Assay of Cellulolytic Activity of Molds Isolated from Fabrics and Related Items Exposed in the Tropics

The Ecology of Fungi on Plant Remains Above the Soil

“…Siu (1951) lists Cladosporium herbarum, Alternaria tenuis and Epicoccum nigrum as ha\ ing definite cellulolytic activities but not Aureobasidium pullulans. White et al (1948) assayed fungi isolated from cotton fabrics tor cellulolytic ability, by measuring decline in tensile strength of strips of cotton fabrics inoculated with the fungi, in the presence of mineral salts. Alternaria tenuis was fairly strongly cellulolytic, not all isolates of Cladosporiu?n herbarum were and none were strongly so.…”

Antagonism of Aspergillus terreus to Sclerotinia sclerotiorum

“…One very common habitat is the rhizosphere of plants (4). This species was found by White et al, (17) to be the most strongly cellulolytic species of the genus. This fungus produces a large number of specific metabolites, including the nephrotoxin citrinin, the neurotoxins citroviridin, patulin, terrain, terreic acid and geodin.…”

Ecological Life History Outlines for Fungi

“…1938, Zuck 1946); anastomosis formation between spores or mycelium ; mixture of protoplasm in monocaryotic or coenocytic cells to form coenocytic cells ; continuation of heterocaryotic cells throughout subsequent development ; vegetative spread of mycelium: area involved, speed of development; development of chemical by-products (Lochwood and Reeves 1945); use of nutrient materials (Lindeberg 1944, Sinden, Mix and Siu 1948, White et al 1948); source of nutrient materials (Lindeberg 1944, Fries 1938, White et al 1948; respiration of fungus mycelium (Darby andGoddard 1950, Scheffer andLivingston 1937) ; development of conidiophores in relation to temperature, moisture, humidity, light; chromosome numbers ; development of pigments (Raper and Thorn 1949, Thorn and Raper 1945, Higinbotham and Powers 1947 ; changes in culture medium (Lindeberg 1944, Sinden, Mix. andSiu 1948) : nutrients withdrawn from medium by fungus, substances added to medium by fungus (Lockwood and Reeves 1945), e.g., Aspergillus terrcus produces itaconic acid during period 6-12 days after spore germination in pH below 2.3 which is suboptimum for mycelial growth ; see extensive lists of literature on this subject in Thorn and Raper (1945), Raper and Thorn (1949), Foster (1949); development of sclerotia, hiille cells, etc.…”
