“…A previous saccharification study from oil palm trunk (OPT) demonstrated that Epsom salt (MgSO 4 ) and alanine amino acid (C 3 H 5 NO 2 ) addition, during hydrolysis increased the sugar yield from 12.52% to 17.19% [27]. Hence, additional supplements, such as vitamin B 12 , Epsom salt, alanine amino acid, and other vitamins-minerals, as well as recombinant yeast and yeast strains to the fermentation solution, are highly recommended for further experiments to obtain desired sugar content [43].…”

Banana stem is being considered as the second largest waste biomass in Malaysia. Therefore, the environmental challenge of managing this huge amount of biomass as well as converting the feedstock into value-added products has spurred the demand for diversified applications to be implemented as a realistic approach. In this study, banana stem waste was experimented for bioethanol generation via hydrolysis and fermentation methods with the presence of Saccharomyces cerevisiae (yeast) subsequently. Along with the experimental analysis, a realistic pilot scale application of electricity generation from the bioethanol has been designed by HOMER software to demonstrate techno-economic and environmental impact. During sulfuric acid and enzymatic hydrolysis, the highest glucose yield was 5.614 and 40.61 g/L, respectively. During fermentation, the maximum and minimum glucose yield was 62.23 g/L at 12 h and 0.69 g/L at 72 h, respectively. Subsequently, 99.8% pure bioethanol was recovered by a distillation process. Plant modeling simulated operating costs 65,980 US$/y, net production cost 869347 US$ and electricity cost 0.392 US$/kWh. The CO 2 emission from bioethanol was 97,161 kg/y and SO 2 emission was 513 kg/y which is much lower than diesel emission. The overall bioethanol production from banana stem and application of electricity generation presented the approach economically favorable and environmentally benign.

“…Over the recent years, bioethanol (C2H5OH) has developed as a renewable and biodegradable bio-energy, clear-colorless liquid and ecofriendly potential fuel [7]. Any plants producing a large amount of readily fermentable sugars can be considered as an ideal substrate for bioethanol production [20].…”

“…Yeasts are the most commonly used microorganisms which can produce ethanol concentrations as high as 18% of the fermentation broth [6]. Various types of yeast strains are available in the market worldwide and are usually used in traditional fermentation processes to produce different types of alcohol [7,8]. The well-known selected strains for this purpose are S. cerevisiea, S. eliypsoideus, S. carlbergensis, S. fragilis, and Chisovacaromycesom pombe.…”

In the last few years, ethanol is being increasingly one of most necessary and popular high-demand materials in the food industry, agriculture, medicine. It is most commonly produced from biomass such as sugarcane, corn, switchgrass, etc. The aim of this study was the isolation and identification of indigenous yeasts of the grapefruit for possible bioethanol production. 200 gr of each sample (Flame Seedless, Sultanina, Fakhri, Muscat Ottonel, Pinot Noir from Vitis vinifera species) was soaked in 500 ml water at 25°C for 14 days. After the fermentation of grape samles, 42 yeasts isolates were observed by culture in the culture medium of YPD. Among these isolated yeasts six of them were selected through their responses to high osmotic conditions and high ethanol concentration. One of the isolates was more capable of produce higher amounts of ethanol and to resistant against high osmotic conditions and high ethanol concentration, compared with other studied isolates. In continue, this strain of yeast been studied based on biochemical and morphological properties and genetically identified by the sequence of D1/D2 domain of the 26S rRNA gene and phylogenetic analysis, that was a new strain of the family of Hanseniaspora we named it as Hanseniaspora opuntiae MK 460485. This strain showed significant growth potential in high concentration of ethanol, glucose and in wide range of temperatures and pH.

“…It is expected that, by 2050 the CO 2 emission of whole world will reduce to 25% if biofuel productions are properly estimated and utilized [2]. As Bangladesh is focusing on renewable energy for upcoming decades, biofuel is a best choice besides solar, wind for harnessing energy [3][4][5][6]. According to the BPDB report, the percentage of HSD (high-speed diesel) in power generation is calculated as 8.5% [7].…”

This study outlined the potential of biodiesel production from chicken fat waste and electricity generation from biodiesel on the scenario of remote region, Kuakata, located at southeastern Bangladesh based on the cost comparison between diesel and biodiesel-based power generation by HOMER software. The main objective of this case study was to address an integrated simulation-based research outcome to manage chicken skin waste (fat) for biodiesel, generate electricity from the biodiesel and present the potential of greenhouse gas (GHG) reduction from environment by product implementation. Approximate electric load profile of Kuakata and comprehensive emission modeling for this region has been performed by fuel-switching model and RETScreen Expert software. The simulation outcomes presented that 492,695 L/ year biodiesel can be produced from chicken skin waste in Kuakata and converted into 883 MWh electricity per annum. The operating cost was 188,062 $/year, and cost of energy production was 0.214 $/kWh. The outcomes from this simulation modeling also demonstrated that the annual fuel consumption for base case is 3.7 kWh/m 2 while 1.5 kWh/m 2 is for proposed case with the reduction of 2.2 kWh/m 2 per year. The calculation and simulation results also presented 70.3% GHG reduction in the region which presented drastic drop of environmental pollution.
