How to make alcohol from potato starch?5 answersTo produce alcohol from potato starch, the starch needs to be converted into fermentable sugars through processes like hydrolysis before fermentation with yeast to yield alcohol. Various studies have focused on utilizing potato waste as a renewable carbon source for ethanol production. The conversion of potato starch into glucose is cost-effective, and fermentation with Saccharomyces cerevisiae yeast yields significant ethanol amounts. Hydrolysis of potato starch waste with acid solutions liberates fermentable sugars, leading to bioethanol production. Optimal conditions for fermentation include pH 5, 30°C, and 100 rpm, resulting in high bioethanol yields. Additionally, microwaves have been used for gelatinization and saccharification of potato wastewater, followed by fermentation with Saccharomyces cerevisiae, resulting in efficient alcohol production.

What are the different types of products that “white” biotechnology can develop?4 answersWhite biotechnology can develop a variety of products. These include food additives, flavorings, essential amino acids, poly-unsaturated fatty acids, organic acids, and gelling agents, which can be obtained from microbial sources. Microbes also produce primary metabolites such as vitamins, nucleotides, and amino acids, as well as secondary metabolites that are used to make drugs. In addition, white biotechnology can be used to produce fertilizers and biological pesticides for agriculture. Furthermore, white biotechnology can contribute to the development of biodegradable consumer goods, such as fabrics and plastics, that are easily degradable, require less energy, and create less waste during production. Overall, white biotechnology offers a wide range of products with applications in the food, pharmaceutical, agricultural, and consumer goods industries.
Why moon is white?5 answersThe moon appears white due to the phenomenon of luminance anchoring within the visual scene, as explained by the double-anchoring model of lightness. This model states that the shade of grey, or lightness, of any given region is computed by taking a weighted average of the ratios of the region's luminance to two anchors: the surround luminance and the highest luminance in the scene. At the highest-luminance anchoring stage, the moon is always perceptually white, regardless of its actual luminance. However, at the surround anchoring stage, the moon can appear lighter than white, giving it a glowing appearance, depending on its luminance ratio to the surrounding sky. Therefore, the moon's white color is a result of the anchoring of its luminance within the visual scene.
Nanotechnology in agriculture?5 answersNanotechnology is being applied in agriculture to improve crop yield, enhance nutrient absorption in plants, and combat crop pathogens. Nanoparticles are used to release pesticides and fertilizers at specific times and targeted locations, reducing damage to other plant tissues and minimizing chemical release into the environment. Nanotechnology also offers the potential for molecular treatment of diseases, rapid disease detection, and the development of new crop and animal traits. Additionally, nanotechnology is being used to create intelligent packaging in the food industry, which can monitor air and moisture changes, indicate spoilage, and improve food quality. However, the use of nanomaterials in food and agriculture raises concerns about their potential impact on human health, such as DNA injury and the possibility of cancer cells. Regulation, legislation, and consumer awareness are important for the safe and responsible use of nanotechnology in the food and agriculture sectors.
