Fungi indicators

Brown The determinations of size of the cell-wall capillaries and the cellulases of fungi indicate that the enzymes that have been isolated to date are so large that they probably can penetrate only a few cell-wall capillaries in wood and cotton. This conclusion is supported by Cowling s DP data for the action of the white-rot fungus, Polyporus versicolor, on wood (Figure 13). But it is also contradicted by the same type of data for the effect of both the brown-rot fungus, Poria monticola, on wood (Figure 13) and of Myrothecium verrucaria on mercerized cotton as shown by Selby (60). Thus we believe that the catalysts responsible for the initial depolymerization of cellulose in wood and cotton by these two... 

The recent work carried on by Boulard in France on the production of alcohol from starch by the action of certain alcohol-producing fungi indicates a new method of approach from which apparently much may be expected. By the action of these new agents it is claimed that starch may be converted directly into alcohol, although... 

Dennis (1960), with reference to nonlichenized fungi, indicates that the bitunicate type of ascus generally has a short stalk and contains colored spores which are multiseptate or muriform. However, Richardson and Morgan-Jones (1964) illustrate that in lichens neither of these criteria can be applied. Indeed, they agree with Groenhardt (1962) that one can only be sure the ascus is bitunicate if both endoascus and exoascus can be shown separately and this is rarely possible in lichens. 

Most peptide antibiotics have been isolated from Jictinomycetes and especially from Streptomjces. Many P-lactams, however, and a few other useful peptide antibiotics have come from fungi. These streptomycete and fungal peptide antibiotics include many stmctural types having varied therapeutic indications and/or scientific appHcations. 

Microbiological analysis of material removed from corroded areas showed high aerobic and relatively high anaerobic counts (Table 6.7). Fungi counts were also elevated, indicating relatively high die-off of aerobic bacteria that is, the coolant was approaching its useful life.
