Define biomass in terms of photosynthesis reaction?4 answersBiomass, in the context of photosynthesis, refers to the organic materials produced through the conversion of carbon dioxide (CO2) and water into organic chemicals using solar energy absorbed by plant pigments. This process, known as photosynthesis, involves the reduction of CO2 and the oxidation of water, resulting in the generation of sugars as initial organic products. Biomass growth through photosynthesis is a fundamental process that utilizes solar energy to convert inorganic materials into a variety of organic compounds, including polysaccharides, lipids, proteins, and other complex organic molecules. The production of biomass via photosynthesis can be enhanced by utilizing microorganisms in a nutrient solution saturated with CO2 and illuminated under controlled conditions. Additionally, the use of microalgae irradiated with light in an aqueous substrate enriched with CO2 can lead to the efficient production of biomass for various applications.
What are the Characteristics of bioreactor design?5 answersBioreactor design encompasses various crucial characteristics. It involves creating an ideal environment for microorganism growth and product formation. Bioreactors can be categorized based on the physical state of the substrate into submerged and solid-state reactors, each requiring specific design considerations. The design aims to mimic the native tissue environment in tissue engineering applications, focusing on mass transport, physiological signaling, flow rheology, and cell microenvironment. Additionally, bioreactors play dual roles as reaction vessels and microorganism growth chambers, emphasizing the importance of careful consideration in their design. Incorporating factors like mass and heat transfer, fluid dynamics, and nutrient supply through valves is essential for optimal bioreactor performance. These characteristics collectively contribute to efficient bioreactor design for various applications.
What is biomassa?5 answersBiomassa refers to organic materials derived from plants and other biological sources, which can be utilized for energy production through various processes like combustion, thermochemical, or biological methods. It consists of renewable raw materials such as forest residues, agricultural by-products, and urban waste, which can be converted into sustainable energy sources. Biomass plays a crucial role in supplying energy globally, accounting for about 10% of the world's energy demand and significantly supporting developing countries. In Brazil, biomass sources like sugarcane, wood, and other renewables contribute significantly to the country's energy matrix, with sugarcane being a key player in ethanol production and bioelectricity generation. The utilization of biomass is expanding beyond energy production to applications like electrochemical supercapacitors, showcasing its versatility and potential in various sectors.
What the parts of bioreactor?3 answersA bioreactor typically consists of several parts. These include a vessel with a central axis, at least one wall, and media conduits for fresh or spent media circulation. Bioreactor systems may also include fluidically coupled vessels, fluidic paths for culture medium flow, fluid transfer devices, and a control system for maintaining uniform values of parameters in the culture medium. Another type of bioreactor includes a container with a side wall, bottom wall, and an opening closed by a cap, along with an intermediate wall dividing the inner chamber into upper and lower chambers. Additionally, a bioreactor may have a housing, fluid dispensers, and a scaffold for applying different fluids to different regions. Finally, an intensive process bioreactor for growing aerobic microorganisms may include a housing, heat exchange jacket, stirrer shaft, gas dispersion discs, rotatable baffles, defoaming disc, waste air outlet, culture fluid supply connection, culture fluid recirculation pump, and bubbler.
What are the definitions for biomass?5 answersBiomass refers to all non-fossilized biological materials, including forest residues, agricultural residues, energy crops, industrial residues, food wastes, municipal wastes, animal residues, and algal residues. It is a renewable source that is used for energy and non-energy purposes, such as fuel and power production, agricultural and industrial uses, and even for energy storage, sensors, and catalysis applications. Biomass is defined as any organic matter that is available on a renewable basis, including dedicated energy crops and trees, agricultural food and feed crop residues, aquatic plants, wood and wood residues, animal wastes, and other waste materials. It is the term used to identify organic matter generated from waste or living plants, such as trees, grass, and agricultural crops and residues.
What are the different biomass definitions in the literature?5 answersBiomass has different definitions in the literature. It can refer to organic materials found in the biosphere, including agricultural and animal wastes, as well as renewable organic materials such as wood, urban wastes, and aquatic plants. The definition of biomass can also vary based on its purpose of use. It can encompass all living and dead organisms, along with their wastes, including the three domains of life - Archaea, Eukarya, and Bacteria. From an energetic perspective, biomass is any renewable resource from organic matter that can be used to produce energy. The Oxford Concise Dictionary defines biomass as the total quantity or weight of organisms, but it typically excludes materials like oil, natural gas, tar sands, and coal. Overall, the various definitions of biomass can lead to different interpretations and calculations of its total mass or quantity.
