A relatively rare, opportunistic infection caused by saprophytic moulds of the species of Rhizopus, Mucor and Absidia. This is often caused by Aspergillus fumigatus, and occurs mostly in severely immunocompromised individuals with serious underlying illness Allergic alveolitis follows particularly in heavy and repeated exposure to a large number The disease results following overgrowth of these commensal yeasts in association with 3 Treatments of allergic forms of aspergillosis include Use of corticosteroids By surgical incision Intravenous amphotoricin B ketoconazole and itraconazole 4 Which of the aspergillosis infection has poor prognosis? Invasive aspergillosis Allergic aspergillosis Aspergilloma All of the above 5 Which fungus is a primary resource for wine production? Aspergillos Mucor Saccharomyces cerevisiae Coccidiodis immitis 6 What is the primary role of the fungus in wine production? Is the fermentation that converts the MUST into wine In fermentation that convert the sugar into wine In fermentation that convert the glucose into wine In fermentation of the soluble sugars (Glucose and fructose) of the juices of grapes into ethyl alcohol and CO2. 7 A nutritive use of fungi is Biomass utilization of bacterium digesting Yeasts are the principal organisms that have been used and the generic name for the Use of fungus in growing vegetables Use of fungi as a single cell protein as a supplement for animal feed 8 What is leaving of bread? Addition of sugar to the dough The entrapment of Crarbon Dioxe produced during fermentation to cause the dough to rise Fermentation of sufficient sugar Moisturized flour is mixed with yeast 9 Define Saccharification Fermentation process by yeast to hydrolyzing the starch into maltose and glucose Fermentation process by yeast to hydrolyzing the starch into ferns and glucose Fermentation process by yeast to hydrolyzing the starch into malt and glucose Fermentation process by yeast to hydrolyzing the barley into maltose and glucose 10 How is malt formed? Grains are allowed to germinate to form amylase, then dried and Grains are allowed to germinate to form amylase, then dried and Grains are allowed to germinate to form amylase, then dried and All of the above 11 What is a fruiting body? Subterranean mycelium that grows outward to differentiate in pileus which houses Subterranean mycelium that grows outward to differentiate in pileus which houses the Subterranean mycelium and grows outward to differentiate in pileus which houses the Subterranean mycelium that grows outward to differentiate in pileus which houses the 12 The following are sequences of production of wine The grapes are harvested, they are crushed to produce a raw juice or must The mixed yeast flora on the grapes serves as the inoculums for the fermentation that convert the must into wine The MUST is first treated with sulphur dioxide (SO2) to eliminate the natural yeast flora All of the above 13 Red wine are produced By fermentation of red grapes with skin By fermentation of red grapes without skins By addition of flavours to must By removal of skins of red grapes 14 How is wine spoilage prevented? By addition of lactic acid By addition of flavours By additing sulphur dioxide By removing the skin 15 How is barley saccharified? Barley is dampened, allowed germinate and mixed with sulphur dioxide Barley is dampened, allowed germinate and used Barley is dampened, allowed germinate, and filtered Barley is dampened, allowed germinate, and is then dried and stored for subsequent 16 Light beer is produced When unmalted grains are used When malted grains are dark When both unmalted and malted grains are mixed When unmalted grains germinate 17 The antibiotic isolated from Streptomyces griseus is Tetracycline Streptomycin Chloramphenicol Erythromcin 18 Of the antibiotics listed in 77 above, which was isolated from Streptomyces venezuelae? Tetracycline Streptomycin Chloramphenicol Erythromcin 19 In what year was penicillin discovered? 192 1929 2019 2109 20 Who is the discoverer of penicillin? Alexander Fleming Edward Jenner Ian Fleming James Bond
