This research aims to select the optimum pretreatment conditions to increase fermentable sugar production during enzymatic hydrolysis for bioethanol production. Initially, sulfuric acid at a concentration of 0.5, 1.0, 1.5, and 2.0% (v/v) pre-treated barley straw biomass was applied by autoclaving at 121℃ for 15 lb/in2 pressure for 15 min. Furthermore, acid-treated barley straw under the alkaline condition with calcium hydroxide concentrations of 1, 2, 3, and 4% (w/v) was autoclaved at 121℃ for 15 lb/in2 pressure for 15 min. Subsequently, the pretreatment of barley straw in the acetic and alkaline processes was compared. It was found that calcium hydroxide at a concentration of 2% (w/v) gave more sugar concentrations. Finally, combined acid and alkaline pretreatment with 2% of cellulase enzymatic hydrolysis had the highest total sugar concentration of 205.43 g/L and reducing sugar of 134.42 g/L, producing the highest ethanol yield (16.17 g/L) by 24 hours of fermentation.","PeriodicalId":18176,"journal":{"name":"Maejo International Journal of Energy and Environmental Communication","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82848009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Global wide has a variety of environmental impacts due to its use of fossil fuels. Bioethanol might be produced in Asian locations from many types of biomasses, including agricultural waste, forest waste, and wood biomass. This would be an environmentally friendly process. Unfortunately, there is very little research into the production of ethanol from rice field weeds. This makes it difficult to develop bioethanol production.

The cost of extending the national grid or installing off-grid systems is determined by a variety of factors, including the area's location, geography, population, distance from a grid point, and land size. Due to their cost-effectiveness and ease, off-grid rural electrification systems that incorporate a variety of renewable energy sources (RESs) have become unavoidable in areas where grid connectivity is neither available nor feasible. A hybrid combination of renewable energy technologies (RETs) has demonstrated to be a viable alternative to costly grid extension in remote areas throughout the world. The purpose of this study was to plan and assess the techno-economic feasibility of providing electricity to rural Enttelat in Libya using renewable energy sources, considering 70 houses with a combined load of 875 kWh/d. Three significant outcomes were obtained because of the techno-economic design using the HOMMER tool. These three primary outcomes were chosen for their resource availability and cost-effectiveness. When several input parameters such as annual average load, scaled annual average solar resource, wind speed, annual real interest rate, and solar PV and wind component prices were varied, the sensitivity analysis revealed that hybrid system solar PV-wind renewable resource has a high potential, especially if the location is remote from a grid source.","PeriodicalId":18176,"journal":{"name":"Maejo International Journal of Energy and Environmental Communication","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85209299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is renewable, low-cost, and the preferred fuel for most developing countries worldwide. Although it is possible to make bioethanol from corn stalks and leaves wastes, second-generation biofuels made from agricultural waste feedstocks represent a significant step forward. In the present research, nickel oxide (NiO) nanoparticles (NPs) were used as a biocatalyst to achieve maximum ethanol output. The pretreatment of 2% NaOH with NiO NPs, 15-min autoclave condition, showed the highest total and reducing sugar yield was 162.69 g/L and 43.75 g/L. After hydrolysis, the suitable total and reducing sugar yield of 185.43 g/L and 125.42 g/L was chosen for further fermentation with the expansion of Saccharomyces cerevisiae cells. Separate hydrolysis and fermentation (SHF) using corn stalk and leaf waste was significantly assisted by incorporating a nanocatalyst; ethanol concentration was increased to 15.8 g/L at 24 hours incubation period. The study revealed critical information regarding ways NiO NPs could be employed to improve the efficiency of the ethanol production bioprocess.","PeriodicalId":18176,"journal":{"name":"Maejo International Journal of Energy and Environmental Communication","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85396910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This medicinal plant mainly grows in Kashmir, Himachal Pradesh, and North-west Himalayas. The medicinal plant's root and rhizome are frequently used by native people for various local remedies. This species has become critically endangered due to its endemic nature and high rate of extraction from its natural environment. In India rhizome and root of this medicinal plant are used as ant periodic, bitter tonics, anti-inflammatory, blood purifier, expectorant, antipsychotic, carminative, and stomachic. Genitiana kurroo can be propagated through micro-filtration of seeds, rhizome cutting, shoot-made segments, and somatic embryogenesis. The roots of Genitiana kurroo are rich in various ingredients such as flavonoids, alkaloids, and terpenoids which are responsible for analgesic, anticancer, and immune-modular effects. Considering these perspectives the present review has intended to provide updated prospects of Gentiana kurroo and provides insights on the nutritional and various pharmacological properties based on updated research literature.

Presently, a response surface method (RSM), has been utilized to characterize the influence of the affecting parameters and a global sensitivity analysis has been conducted to put forward the critical parameters that influence the performance of the device. It is observed that an increase in frequency for lower pressure ratios with higher mean pressure results in better cooling performance in smaller pulse tube diameter models.
