Cassava peel contains carbohydrates and stores a high cellulose content so that it has a potential to be a bioethanol. This study aims to utilize cassava peel waste for bioethanol production with an alkaline pretreatment process, cellulase enzyme hydrolysis and fermentation by using Zymomonas mobilis bacteria. Alkaline pretreatment with 14% NaOH is used to hydrolyze lignocellulose. The hydrolysis optimization process enzymatically applies the Surface Response Method (RSM) to determine the optimum conditions at hydrolysis pH in the range of 2-10 and hydrolysis temperature in the range of 30-70 °C by analyzing glucose levels using the Dinitrosalicylic Acid (DNS) method and UVvis spectrophotometry instruments. Surface Response Method (RSM) is likewise implemented to decide the greatest conditions of the fermentation process. The pH measurement ranges 2-10, and fermentation time takes 6 to 168 hours. Based on the results of research, it results a lignin content of 6.68% (b/b), cellulose content of 58.4% (b/b), and hemicellulose content of 27.3% (b/b). The optimum conditions of the hydrolysis process obtained an optimum glucose level of 9.22mg/mL at pH 2 and a hydrolysis temperature of 50°C. The optimum conditions of the fermentation process use Zymomonas mobilis at pH 6 while fermentation time takes 168 hours analyzed using a refractometer produced a bioethanol content of 37.75% (v/v) and a gas chromatography produced a bioethanol content of 54.94% (v/v).","PeriodicalId":22728,"journal":{"name":"The Journal of Pure and Applied Chemistry Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136037031","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 study was aimed to determine the composition of volatile compounds in meat and bone broth from five different animals, i.e., cow (beef), pig (pork), goat, lamb, and chicken for initial identification of halal and non halal food. A preliminary test for samples of meat and bone broth was done by identifying their physical properties including pH, viscosity, and density. The volatile compounds in meat and broth samples were extracted using a solid phase-micro extraction (SPME) at room temperature and analyzed by gas chromatography-mass spectrometry (GCMS). The results revealed the physical properties of meat and bone broth, i.e., pH, viscosity, and density, cannot be used to distinguish the type of broth produced from beef, pork, goat, lamb, and chicken. Successful results for the identification were achieved through chromatogram profile of volatile compounds from meat and bone broth which show characteristics to each type of animal, and therefore it can be used to distinguish pork from beef, goat, lamb, and chicken as initial detection for halal and non halal food.

In this study, a bacterial cellulose (BC)- based polymer was modified with polyvinyl pyrrolidone (PVP) and polyvinyl alcohol (PVA). Blending the polymer host is one more approach to work on the morphology pore and electrochemical properties of polymer electrolytes. The slurry of BC is rich of fibers that contribute to forming of the pore template for solid electrolyte membrane. Polyvinyl act as material to creating pore and increases the polymer segmental ion lithium mobility. Pore morphology of BC-PVA and -PVP composite membrane homogeneously distributed by SEM observations. The presence of many pores makes the tensile strength of the BC PVA membrane lower. For solid electrolytes purposes, it does not affect battery performance but has a greater possibility for battery lifetime. The presence of pores contributes to the absorption of electrolytes membranes. In addition, enhancement of the conductivity upon addition of salt is correlated to the enhancement of pores from solid polymer electrolyte. The conductivity of BC-PVA composite is reported 8.7 x 10-5 Scm-1 , and this ion conductivity is slightly higher than conductivity in BC-PVP 8.4 x 10-7 Scm-1 at room temperature.
