Microbial biomass production on solid hydrocarbons
Folia Microbiologica, 1973Solid 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, 1991Abstract 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 Pretreatment of Biomass
2003Typical 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.

2023
The last two decades soil organic matter research developed rapidly, uncovering a central role of soil microorganisms in the sequestration and storage of soil organic carbon (C), especially through accumulation of their necromass. However, despite strong evidence that the so-called soil microbial carbon pump is an important process, the direct ...

Biomass to fuels via microbial transformations
Current Opinion in Chemical Biology, 2008The 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

The Determination of Microbial Biomass
1999Abstract 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 biomass and productivity in seagrass beds
Geomicrobiology Journal, 1985Different 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.

Indirect Estimation of Microbial Biomass
1996In soils, microorganisms occur in great density and variety. Bacteria and fungi are the most abundant microorganisms, protozoans and algae occur in smaller numbers. The proportion of carbon biomass in the soil has been found to be 1–3% of the organic carbon (Sparling 1985).
