...

Chemical properties of cationic biosorbents, the orange peel and the lemon peel, have been studied. ATR and Raman spectra indicated that the functional groups in the peels structure responsible for dye sorption are carboxyl groups (COOH and COOM, M=Na,K,Ca,Mg) and hydroxyl groups (OH). Increasing the mass of the peels in water suspensions a decrease in dissociation of both, the –COOH and –COOM ...

12 female and 12 castrate male sheep were allocated to ration. containing dried fermented cassava peels at 0,20, 40 and 60% over a 6 month period to determine the optimum level at which maize could be replaced without any effect on digestibility of rations and liveweight performance. Carcass-and economic characteristics were determined. 40 and 60% fermented cassava peels significantly depressed...

Dried and ground peel biomass, ripe waste banana and Hydrolyzed peels of green and red banana used for bio ethanol production by Saccharomyces cerevisiae with shake flask culture. The substrate was given with different concentration as 1%, 2.5%, 5%, 7.5% and 10% (w/v) along with 1% inoculum. Saccharomyces cerevisiae exhibited maximum yield of ethanol in ripened red banana and their hydrolyzed p...

In the Pre-Elementary Education Longitudinal Study (PEELS), imputation of item missing data was done using AutoImpute (AI) software, which uses semi-parametric modeling to form imputation classes. In this paper, we summarize PEELS experience with AI, investigate the bias aspect of the imputed data for the PEELS teacher questionnaire data, and study the variance estimation of imputed data using ...

The presence of chloroplasts in guard cells from leaf epidermis, coleoptile, flowers, and albino portions of variegated leaves was established by incident fluorescence microscopy, thus confirming the notion that guard cell chloroplasts are remarkably conserved. Room temperature emission spectra from a few chloroplasts in a single guard cell of Vicia faba showed one major peak at around 683 nano...

Nowadays, there is a requirement for industries to eliminate carbon from their energy mix and substitute it with greener options. This calls investment in efforts facilitate the scaling up of technical advancements. Because huge amount waste, life cycle strategy has been used by industries, especially food industry, lessen environmental impact products. One sectors that burdens environment sign...

As an agroindustrial waste product, potato peels contain valuable phenolic compounds that can be extracted before they are sent to the landfill. Based on previous work, this study focused determining efficacies of compound extraction from using conventional shaking (CSE) and both direct ultrasound-assisted (DUAE), indirect (IUAE). The yield curve associated with each method was measured charact...

Sweet potato is grown extensively from tropical to temperate regions and is an important food crop worldwide. In this study, we established detection methods for 17 major sweet potato viruses using single and multiplex RT-PCR assays. To investigate the current incidence of viral diseases, we collected 154 samples of various sweet potato cultivars showing virus-like symptoms from 40 fields in 10...
