J. Sanderman, R. Amundson, in Treatise on Geochemistry, 2003. A unicellular or small multicellular organism including bacteria, protozoa, some algae and fungi, viruses, and some worms, esp. Secondary Processing of Microbial Biomass: ADVERTISEMENTS: Secondary processing includes the recovery of biomass from the fermentor, concentration, and drying, as well as other processes designed to sterilize the material or to fractionate it. Isolation of microbial biomass Bacteria, yeast, and algae are produced at high scales as protein sources such as human and animal food SCP are considered a good source of animal feed. This amount of N is similar in magnitude, and partly equivalent, to the amount of N contained in microbial biomass (Anderson and Domsch, 1980). Authors: Fran Hoyle (Department of Agriculture and Food, Western Australia), Daniel Murphy (The University of Western Australia) and Jessica Sheppard (Avon Catchment Council). Soil microbial biomass is considered the most labile organic N fraction in soil (Smith and Paul, 1990), and may produce or consume NH4+ and NO3− (Brookes, 2001). Microbial biomass carbon (MBC) represents the living SOC fraction and has been studied extensively. The chloroform fumigation extraction (CFE) method involves the extraction and quantification of microbial constituents (C, N, S, and P) immediately following CHCl3 fumigation of the soil (Brookes et al., 1985). Hoyle FC and Murphy DV (2006b) Seasonal changes in microbial function and diversity associated with stubble retention versus burning. The balance between production (i.e., net N mineralization) and consumption (i.e., net immobilization) depends on substrate availability, abiotic factors such as wetting and drying that affect the size and activity of the microbial biomass, as well as biotic conditions that affect the turnover and size of the standing stock biomass (Geisseler et al., 2010). Microbial biomass is a measure of the weight of microorganisms in soil. Microbial biomass C in the same plots had increased from 100 to 150 kg-C/ha (Hoyle et al., 2006a). Many “novel” fermenters have been designed for SCP processes and these are considered in more detail in Chapter 7. cro′bic adj. ScienceDirect ® is a registered trademark of Elsevier B.V.

Selling in bulk ceased in 1985 (Sharp, 1989) and the 3000 m3 vessel was eventually demolished. This leaves the microbial biomass ‘starved’. An enormous amount of research has been conducted into the use of hydrocarbons as sources of carbon for biomass processes; the hydrocarbons investigated being methane, methanol, and n-alkanes. 34 Living fungi such as Anabaena variabilis were found to be effective for the removal of two reactive dyes (C.I. The low resolution of this technique may explain the inconsistent results from similar studies. Two different approaches are based on CO2 evolution. An estimated 1–4% of the soil organic N is mineralized annually and potentially available for crop uptake (Anderson and Domsch, 1980).
