Machine contamination. To be sure that the correct problem is addressed, all the deposits on the machine have to be examined through a microscope to identify the presence of fungi, filamentous bacteria, bacteria in zooglea, nematodes and protozoa. This will help to solve problems linked to fresh water or sprayed water. This is why areas around showers are critical for such examination and success of biocide treatment. Remember that filamentous bacteria don t grow on Petri dishes and are easier to detect using microscopy. 

Fungi. Two forms of fungi commonly encountered are molds (filamentous forms) and yeasts (unicellular forms). Molds can be quite troublesome, causing white rot or brown rot of the cooling tower wood, depending on whether they are cellulolytic (attack cellulose) or lignin degrading. Yeasts are also cellulolytic. They can produce slime in abundant amounts and preferentially colonize wood surfaces.

Mycelium A mass of filaments composing the vegetative body of many fungi and some bacteria. 

Development work has been carried out on processes to produce feed from starch effluents in non-aseptic waste treatment systems (such as oxidation ditches and aeration ponds) using amylolytic filamentous fungi. These often belonging to the genera Aspergillus and Rhizopus. In such processes, the levels of contaminating bacteria are depressed by operating the systems at low pH. 

Both fungi will grow at pH 2.5, at which non-aseptic processes can be operated (that is without sterilisation). However, the SCP grown in non-aseptic systems is suitable only as feed. The SCP from both organisms can be used as a high-protein food additive, but Fusarium sp. must be ground up (powdered) for this. In addition, the filamentous fungus can be used to make meat substitutes. For this the SCP must be prepared deep-frozen and not dried. 

False. However, it is true that only relatively few yeasts and filamentous fungi produce exopolysaccharides. 

It has been suggested that fungi grow in filamentous form at an exponential rate with a constant specific growth rate (ji) until some substrate becomes growth limiting, according to the Monod equation 4 6... 

For example, a screening of 416 strains (71 bacterial strains, 45 actinomycetes, 59 yeast, 60 basidiomycetes, 33 marine fungi, and 148 filamentous fungi) has been performed to look for microorganisms that display reductase activity in the absence of oxidase activity [8b]. A new microorganism, Diplogdasinospora grovesii IMI... 

All three of these are dermatophytes, i.e. filamentous fungi which can utilize keratin for their nutrition. Keratin is the chief protein in skin, hair and nail. Hence, all of these organisms are responsible for superficial mycoses in mammals. It is often stated that dermatophytes are the only fungi to have evolved which rely upon infection for then-own survival. This mistaken belief results from a view which is too human-centred and neglects, for example, the presence of symbiotic fungi in the stomachs of ruminants. 

Typical of fungi, the organism grows as branching filaments (hyphae) and by the time that the culture has progressed to the production stage it has a soup-like consistency.

Pectin degradation requires fee combined action of various enzymatic activities. However, evaluation of fee contribution of individual pectinases in Suit juice extraction and clarification is rather complicated. Most commercial pectinolytic enzyme preparations are produced by fermentation wife filamentous fungi, mostly strains belonging to fee genus Aspergillus,. plication studies with mixtures of isolat enzymes obtained by fermentation or by means of fractionation of commercial enzyme preparations can be used to assess the importance of fee various individual enzymes. Subsequently, molecular biology and fermentation technology can be used to enhance specific desirable enzymatic activities.
