Microbes are single-cell organisms that cannot be seen by the naked eyes and are found everywhere in the ecosystem. Microbes are important to human being as they aid in digesting the food, act as a decomposer and without them, there would be a lot less of oxygen to breathe. Around 3.5 billion years ago, microbes have already been living on this earth where there is just ocean. Studies of microbes help us understand the past and the future of human and the planet. Microbes can be divided into six main types; Archaea, Bacteria, Fungi, Protista, Viruses, and Microbial Mergers.
Fungi are multi-cellular organisms which are under the Kingdom Fungi and there are approximately 70,000 types of fungi. Fungi are similar to plant in term of their cell structure and both of them are immobile. However, fungi do not perform photosynthesis hence they need to feed on other organisms. Thus they are more related to animals than plants. Fungi are further classified into Chytridiomycota (Chytrids), Zygomycota , Ascomycota and Basidiomycota by the shape and structure of sporangia. Fungi are useful in several ways; in the production of vitamins and antibiotics, fermentation of cheese and alcohol and decomposition of organic matter which lead to renewal of

The fermenter is a large cylindrical vessel that made up of stainless steel because stainless steel does not stain and rust and it is able to withstand the heat during fermentation. Before fermentation start, the vessel must be sterilised. A uniform distribution of sources and heat needed to be maintained during the process by stirring the liquid medium constantly using the stirrer paddle. Oxygen required for the growth of P.chrysogenum is obtained from the sterile air that is being pumped into the fermenter. Sterile air is necessary to prevent other microorganism from getting into the
Jennifer Ackerman's main focus in her article The Ultimate Social Network, is that of the functions concerning bacteria within humans. Although scientists have had presumptions about humans being proficient in governing their body’s innermost structure, they soon come to recognize the sophistication of our inner space which holds an extensive plethora of bacteria and other microorganisms that lie within each and every one of us. Moreover, scientists' new and emerging view of how the human body operates, and the cause of increasing present-day diseases (i.e. obesity and different autoimmune disorders) are uncovered by analyzing effects of certain microbe species in our bodies. By italicizing on points such as the above, in conjunction with bacteria's genetic variations, and modern computing technology, the author proves that scientists are quickly progressing with the characterization the most prevalent species of microbes, which, in her opinion, is definitely paying off.
The first topic to be discussed in this paper is a description of Hydnum repandum, which was until recently referred to as Dentinum repandum. The description of the fungi will start with the appearance of H. repandum, and will be followed by the life cycle of the noted species.
The purpose of this investigation is to test the effects of multiple sugar substances on the respiration of yeast. Most people think of yeast when they think of what makes bread rise, cheese, alcoholic beverages, or other food products. Another type of yeast can also cause yeast infections, an infection of the skin. Yeasts (Saccharomyces) are tiny, microscopic organisms with a thin membrane and are usually oval or circular-shaped. They are a type of single-celled fungi of the class Ascomycetes, capable of processing sugar into alcohol and carbon dioxide (CO2 ) ; this process is known as fermentation. Fermentation and the products are the main focus points for this experiment being that cellular respiration of yeasts happens via the process of fermentation, which creates by-products of alcohol and CO2. The level of CO2 produced by the yeasts will show how effective each sugar substance is in providing cellular energy for the yeasts.
These germs, or organisms, are often living in or on our bodies. Most of the time they are harmless, and sometimes they are helpful.2 These organisms are often called microorganisms because they are so small they can only be seen through a microscope. There are millions of microorganisms living in your body that help with body functions. The problem is when a microorganism that can cause disease enters your body and starts to multiply. These unwanted microorganisms are called pathogens. Pathogens can be bacteria, viruses, fungi, protozoans and insects or animals.3
Sordaria fimicola belongs to the kingdom of fungi and is part of the phylum Ascosmycota. This fungus habitat is in the feces of herbivores. As many fungi Sordaria have one life cycles which is haploid/ diploid. It is commonly exits as a haploid organism, but when the mycelium from two individuals meets, the result is a diploid zygote. This diploid zygote which undergoes meiosis forms eight haploid ascospores . The ability of Sordaria to make 8 haploid ascospores is what makes it unique and important for the laboratory exercise done in lab.
...standing the nature of relationship between the residing microbes inside human cells and about their function is very important to put an end to this war and to live in peace with the natural organisms that are benefitting human body and their survival has become our primary importance.
Microorganism is a living thing that cannot be seen by naked eye and is so small in size. Microorganism usually can be seen through microscope because microscope have the ability to see small thing using various magnification. The examples of microorganism are bacteria, fungi, protozoa, algae and virus. Among all of the microorganisms, bacteria have the greatest advantages in preserving food and beverages. Bacteria are generally harmless but can produce enzymes that can alter the structure the food. In extreme cases, bacteria can secrete toxic substances that can cause the food to spoil.
In the kingdom of Fungi, is a collection of different organic multicellulary eukaryotic organisms. Fuguses are unique from any other life form. They grow in the wild yet they are not plants. They also breakdown and digest animals and plants alike, but they are not animals. Fungi are made up of chitin, a derivative of glucose that is also found in cephalopods, arthopods and crustaceans alike. Similiar to cellulose which is a what plants' cell walls are comprised of, Chitin is a tough material that gives the Fungi its structure.
This lab has two sections. The first section deals with fermentation. The purpose of the fermentation lab is to alter 5 different independent variables (temperature, acid ph, alkali ph, enzyme concentration, and substrate concentration), to learn about their effects on the ongoing process of fermentation.
Yeast Yeast are a tiny form of fungi or plant-like microorganism (visible only under a microscope) that exist in or on all living matter i.e. water, soil, plants, air, etc. A common example of a yeast is the bloom we can observe on grapes. As a living organism yeast needs sugars, water and warmth to stay alive. In addition, albumen or nitrogenous material are also necessary for yeast to thrive.
Microbes are microscopic life forms, usually too small to be seen by the naked eye. Although many microbes are single-celled, there are also numerous multi-cellular organisms. The human body has 10-100 trillion microbes living on it, making it one giant super-organism. Since the first link between microbes and diseases was made, people have been advised to wash their hands. Scientists, however, have recently started to investigate more closely how the microbes that call the human body home affect our health. While some microbes cause disease, others are more beneficial, working with our bodies in many subtle ways.
The term “microbiology” refers to the branch of study that deals with microorganisms. Microbiology is extremely important in today’s time for the crucial information that the study provides. Human’s have had a long and cruel history of disease and sickness, for example the bubonic plague, but microbiology gives scientists the ability to observe, study, and prevent sickness like the bubonic plague to ever happen again. At the center of microbiology lies the bacterial cell, one that differs from those of a plant or animal because it lacks a nucleus and membrane-bound organelles which, in turn are traded for pili, flagella, and in some cases a cell capsule. Bacteria that are capable of causing illness or disease are called pathogens, pathogens work by releasing toxins in the body or directly damaging the host’s cells. An article by Lise Wilkinson explains that the earliest categorizations of bacterial cells first occurred in the late eighteen-hundreds to the early nineteen-hundreds by scientists (at the time) O. Muller and C. Ehrenburg (Wilkinson, 2004). The observation and identification of unknown bacteria that emerge is crucial because these new bacteria might be pathogenic and cause illness so it is very important that the bacteria is identified as soon as possible in order to either prevent the upcoming illness or treat it. While the common person is unable to identify if they are carrying bacteria (which is very likely), specialized tests that are ran in a lab can identify different types of bacteria and can even help
There were five test solutions used in this experiment, water being the control, which were mixed with a yeast solution to cause fermentation. A 1ml pipetman was used to measure 1 ml of each of the test solutions and placed them in separated test tubes. The 1 ml pipetman was then used to take 1ml of the yeast solution, and placed 1ml of yeast into the five test tubes all containing 1 ml of the test solutions. A 1ml graduated pipette was placed separately in each of the test tubes and extracted 1ml of the solutions into it. Once the mixture was in the pipette, someone from the group placed a piece of parafilm securely on the open end of the pipette and upon completion removed the top part of the graduated pipette.
It is a single-celled organism that is not visible to the human eye, which means it can only be seen with a microscope. Bacteria are classified as Prokaryotes. They make their own food from the sunlight and can absorb food from the materials that they live on.
Microbes are major key components in both are homes and industrial food preparation. There are number of lactic acid which is a form of bacteria which is a large group of beneficial bacteria used in certain foods while they are getting prepared such as yogurt, cheese, sour cream, butter milk and other type of fermented milk products. Things such as vinegars are produced by bacterial acetic acid fermentation. Yeast is also major use in the making of beer and wine and also for the leaving of breads. This also involves fermentations to convert corn and other vegetable carbohydrates to also make beer, wine or gasohol but also bacteria is the agents of are other foods. Other fermented foods will include things such as soy sauce, olives and cocoa. (Microbes and human life, 2013) Single cell proteins are known as dried cells of microbes which are used in protein supplement shacks. They are also called “novel food” and “minifood”. The production of this requires micro-organisms which then serve as the protein source and then the substrate which is biomass which they grow on them. There are a number of both these sources that we are able to use for the production of single cell protein (SCP). The micro-organisms used belong to the following groups of Algae, Fungi and bacteria.
