Fuel Characteristics and Storage
Published in Fred Hall, Roger Greeno, Building Services Handbook, 2017
The carbon cycle is a biogeochemical cycle that represents movement of elements and compounds* through living organisms and the non-living environment. During the plant growth of biomass and its subsequent combustion as a fuel, a process of carbon exchange occurs. Energy from sunlight contributes to the process of photosynthesis in plants which absorbs the carbon dioxide released into the atmosphere by biomass fuel combustion, thereby completing the cycle. As this cycle is closed, net carbon emissions are zero. Expressed another way, biomass is carbon neutral. A closed carbon cycle indicates that the world supports a fixed amount of carbon.

Environmental changes and human activities can alter the earth’s ecosystems and biogeochemical cycles, which are critical to sustaining the earth’s living environment. Ecosystems respond continuously to environmental change and variability as well as to numerous disturbances caused by human activities and natural events. Responses include changes in ecosystem distribution and extent, impacts on natural resources (e.g., food, fiber, fuel, and pharmaceutical products), ecosystem services (e.g., treatment of water and air, climate and weather regulation, carbon and nutrient storage and cycling, habitat, maintenance of water resources), and variations in fundamental processes, including exchanges of energy, momentum, trace gases, and aerosols with the atmosphere, which in turn influence climate. Vegetation properties are key elements in the study of the global carbon cycle and ecosystems. Monitoring global vegetation properties from space can contribute significantly in improving our understanding of land surface processes and their interactions with the atmosphere, biogeochemical cycle, and primary productivity.

Microorganisms play a fundamental role in ecological functions and ecosystems, acting in almost all the biogeochemical cycles. Therefore, information of its dynamics in different environmental compartments becomes essential, especially regarding to plant–microorganism relationship in the rhizosphere of a biome with selective conditions, such as Caatinga, can result in an incremented understanding of its complexity, also assisting in the conservation and preservation of these environments, as well as in the development of technologies and tools [2,3]. Atlantic Forest and Caatinga represent hotspots of biodiversity, both covering 26% of Brazilian territory, in a total of 2.14 million km². Atlantic Forest harbours 20.000 vegetal species, from which 35% are endemic species. The technological potential of microorganisms originating from Brazilian soils is still barely explored [3]. Thus, reports in the literature, as Lacerda Júnior et al. [4] and Acosta-Martínez et al. [5], highlighted the importance of Brazilian biomes as a source of biological catalysts, providing substantial data and demonstrating the predominance of Actinobacteria phylum as effective in the degradation of organic compounds [1,6,7].
Microorganism preservation by convective air-drying—A review

In recent years, this concept has been aggressively extended to the area of microbiology as while the bulk of biodiversity on the earth is dominated by microorganisms, only 10% of it has been characterized.[5] In addition, microorganisms play an essential role in recycling earth’s naturally occurring matters through biogeochemical cycle which mainly includes the hydrologic (water) cycle, carbon cycle, nitrogen cycle, sulfur cycle, and metal cycle.[6] All in all, having the preserved form of microorganism offers a wider range of applications for a substantially longer period of time as compared to its unpreserved liquid or slurry form.[7] In the area of scientific and industrial development, preservation makes it possible for various applications including observation of cells preserved on microscope slides, starter cultures for direct inoculation to fermentor or biological tank (e.g., yeasts, mesophilic mixed culture), biocontrol agents such as biopesticides and biopreservatives (e.g., Lactobacillus plantarum, Beauveria brongniartii).[8910]. Moreover, preservation has also fueled the improvement of health-related products such as tablets containing beneficial probiotics, functional supplements in food products, and in fermented food products.[8]
