Molds and Yeasts in Microbiology - Essay Example

Molds and Yeast in microbiology al Affiliation: Moulds and yeast are both Eukaryotic, ified in the Fungus kingdom. They have strong aromas and can be considered parasites. For optimal reproduction and growth both molds and yeast require warmth moisture-humidity and low light. However they differ in various ways, for instance, while molds have numerous identical nuclei and develop in the hyphae form of filaments, the yeast contains only one cell (Deák & Farkas, 2013; 54)Yeast reproduce asexually through mitosis (budding) and make anaerobic respiration while the molds reproduce both sexually and asexually through small spores and mainly respire aerobically.

They also differ in colour in that the molds are colourful while yeast is just white and thread. Molds are in most cases live in moist, shadowy or steam-filled parts while yeast can be found in the stomachs of mammals, on fruits, on skin, etc.( Burton & Engelkirk, 2000; 25)In spite of the fungi’s role in causing diseases, they still are beneficial and useful organisms to the human beings and are utilized both commercially and industrially. For example, the use of yeasts in the fermentation process in brewing, bread making and wine making.

Yeasts and other fungi also play a significant part in bio-control agent, food processing, enzyme biotechnology, drug manufacture, as well as research and development.People risk fungal infections when the stability of microorganisms in the vagina, mouth, intestines and other places in the body is interfered with, and results in an overgrowth of fungus. Pathogenic fungi cause human infectious diseases which are classified according to their degree of tissue involvement and means of entry to the host.

(Cowan & Talaro, 2009; 403). Superficial mycoses are restricted to the outmost cover of the skin, the hair, and nails. Some common examples are ringworm, athletes foot, jock itch, and yeast infections. Cutaneous mycoses go deep into the epidermis, and also comprise invasive hair and nail infections. Subcutaneous mycoses infections are localised to the dermis, subcutaneous tissue or adjacent structures such as; muscle and fascia. However, systemic mycoses mainly involve deep infections of the internal organs because primary pathogens that are inherently virulent originate primarily in the lungs, and may spread through to many organ systems (Jucker, 2003; 18).

Pathogenic fungi produce infections that are classified into two: systemic and superficial. Systemic infections involve internal organs. Fungi can transmit a disease to deeper tissue causing septicemia, which are diseases affecting blood and easily spread all through the body. In most cases, it begins in the lungs, but in serious cases may spread to the blood, brain, liver, kidneys, heart, or other parts of the body. Superficial diseases affect the exterior parts of the body, the skin, the hair, and nails.

Fungal diseases cause minor skin diseases. They most often occur in moist areas, such as in the mouth, between the toes, or in the crotch (Kim, 2008; 824)The yeast and bacteria are alike in that they both crop naturally; they are both a variety of microbes and have ribosome to help manufacture protein for the cell. Perhaps the most significant dissimilarity is that Yeasts (fungi) are Eukaryotic cells and bacteria (Monera) are prokaryotic cells. This in essence means is that Yeasts have their DNA enclosed in a nucleus.

Bacteria, however, do not have a nucleus and their DNA is not tight within their cytoplasm.ReferencesBurton, G. R., & Engelkirk, P. G. (2000).Microbiology for the health sciences (6th ed.).
