At a density of 10,000 and 20,000 plants per hectare, the amount of nitrogen removed annually in the harvested biomass averaged 88 kg/ha. The data suggest that 10,000 plants per hectare would produce the greatest annual biomass yields; however, research is needed to determine the nutrient ...
Manipulation of naturally occurring defense mechanisms in host plants is an effective and sustainable approach for plant disease management. Various natural compounds, ranging from cell wall components to metabolic enzymes have been reported to protect plants from infection by pathogens and hence provide ...
In still more tests, researchers noted significant differences between the plants grown in microgravity and those under regular gravity. For example, results from studying NASA's Biomass Production System (BPS) found that while the two sets of plants grew similarly, the immature seeds grown on the...
We can also utilizeagricultural matter to producebiomass. Soybeans, corn, algae, sugar cane and other plants can create fuel to power our homes, electric cars and devices. Scientists are also using refuse for energy production.Municipal solid waste, like cotton, paper, yarn and food, can trans...
Although plants account for more than 90 percent of the earth’s two trillion tons of biomass, they represent only some 20 percent of earth’s classified and named organisms. In contrast, while the animals make up only a small fraction of the biomass, they represent more than 60 percent of...
But while plants already have a head start on nickel mining, it wouldn’t be feasible to start commercial operations with them today. The most efficient known hyperaccumulators might be able to produce 50 to 100 kilograms of nickel per hectare of land each year, Kim says. That would yield ...
After glucose metabolism, dietary carbohydrates produce energy and organic acids as metabolic by-products50. The acid-producing activity ofS. mutansis not only a critical factor contributing to its pathogenicity but also a crucial characteristic leading to dental caries. Bacteria enolase, an enzyme enc...
4. Biomass change and structural growth Biomass can be allocated to growth, defence, or storage (Chapin et al., 1990), and biomass change is the mass balance between production and losses. A large part of total biomass is stored as compounds that form the structure of plants: cellulose and...

“Because plants grow in a fixed location, they can’t flee from predators or pathogens,” Zhao explained. “Instead, they’ve evolved to produce compounds that help them fight off invaders, among other functions.” Camalexin, like other plant metabolites, is synthesiz...
