Average biomass

The average biomass concentration is defined as the product of yield of biomass and change of substrate concentrations in inlet and outlet streams. The biomass balance is ...

It is not difficult to assess the average biomass of a fish stock over many years, using data on the numbers and biomass of samples. In Black Sea anchovy, it is 284 kt in May. By November the figure doubles as a result of replenishment and of somatic increase. The average annual biomass (B) amounts to 426 kt for anchovy, 280 kt for sprat, about 36 kt for horse-mackerel, 6 kt for red mullet and 9 kt for whiting (no data are available for pickerel). Results of the studies on annual specific and absolute production in populations of the fish examined here and Px/B coefficients are given in Table 11. 

Pg C. Savanna has a total average biomass of 28.4 t/ha and represents 86.3% of the area occupied by nonforest vegetation, with a carbon stock of 0.9 Pg. 

The amount of land required depends on the tree yield, power plant efficiency, and the capacity factor. The average biomass yield was assumed to be 11.3 dry ton/hectare. The power plant efficiency is based on a dry higher heating value of 20,200 kj/kg. A power plant annual capacity factor of 86.3% was assumed. Power plant sizes of 25, 50, and 150 MW were considered. 

However, at the maturity stage after 3 months of plantation, the average height of the inoculated plants was 114 cm and non inoculated plant was 110.0 cm. The total average biomass of the aerial plants was 123.5g in inoculated and 101.5g in non-inoculated. There was an increase of 42.68% in biomass as a result of Ecorrhizal inoculation. 

The results of the Mycorrihzal inoculation in Catharanthus roseus are also equally encouraging. The average collar girth of the inoculated plants was found to be 30% more than the non inoculated plants. The average biomass in the inoculated plants was found to be 92.03% more than the non inoculated plants.

According to some authors [37, 38], in the Eastern basin in summer the average density of the Artemia population was 5-10-fold higher than that in the Western basin, 20-30 ind. 1 and 2-6 ind. respectively. However, these data were obtained only for the shallows of the Western basin. Taking into consideration the whole population inhabiting the entire water body volume of the Western basin, the difference in population abundance and biomass between the two basins was not significant. In October 2005, Artemia abundances in the eastern and Western basins were 0.95 0.65 ind. 1 and 0.65 0.27 ind. 1 , respectively. Average biomasses were similar in the eastern and western parts - 0.65 0.36 and 0.79 0.32 g m , respectively [21]. 

Assuming that cells produced in this biochemical reaction can be represented by the Roels average biomass (that is. 1 C-mole cells = CHi gOo.sNo, ). how many moles of oxygen, nitrogen, and water are consumed for each mole of carbon monoxide consumed ... 

Consider next the fermentation of some nonnitrogenous, but otherwise unspecified, substrate (for example, a sugar such as glucose) in aqueous solution with dissolved ammonia as the nitrogen source to produce average biomass, carbon dioxide, and water. On a carbon mole basis, this reaction is... 

A/n = moles of nitrogen atoms perC-mole of nitrogen source (e.g., 1 in ammonia) A/b = moles of nitrogen atoms per C-mole of biomass (e.g., 0.2 in average biomass) A/p = moles of nitrogen atoms per C-mole of product... 

The next difficulty in using the energy balance is that thermodynamic property data, such as the heat of combustion, may not be known for some identified molecular species compounds, and is not likely to been measured for incompletely defined species such as the average biomass CHi.sOo.sNo.t- To estimate the properties in these cases, we will use the generalized degree of reduction, - c. defined as follows ... 

The average biomass used to represent many yeasts and bacteria has an elemental composition, on a C-moIe basis, of CH. sOo.5No.2. Compute its generalized degree of reduction, and estimate its Gibbs energy and heat of combustion. 

When a yeast of average biomass composition is grown on an aqueous solution of methanol with dissolved nitrogen, it is found that 400 g of dry yeast are produced for each kilogram of methanol consumed. No other products are formed. Compute the oxygen consumed and carbon dioxide produced per kilogram of methanol consumed. 

The zooplankton biomasses vary in different areas and seasons. The spatial zooplankton biomass decreases from south to north the average biomasses in the north, middle area and south are 28.8, 31.7, and 74.3 mg/m, respectively. The highest value is found in summer, followed by spring, and the lowest value is in winter. In spring, the average biomasses in the north, middle area, and south are 12.9, 14.3, and 134.7 mg/m , respectively. In summer, the average biomasses in the north, middle area, and south are 50.1, 45.4, and 27.1 mg/m, respectively. In autumn, the average biomasses in the north, middle area, and...
