With growing insight into the harmful impact of lifestyles practiced in modern societies on environment, pro-environment behavioral change has become a central focus not only environmental policy but also applied psychology. An established theoretical framework is needed to understand development environmentally friendly behaviors. The objective this study was propose social-cognitive theory perspective as one psychology theories that can be explain pro-environmental behavior. Understanding...
The development of renewable energy resources is strongly urged to recoup the shortage fossil-based and its associated pollution issues. Energy production from carbohydrate materials has recently been great interest due availability, reliability, abundance sources. Significantly, catalytic transformation waste carbohydrates into furan-based biofuels, specifically 2,5-dimethylfuran (DMF), appears be an attractive solution aforementioned environmental potential DMF as a fuel prospective, with...
Hydrogen energy is environmental-friendly and considered an attractive alternative to fossil fuels. Among the feasible technologies for hydrogen generation, photocatalysis-derived from water splitting be optimal solution meeting long-term sustainability increased demands. In this context, various photocatalytic genres are proposed, with metal carbon-supported photocatalysts demonstrating greater comprehensiveness potential addressing solar-driven production water. Several important aspects...
This study aimed to evaluate the effect of microplastics on Spirulina sp., pigment phycocyanin in and sp. degradation PE PP plastic. The interaction with microplstic (PE PP) was conducted by adding microplastic (500 mg/500 mL, a size 0.5–1 mm2) microalgae culture. optical density measured for 30 days determine growth Harvesting performed obtain dry sp biomass. Phycocyanin obtained through extraction mixing 0.1 g biomass 25 ml 1% CaCl2 an ultrasonic water bath at 50 kHz, 300 W °C 15 min....
The use of petroleum-based plastics has raised environmental issues as more plastic waste enters and accumulates in the environment. It led to development biodegradable plastics. Starch is one potential materials make plastic, but starch-based poor mechanical strength. Blending starch with poly(vinyl alcohol) (PVA) lignin expected improve properties plastic. Biodegradable films from PVA/starch/lignin blends glycerol a plasticizer were prepared using an internal mixer for compounding hot...
Abstract In the present work we identified and quantified effect of hydrodynamic stress on two different microalgae strains, Dunaliella tertiolecta D. salina , cultivated in bench‐scale bubble columns. The cell death rate constant increased with increasing gas‐entrance velocity at sparger. was slightly more sensitive than . critical velocities were ∼50 30 m s −1 for respectively. effects gas‐flow rate, culture height, nozzle diameter also studied. From these results it concluded that rising...
The increase consumption of natural substances has brought about in increasing demand on biological source, including Spirulina sp. This been recognized to provide some such as colorant, source vitamins, protein and minerals. Different material state the form fresh dried may cause different quantity quality microalgae which posses a wide range change nutritional substances. aims study was investigate bioactive compounds resulted from Spirulian sp (fresh dried) quantitatively. materials used...
Onion, a very common season ingredient, is useful as an antioxidant and optimal conditions are required for its drying while ensuring the best quality retained. This study evaluated effect of temperatures relative humidity on both rate onion quality. Onions with average diameter 20.125 ± 0.025 mm were peeled sliced into thickness 1.233 0.029 mm. They then dried 120 min under various ranging from 40 to 70 °C. Both moisture content total phenolic compounds measured analyzed responses, data...
Application of Spirulina platensis (Gomont) Geitler into food product can be used for producing functional and improve its nutritional value. However, some bioactive compounds containing in S. are heat sensitive, therefore processing techniques need to strictly considered. It is necessary observe the application powder different products ice cream soft cheese which was relatively low temperature protect from damage. contains approximately 55 % 70% protein utilization on expected Innovation...
Silver (Ag) substituted ZnO thin films were successfully deposited onto glass substrates by spray coating technique. Structure, morphology, and optical properties evaluated X-ray diffractometer (XRD), scanning electron microscopy (SEM), UV-Vis spectrophotometer, respectively. XRD spectra had polycrystalline wurtzite structure; SEM images showed that different surface morphology at Ag doping concentration. From transmittance spectra, transparency decreased as well band gap energy along with...
Phycocyanin extracted from Spirulina platenis has been linked to many food colorant and health applications. The extraction of this compound by using conventional method resulted low yield longer processing time. This research was aimed determine optimum process conditions ultrasound assisted (UAE) phycocyanin microalgae platensis. response surface methodology (RSM) employed search UAE among set variables: temperature (T=30-60oC), time (20-50 min) frequency (28-42 Hz). result showed that...
Cheese whey, is a byproduct of cheese or dairy industry, as raw material for ethanol production, because it contains 4.8% lactose. This study used Fed-batch process during fermentation. The advantage this to prevent the reduction in substrate aim examine optimum temperature operating conditions on production through fed-batch fermentation using Kluyveromycess marxianus with variations 300C, 350C, 400C respectively. Results showed that highest biomass and concentration was achieved at μ...
