The estimation of microbial biomass

Biosensors, 1985
Methods that have been used to estimate the content, and in some cases the nature, of the microbial biomass in a sample are reviewed. The methods may be categorised in terms of their principle (physical, chemical, biological or mathematical/computational), their speed (real-time or otherwise) and the amount of automation/expense involved.

Microbial biomass and productivity in seagrass beds

Geomicrobiology Journal, 1985
Different methods for measuring the rates of processes mediated by bacteria in sediments and the rates of bacterial cell production have been compared. In addition, net production of the seagrass Zostera capricorni and bacterial production have been compared and some interrelationships with the nitrogen cycle discussed.

The Determination of Microbial Biomass

1999
Abstract The soil biota represents 1-3% of the soil carbon and 3-5% of soil nil trogen. The microbial component, often ranging from 100 to > 1000 µ,g C g-1, is usually considered to contain those soil organisms not visible without magnification. It includes nematodes, protozoa, filamentous and yeast forms of the fungi, microalgae,

Microbial Pretreatment of Biomass

2003
Typical pretreatment requires high-energy (steam and electricity) and corrosion-resistant, high-pressure reactors. A review of the literature suggests that fungal pretreatment could potentially lower the severity requirements of acid, temperature and time.

Microbial biomass production on solid hydrocarbons

Folia Microbiologica, 1973
Solid hydrocarbon utilizing bacterial isolates were screened and the strains were examined for biomass production, growth on different solid hydrocarbons, protein contents, and amino acid composition. Conversion rate of solid hydrocarbon to biomass was 40–100 per cent depending on the substrate used. Linear growth curves were obtained in all cases.

Microbial communities, activity and biomass

Agriculture, Ecosystems & Environment, 1991
Abstract We present an overview of numerous methods for identification and enumeration of diverse bacterial and fungal species. These include plating, isolation on plant debris and a variety of observational methods. To integrate our efforts with the overall theme of soil ecology, we examine a range of techniques for determining microbial biomass ...

Microbial Hydrocarbon Formation from Biomass

2017
Fossil carbon sources mainly contain hydrocarbons, and these are used on a huge scale as fuel and chemicals. Producing hydrocarbons from biomass instead is receiving increased attention. Achievable yields are modest because oxygen atoms need to be removed from biomass, keeping only the lighter carbon and hydrogen atoms.

The adsorption of chloroethanes by microbial biomass

Water Research, 1986
Abstract The adsorption isotherms of halogenated aliphatic hydrocarbons by various selected types of inactive microbial biomass were determined. The isotherms were shown to be independent of the initial organic solution concentration and could be described by a modified Freundlich adsorption equation.

Biomass to fuels via microbial transformations

Current Opinion in Chemical Biology, 2008
The conversion of biomass to fuels is advancing on two fronts: first, to enhance the usability of biomass and second, to generate the best fuel molecule(s). Lignin generally presents a barrier to biomass utilization; this problem may be circumvented by the genetic alteration of lignin-producing plants. Plant cellulosic material will need to be utilized
