Biomass

practical joke (there are no real life mechanisms for a zombie apocalypse), it did call to attention serious observations concerning the detection of decompositional biological activity on habitable planets. The mountain of research concerning global biomass decay could have huge ramifications for the detection of life elsewhere in the Milky Way galaxy. The first major aspect of this approach concerns the underappreciated biodiversity of detrivorous bacteria. Most…

located in the Indian Ocean. Biomass burnings alter the optical depth in Africa, whereas volcanic activity is responsible for the variations in optical depth on Reunion Island. According to the graph, biomass burnings create a greater fluctuation in optical depth than volcanic activity. This could be because the emissions from biomass burning can quickly dissolve in the atmosphere, whereas volcanic ash takes months to clear up. A scientist would graph data of biomass burnings and volcanic…

gas as well as oil power. The traditional sources of energy are definitely environmentally unfriendly. Alternative energy has several other names such as clean energy, green energy, or renewable energy. Alternative energy includes geothermal power, biomass, hydropower, solar power, and wind…

It reached the maximum biomass of 2.32 g/L at 36 h and then the growth was retarded. Obtained final biomass was 1.32 fold higher than linoleic acid that produced maximum amount of PHA. Finally it yields 0.32 g/L of PHA with 14.8% PHA content from the resulting biomass which is lower than other carbon sources employed in shake flask cultivation. Polymer strongest band carbonyl ester also seen in…

summer crop and sequestering these nutrients until the spring when they can be returned to the soil at the start of the summer growing season. Winter cover crops lessen sedimentation by reducing erosion and the accumulation of nitrogen in aboveground biomass resulted in the reduction of nitrogen runoff (Prabhakara et al.,…

useful thermal energy of the fossil fuels and that of the substitute biomass fuels. To displace one liter of fuel oil, 3−4kg of biomass fuel will be required or an ETC solar collector area of 0.003 m2 will be required. Reduced cost of fuel: Taking the Kombolcha case as an example, 100% fuel oil replacement would represent 47t of biomass fuel per day. Assuming the average cost of biomass briquettes to be 108US$/t, the total year biomass fuels cost would, therefore, be approximately US$ 5,030.…

However, an important variable of vegetation is its floristic diversity and dominance. Ecological value of the plant species (IVI) influences in a great extent the biomass of an ecosystem and hence carbon stocks. Importance Value Index (IVI) is a measure of how dominant a species is in a given forest area. It is a standard tool used by foresters to inventory a forest. Foresters generally do not inventory a forest by…

that the change in biomass of pea plant species was higher under Rhizobia + fertilizer. Pea plant species comes from a legume family. According to Taiz and Zeiger (2010), these plant species enter into a symbiotic relationship with root-nodule bacteria, referred to as Rhizobia. Based on the results, the increase in biomass under rhizobia+ fertilizer is strongly influenced by the symbiotic relationship of pea with nitrogen fixing bacteria (Franche et al., 2009). Change in biomass under Rhizobia…

wastewater treatment (Adams, K, & M, 2002). In waste treatment, filtration is used to remove the contaminants so that it can be reused again while in water treatment it purifies the water for portable use. Bio-filter is where filters are attached to biomass on the filter media. The success of bio-filter has been seen in the water, air and waste-water treatment. The process has been used since 1893, and it has been effective in both industrial and domestic water treatment. In the past, water…

CHAPTER 1 INTRODUCTION 1.1 Lignocellulose Lignocellulose is the major component of biomass that has been generated through various agricultural practices, forest and industry (Anwar, Gulfraz and Irshad, 2014; Collard and Blin, 2014). It can be used as primary or secondary energy source to produce biofuel (Zeller and Grass, 2007). Table 1.1 illustrates the various sources of lignocellulosic biomass from the several sector with some examples. Lignocellulosic materials consist mainly of three…
