Raman and SERS studies of filamentous fungi
… sizes and shapes. Raman and SERS imaging of fungi via in vivo synthesis of AuNPs were used to explore cellular components of Aspergillus nidulans (A. nidulans) cell. Critical parameters including pH, temperature and metal concentration affect the sizes and shapes of the NPs. For better …

Production of antimicrobials and antioxidants from filamentous fungi
Filamentous fungi have proven throughout history to be a vast source of potential therapeutic activities. They are recognised as nutritious, highly palatable functional foods and are now widely accepted as an untapped source of potentially powerful natural products of pharmacological significance. …

The development of filamentous fungi in submerged culture
… an important effect on the subsequent growth of filamentous fungi in submerged culture. This early phase of growth does not appear to have received much attention, and it was for this reason that the author's research was started. The aggregation, germination and early growth of the filamentous …

Cellulase and related enzyme activity in protoplasts and mycelium of filamentous fungi.
… the perfect stage of Penicillium emersonii) fungi. The fungi were grown on Acetobacter xylinum cellulose pellicles and soluble carboxymethyl cellulose and their enzyme complements were characterised under various growth conditions. The factors affecting the production and release of …

Quorum sensing for improved production of industrially useful products from filamentous fungi
… bacteria in addition to unicellular fungi. Various recent studies report the presence of QS in filamentous fungi. Lipophilic molecules, including lactone-based molecules and the oxygenated poly-unsaturated fatty acids, oxylipins, are the major signalling molecules reported in …

Analysis of the sltA (stzA) gene and its orthologues in Aspergillus nidulansand other filamentous fungi
… strains showed similar sensitivities to this fungicide. Phenotypic analyses indicate that StzA does not regulate tolerance to sources of oxidative stress, non-ionic osmotic stress or components of the Cell Wall Integrity (CWI) pathway. A. nidulans StzA appears to have no role in cellulase or …

A Study of the Morphological Development of Some Filamentous Fungi in Tower Fermenter Culture, with Particular Reference to Aspergillus Niger
… some fermentations involving two dimorphic fungi, Mucor circinelloides and Mortierella rammanniana are discussed.

Geomycology: fungal bioweathering, bioleaching, bioprecipitation and biotransformation of metals and minerals
Fungi play important geoactive roles in the biosphere, particularly element biotransformations and biogeochemical cycling, metal and mineral transformations, decomposition, bioweathering, and soil and sediment formation. Fungi can apply various mechanisms to effect changes in metal speciation, …

Identification of a Novel Link between the Motor Proteins Dynein and Kinesin-1
… cargoes along cytoskeletal microtubules (MT). In filamentous fungi, these motors are important for the hyphal growth, which is characterized by localized extension at the tip of the apical hyphal cell. This type of growth requires the movement of a large number of vesicles from and to the hyphal …

The Kinetics of Mould growth in Aerobic Tower Fermenters
This study deals with the growth of fungi on low grade agricultural carbohydrate sources in tower fermenters. - The tower or tubular fermenter was chosen as the vessel in which to grow the fungi because of simplicity, ease of construction, low capital and working costs. The work carried out …

Isolation of psychrophilic halophiles from the Antarctic polar desert
… rods with few Gram positive rods and cocci. No filamentous fungi or Halobacterium spp. were observed on the media used. At 15 C there were no isolates from media containing greater than 15 percent added salt; however, counts of 1.4 x 10³ colonies per gram of soil were found at this …

Towards the total synthesis of gambieric acid A
… show antifungal activity against a variety of filamentous fungi. The purpose of this thesis is to show the progress towards the synthesis of F–J ring system of gambieric acid A. First, the large scale synthesis of I–G ring fragment using the two directional ring closing metathesis developed in …

FUSARIUM MUSAE AND FUSARIUM VERTICILLIOIDES CROSS-KINGDOM PATHOGENS: GENOMICS AND DIAGNOSTIC INNOVATION
Fusarium species comprise a diverse group of filamentous fungi that include major plant pathogens, food contaminants, and opportunistic human pathogens. Among them, transkingdom species capable of infecting both plants and humans represent an emerging challenge within the One Health framework. …

Primary characterization of genes involved in the colony development of the insect pathogenic fungus Metarhizium anisopliae /
… pathogenesis and/or asexual development in filamentous fungi. Conidial density counts and insect bioassays suggested that a Serine/Threonine protein kinase COTl homolog is not essential for conidiation or virulence. Furthermore, a choline kinase homolog is important for conidiation, but not …

Development of Fungal Bioreactors for Water Related Treatment and Disinfection Applications
… use of a bioreactor containing mycelial mats of filamentous fungi is a novel treatment technology that incorporates physical, biological, and biochemical processes to remove bacterial pathogens from influent water. Although a relatively new concept, fungal bioreactors have demonstrated the …

Investigating Physical and Chemical Interaction of Aspergillus terreus Spores for Changes in Morphology and Physiology
It has been widely reported that in filamentous fungi, spore inoculum size affects culture morphology and secondary metabolite production. The reasons for this, however, have not been investigated thus far. There are two possible explanations as to why spore inoculum size affects fungal morphology, …

Functional Analysis of Secondary Metabolite Biosynthesis-Related Genes in Alternaria brassicicola
… a NPS-like protein named TmpL is involved in a filamentous fungi-specific mechanism for regulating levels of intracellular reactive oxygen species during conidiation and pathogenesis in both plant and animal pathogenic fungi. Collectively our results indicate that small molecule nonribosomal …
