Aspergillus Versicolor

790 Words4 Pages

Summary
The present study is concern with the assessing the effect of different mineral salts and varying urea concentration on Aspergillus sp. growth and enzyme production under solid-state fermentation (SSF). Aspergillus versicolor was screened for the production of enzyme by SSF method. The fungus was placed on potato-dextrose agar (PDA) medium, subcultured them once in a week and then incubates at temperature of 30⁰C. The role agro-wastes in the solid-state fermentation (SSF) method are as substrate. The substrate was washed and dried in the oven. Later on, sieve the substrate into smaller pieces and ground them by using an electronic blender. Placed the substrate into a plastic container. In this study, solid-state fermentation (SSF) method was used instead of using submerged fermentation (SmF). Several parameters were optimized for each agro-waste to obtain maximum enzyme yield. A few types of agricultural wastes (sago hampas, orange peels and pineapple peels) were tested as substitutes of carboxymethylcellulase (CMC) in medium for the production of cellulase and pectinase enzyme by Aspergillus versicolor. As the results obtained, it suggested that this system yields the ample amount of product but decrease the cost for the production of enzyme is capable of being achieved for the application in industrial sector.

    Methods Unknown microbial #398 went through several of tests in order to identify its characteristics when isolated from a urine sample of Doris, a 64- year old patient with a kidney infection. To identify unknown #398, must prepare a working and a reserve stock by the inoculation from a broth culture and by quadrant streaking method on a PEM and EMP plates. The following test procedures were incubated at 37°C for 48 hours for observation and identification for unknown #398. The identification of unknown #398 followed test procedures from Brown1.

    Materials and Methods To start with, the unknown bacteria # 710 broth had to be successfully isolated on an EMB and MAC agar plate. Using aseptic technique by sterilizing the wire loop with Bunsen Burner between inoculations and flaming the opening of the test tubes before inserting in the loop with the bacteria. The streaking technique used was to isolate the colonies on the agar plates. In addition, the streak plates had to be incubated in a upturned position for 24 hours in a hot temperature incubator at 37 degree Celsius. Bacteria need a favorable condition to grow in.

    In medieval siege, when conventional tactics and weapon were not sufficient, they often resorted to unconventional tactics and moves such as food poisoning, water poisoning, throwing infected dead bodies and animal carcasses into the walls of the besieged town, the kind of medieval biological warfare. In the medieval period, most of the towns were fortified, surrounded by tick and high walls. It was very difficult, sometimes even with a siege machines to enter into such a fortified town.

    There are few vegetables and fruits that turns to the color brown if their surface is exposed to oxygen. Once the veggies or fruits been exposed to oxygen, then the browning begins to appear, and electrons and hydrogen will be removed. This happens because of an enzyme called catechol oxidase. The enzyme will act on its substrate catechol to form a yellow compound which then reacts with the oxygen in the air and change into benzoquinone. The more concentration of the enzyme, the more browning appears.

    Enzymes are a form of protein that lowers activation energy and speeds up reactions as a catalyst. They are made by the stringing together of an abundant amount of amino acids and folded into a specific shape for chemical reactions. Turnip Peroxidase is the enzyme used in this lab and is derived from the vegetable. Enzymes are not used up or permanently altered by their environment Peroxidases are found in a range of organisms and function to break down alcohol (H2O2) and creates byproducts of oxygen and water. In this experiment, the reducing agent guaiacol is added with the substrate, hydrogen peroxide, to create water and oxygen.

    1% glucose, 1% maltose and 1% lactose all progressively get positive results by changing colours to reddish brown at the end of this experiment. In this case the aldehyde functional group that is present in the products (monosaccharides and some disaccharides) in this reaction is able to reduce copper in the presence of alkali and this produces colour changes while converting to an aldose sugar. Honey is made of fructose and glucose which instantly turned brown after the test-tube was placed in the boiling water because of its active aldehyde and carbonyl group. The copper (II) sulphate present in the Benedict’s solution reacts with electrons from the aldehyde group which results in a redox reaction to from cuprous oxide, a red brown precipitate that seen in all of the above mentioned solutions (Hill, 1982). Beer also gave positive results because it contains aldehydes and ketones (i.e. acetone, trans-2-butenal, furfual) during its beer production process where the sugars are converted through fermentation (Hill, 1982).

    Enzymes speed up chemical reactions enabling more products to be formed within a shorter span of time. Enzymes are fragile and easily disrupted by heat or other mild treatment. Studying the effect of temperature and substrate concentration on enzyme concentration allows better understanding of optimum conditions which enzymes can function. An example of an enzyme catalyzed reaction is enzymatic hydrolysis of an artificial substrate, o-Nitrophenylgalactoside (ONPG) used in place of lactose. Upon hydrolysis by B-galactosidase, a yellow colored compound o-Nitrophenol (ONP) is formed.

It is theorized that American soldiers brought it to the United States after World War I from Europe. When you hear the term Ringworm, you might think that an actual worm is involved with the infection, but this is not the case. Ringworm is a fungal infection that sometimes leaves a circle-like appearance.
