Herbicide management alters fungal biomass and community composition in Great Lakes coastal wetlands
… understand how herbicide management alters soil fungal communities. We assessed microbial and fungal biomass, fungal community composition, greenhouse gas emissions, soil physiological profiles, and decomposition rates. Fungicide treatments of the substrate induced respiration assays had …

Studies on fungal biomass and activity associated with the decomposition of plant litter in freshwater
… for fungi, gave higher estimates of fungal biomass than other staining methods and it correlated well with the agar film technique. Using the method, it was possible to examine the spatial distribution of hyphae on leaves which varied between leaf types and fungal species. …

An Evaluation of Palm-Oil Milling Effluent Treatment by Fermentation to Produce Animal Feed Protein
… has been developed which produces a high protein fungal biomass, as an animal feed, to offset treatment costs. The viability of the 'Malima' system was found to depend on the value of the fungal biomass as an animal feed. Therefore the evaluation of the fungal biomass as a protein ingredient …

The influence of fungi upon soil structure and soil water relations
… The impact of an arbuscular mycorrhizal (AM) fungal exudate glomalin (a glycoprotein), proposed to be hydrophobic was assessed for a correlation with low levels of soil hydrophobicity through measures of subcritical water repellency. Initially no correlation was reported but a further temporal …

Microbial activity on wood in streams: exploring abiotic and biotic factors affecting the structure and function of wood biofilms
… surface to wood buried beneath the streambed, fungal hyphae dominated the biofilm but actinomycetes and bacteria were also present. An assay of microbial activity (¹⁴C glucose uptake) indicated that surface biofilms were more active than biofilms on buried wood. There was no relationship …

Biosynthesis of Utilizable Microbial Biomass in the Treatment of Milk Wastes in High-Rate Filters
The feasibility of producing utilizable microbial biomass while treating dairy wastes in a pilot-scale high-rate Flocor tower was examined. The literature on different methods of utilizing organic wastes and on the growth and control of fungi in bacteria beds was reviewed. A survey of dairies using …

Genetic And Temporal Variation In Resource Exchange Between An Ectomycorrhizal Fungus, Rhizopogon Occidentalis, And Seedlings Of Pinus Radiata
… of C respired by fungi and C assimilated in fungal biomass to the amount of N and P assimilated in plant tissues over a time period. Resource exchange was assessed at 8, 16, 32, and 64 weeks after inoculation for two Pinus radiata native populations. Resource exchange increased over time …

The Role and Contribution of Saprotrophic Fungi during Standing Litter Decomposition of Two Perennial Grass Species, <i>Schizachyrium scoparium</i> and <i>Schizachyrium tenerum</i>
<p>In terrestrial ecosystems, most of the plant biomass produced enters the detrital pool, where microbial decomposers colonize, enzymatically degrade, and assimilate plant litter carbon and nutrients in amounts sufficient to bring about the decomposition of plant litter. Here, I estimated the …

Response of a cave aquatic community to groundwater pollution
… Amphipods were absent from all disturbed sites. Fungal biomass, total organic matter (TOM), and bacterial biomass in pool sediments were measured to determine changes in food availability caused by the septic system effluent. Fungal biomass was negligible in all pools. Contribution of bacterial …

Influence of Varying Inorganic Nutrients Supply on Ergosterol and Glucosamine Concentrations and Biomass Nutrient Stoichiometry in Ectomycorrhizal Fungi
… of increased atmospheric CO<sub>2</sub>. Six ECM fungal species were grown in liquid culture under varying nitrogen and phosphorus concentrations and ratios to assess how exogenous nutrient supplies affect fungal biomass stoichiometry and the degree of elemental homeostasis. Additional studies …

Oxidative stress and nitrosative stress, their interaction and implications for bioprocessing
… and nitrosative stress and online monitoring of fungal biomass growth in submerged batch cultures of the filamentous fungus Aspergillus niger B1-D, modified to secrete lysozyme. The results of the undertaken studies described here show that increasing concentrations of polymyxin B, added to a …

Stress-induced alterations in ecosystem function: the role of acidification in lotic metabolism and biogeochemistry
… of differing pH revealed greater rates of fungal biomass-specific respiration (i.e. the stress metric <i>q</i>CO₂) and biomass-specific N uptake (i.e. <i>q</i>N) with increasing acidity. The positive relationship between <i>q</i>CO₂ and <i>q</i>N indicated alternate fates for N other than …

The Breakdown of Plant Cell Biomass by Fungi
… indicated contained the necessary nutrients for fungal growth. Incubated in a suitable manner all three fungal species were able to grow on C. roseus and D. carota plant cell biomass in addition to material which had undergone methanol extraction or a re-autoclaving process to remove soluble …

Fungal Flora of a Cove on Lake Falcon
… end of Falcon Lake was conducted to identify the fungal flora associated with submerged plant substrates. The substrates included stems of Arundo donax, Prosopis glandulosa, and Salix nigra which were collected monthly. The leaves of Salix nigra were also collected monthly for observed Aquatic …

Role of iron in the accumulation of glomalin, an arbuscular mycorrhizal fungal glycoprotein
… of glomalin, an arbuscular mycorrhizal fungal glycoprotein, were examined. In a preliminary experiment comparing available (FeEDDHA) and unavailable iron (hematite), low amounts of glomalin were produced with the former while the latter total inhibited the symbiosis. Part of the effect …

The Kinetics of Mould growth in Aerobic Tower Fermenters
… the production of large amounts of protein rich biomass. The nutritional aspects of the fungal end product was studied, in particular the concentrations of amino acids in the mycelium. Conclusions were therefore reached as to ‘the suitability of the system and the fungus for the production of …

Lipid Biomarkers for Marine Fungi
… little is known about their global abundance and biomass, fungi are yet to be included in biogeochemical models. <br/>Lipid biomarkers can be used to assess microbial abundance and biomass due to their specificity and may be utilised to explore the viability and trophic dynamics of marine …
