Abstract

Bacterial nanocellulose (BNC) is a unique biopolymer with remarkable purity and material properties that distinguish it from plant-derived cellulose by its absence of lignin and hemicellulose. Recent research has focused on using organic waste materials as alternative substrates to reduce the cost of BNC production. This study examines the efficacy of Siwalan neer and sugarcane molasses as novel media for cultivating Komagataeibacter xylinus by comparing their performance with that of Hestrin and Schramm (HS) medium. The BNC harvested from these alternative media was rigorously characterized using scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and Thermogravimetric Analysis (TGA) to evaluate its structural and thermal properties. Notably, the use of Siwalan neer and sugarcane molasses as growth substrates enabled K. xylinus to produce BNC at a yield of 3.83 g/L, significantly exceeding the yield from the HS medium, which was 1.46 g/L. These findings highlight the potential of leveraging alternative substrates to enhance BNC production yield, cost-effectiveness, and environmental sustainability.

Abstract

This paper examined the wastewater production attributed to the solvent-based cooking oil extraction using Aspen Plus simulation facilitated which has been confirmed by experimental results. Distillate condensates that had remaining solvents as well as free fatty acids (FFAs) were identified as waste streams. Three feedstocks were tested, Crude Nyamplung Oil (CNO), high-FFA Crude Palm Oil (CPO-acid), and regular Crude Palm Oil (CPO-regular). CNO generated 0.288 t/h of hexane and methanol traces of wastewater, whereas CPO-acid (1.338 t/h) and CPO-regular (1.419 t/h) contained ethanol. The stoichiometric oxidation was used to estimate chemical oxygen demand (COD), whereas FFA content was used to determine oil and grease (O&G). The COD values of untreated streams were 293.236 mg/L (CNO), 2511.39 mg/L (CPO-acid), and 1662 mg/L (CPO-regular), which were higher than the Indonesian standard (350 mg/L). Oil and Grease (O&G) values of the untreated waste streams were not met the standards. Solvent based processes are less polluting as compared to refinery effluents (COD >15000 mg/L, O&G 4000mg/L), yet not in compliance with COD. Solvency and FFA value to biodiesel or PFAD are suggested to be enhanced to decrease the environmental burden.

Abstract

Food-grade lubricants are important in the food industry because they maintain the efficiency and safety of the production process. Halal and haram aspects in Islam are essential in food-grade lubricants because of potential contamination of lubricants in food products. The halal or haram status of a lubricant is determined by the raw materials, manufacturing process, and potential contamination of food-grade lubricants. Some food-grade lubricants use animal-derived raw materials such as stearic acid. The primary source of raw lubricant material is the animals used. The use of prohibited animals will change the status of lubricants to haram. In addition to raw materials, lubricant production can use non halal materials such as alcohols and catalysts. If the catalyst and alcohol used are not in accordance with SNI 99004-2021, then food-grade lubricants cannot be halalised. Lubricants can also be contaminated by L. monocytogenes. The infections caused by these bacteria are health hazards, especially for humans with weakened immunity. This potential surely causes harm to humans and can affect the halal status of lubricants. Due to the critical need for halal lubricants, the oil and gas company PT Pertamina has initiated the existence of five halal-certified lubricants in Indonesia: FG-GO 150, FG-GO 220, FG-GO 320, FG-GO 460, and FG-HO 46.
