How different temperatures effect the amylase enzyme activity?5 answersDifferent temperatures have varying effects on amylase enzyme activity. Research on Telescopium telescopium showed that the energy of activation for amylase remained consistent between 40-60°C, peaking at 10-20°C, with a Q10 value increase of 0.065 at 10-20°C. In rice varieties, enzyme activity increased with rising temperatures until denaturation occurred, with optimal activities at different temperatures for each variety. Psychrophilic enzymes exhibit lower activation enthalpies and entropies, adapting to cold temperatures. Enzymes in fungal isolates like Aspergillus niger and Aspergillus flavus showed varying amylase activity at different temperatures, indicating the influence of temperature on enzyme production and growth. Overall, temperature plays a crucial role in modulating amylase enzyme activity across different organisms and environments.
What are the effects of biogas slurry irrigation on soil nutrient availability and crop growth?5 answersBiogas slurry irrigation has several effects on soil nutrient availability and crop growth. The application of biogas slurry alone significantly increases the accumulation of certain heavy metals in soil and crops, such as As, Cd, Cr, Cu, and Zn. Additionally, the combined application of biogas slurry and chemical fertilizers can increase soil total nitrogen (TN), microbial biomass nitrogen (MBN), and soil organic matter (SOM) levels, leading to improved crop yield. Biogas slurry also enhances soil nutrient content and microbial activity, with the nutrient content increasing with higher application rates. Furthermore, substituting biogas slurry for chemical fertilizer can improve soil physiochemical properties, such as pH, organic matter content, and water holding capacity, while increasing crop yield. Overall, biogas slurry irrigation can positively impact soil nutrient availability and crop growth, but the specific effects may vary depending on factors such as heavy metal accumulation, application rates, and the use of chemical fertilizers.

What biogas can produce?5 answersBiogas is a renewable energy source that is mainly composed of methane gas and carbon dioxide, along with other gases such as hydrogen, nitrogen, and traces of hydrogen sulphide and ammonia. It is produced through the decomposition of organic matter, such as food or animal waste. Biogas can be used in various applications, including cooking, electricity generation, heat production, and some agricultural uses. It can also be used as a replacement for fossil fuels, such as LPG, in order to meet energy needs and reduce environmental pollution. Additionally, the byproduct of biogas production, known as digestate, can be used as a valuable fertilizer. Biogas production technologies and potential feedstock are continuously being explored to further enhance the sustainability of this renewable energy source.
