Penicillium

that was Dr. Alexander Fleming, a bacteriologist at St. Mary’s hospital. He had returned to his lab to find that his improperly cleaned lab station had the mold Penicillium notatum, and the growth of staphylococcus aureus was inhibited on his plates. He took a few weeks to grow enough mold to test his findings, and discovered Penicillium notatum did in fact inhibit the growth of some bacteria. However, he did not…

throat, which is caused by the streptococcal bacteria. To cure strep, most doctors would prescribe antibiotics. However, without the discovery of penicillin, strep would still be a very dangerous infection. Penicillin is an antibiotic from the mold penicillium notam, and works by indirectly breaking down a bacteria’s cell walls. The drug prevents a protein from repairing holes in the wall, and by osmosis, water rushes in and the bacteria explodes. This quickly destroys bacterial infections,…

Although its discovery was an accident, Penicillin was one of the earliest discovered antibiotic agents. Penicillin was originally noticed in 1896, it was then re-discovered in 1928 by Alexander Fleming ,with the help from two other scientists. The question this odd discovery leaves the world wondering; how was this a accident? It all started one day in September of 1928 when, former bacteriologist Alexander Fleming went on vacation, his laboratory was not very clean or orderly. While away a…

Pectinase is one of the widely used enzymes in the food and enzyme industry. It is an enzyme group that comprises polymethylgalacturonase (PMG), polygalacturonase (PG), and pectin lysase. These enzymes are used in degradation of pectic substances, which involves deesterification and depolymerization reactions. Pectic substances are the major structural component found in plant’s cell wall and lamellae. Types of pectic substances include protopectin, pectin, pectinic acid, pectic acid and…

These include species such as Penicillium notatum and Penicillium cephalosporium. These are effective against gram-positive bacteria by inhibiting peptidoglycan synthesis (Todar,2012). There are a few types of Streptomyces including clavuligerus, cattleya, and griseus. These all work against both gram-positive…

After coming home from a vacation in 1928, Alexander Fleming saw something peculiar in one of his petri dishes. There was a ring that didn’t have any bacteria in it. This bacteria killer was called penicillium notatum, or Penicillin. While Alexander Fleming was away on his vacation, a rare mold spore landed in one of the petri dishes that Alexander left out. When Alexander came back, he didn’t notice anything right away. When a former lab assistant came by, he happened to grab the dish that…

Why did the mushroom get invited to every party? Because he was a fun-gi. Now, Mushrooms can come in many shapes and sizes, but they all belong to the same class FUNGI. What is a fungi? Is it a plant or animal? Actually, they’re neither. The mushroom are in their own kingdom, because how the gathering of food is unlike plants and animals. Plants use photosynthesis to produce food. Animals eat plants or other animals for food. But fungi draws their nutrition from decaying plants or organic…

invention that are still crucial and essential to our lives today. Without antibiotics, simple illnesses would leave many dead, as it did prior to their development of antibiotics. It was in 1928, when Alexander Fleming observed a common fungus Penicillium notatum destroy bacteria in a staphylococcus on a culture plate. From this point on antibiotics were known as the “miracle drugs” and their impact was incredible. With the development of antibiotics, it changed the field…

The mushroom is the most common type of fungi. Fungus is a fascinating organism because it is neither a plant nor animal. In some instances it appears that it has characteristics from both. Most people use to think that mushrooms were close relatives to plants, however they are not producers. This simply means that they do not make their own food. They receive their nutrients from their surroundings. They are labeled as decomposers because they break down their food and return the nutrients to…

Sick building syndrome (SBS) is the adverse, recurring symptoms that occupants experience during their time spent in a building (Khan & Karuppayil, 2012). Notably, SBS affects 19.4% of office workers (Ooi, Goh, Phoon, Foo, & Yap, 1998). Those affected experience short term ailments such as headaches, nausea, fatigue, and coughing that consequently hinder efficiency and increase absenteeism (Joshi, 2008). A common cause of SBS is the presence of bioaerosols, most notably mold, a form of fungal…
