Introduction

Fermentation process refers to the conversion of sugars such as glucose to alcohol, carbon dioxide and energy in the form of ATP (Kale and Gokhale). Fermentation occurs in the absence of oxygen and converts substrates such as glucose into products such as acetate or lactic acid. During fermentation, there is no oxidation phosphorylation and thus the amount of ATP that is produced is low (Pigage, Neilsen and Greeder). One specific example of fermentation is lactic acid fermentation, which is the simplest form of fermentation. In the presence of oxygen in the cells, most organisms bypass fermentation to undergo cellular ...

Introduction

Environment incubator can be defined as a modified biological environment to suit a certain experiment. The environment may be modified to provide certain condition necessary for a particular biological experiment. Microbes as microscopic organisms that can either respire aerobically or anaerobically. For instance, yeast is an anaerobe that respires anaerobically. Yeast enzyme is used in the fermentation process because they convert grape sugar into ethyl alcohol. Yeasts are eukaryotic micro organism which belongs to the kingdom fungi and which respires anaerobically. Yeast will be used in this experiment. The main purpose of this experiment will be to determine the factors that may ...

Introduction

All cells carry out cellular respiration in order to meet their energy requirements and to form metabolic intermediates that can be used to form secondary products. Amongst those products formed as a consequence of cellular respiration, are ATP and CO2. The formation of ATP in the cells occurs through the use of organic molecules available in the form of food (Lehninger, Nelson, & Cox, 2008). When oxygen is not available, ATP formation goes through a fermentation process, usually, referred to as alcoholic fermentation. The process utilizes a number of different sugars as the starting material. These sugars include fructose, glucose, and sucrose. The ...

Introduction

Baker's yeast is the ordinary term known of certain generic classes of yeast normally utilized as a baking agent in bread and bakery commodities production, wherein it translates the fermentable glucose and sucrose otherwise found in dough into two products that are carbon dioxide and ethanol. Scientifically, this yeast is categorized under species Saccharomyces cerevisiae (Sonnleitner, 2006). This is the same species frequently employed in the fermentation of alcohol hence the tag brewer's yeast is also accorded to it. In this experiment, we attempted to produce yeast through the process of fermentation (Kristiansen, 2004). The fermentation process is powerfully aimed ...

Abstract

Transformation remains, and hugely significant tool in extending the borders of life sciences and medicine. It can be referred as fixing intracellular DNA into a bacteria or organism through the vector, thus transforming it. This paper uses plasmid pUC18, self-reproducing circular/spherical strands of genes that may be modified. After the bacteria absorb the vector, some proteins not usually synthesized will occur. In this study, a system has been developed to monitor the transmittance of different DNA (genes) from a genetically transformed strain of Saccharomyces cerevisiae to E. coli. This mechanism is centered on yeast strains that contain several integrated ...

Abstract

Water is an important chemical owing to its various uses by living things. Most chemical reactions within the bodied of living things require water in order to occur. It is purported that life evolved from water some 3.8 billion year ago following the organization of inorganic and organic molecule to form as prokaryotic cells. Besides, the well being of a cell is overly dependent of the balance between the water and the dissolved substances in the water. In this regards, the cell can permit water molecules to move in and out of the cell; the process in called Osmosis.

Yeast, Epithelial and Dental plaque

Compare your observations from the four activities of fresh wet mount, direct staining using crystal violet, and indirect staining using both Congo Red and crystal violet.
Wet mount of S. cerevisiae under magnification of X10 and X40, revealed the cells as being independent, with oval shapes. All the cells in wet mount, had same shape appearance, with borders that could not be clearly distinct. However, in wet mount, it was not easy to determine epithelial cells shape. In the direct staining, cells shapes could be determined since cells had a violet color. This made the cells to be visible ...

Introduction

Elodea canadensis is a perennial hydrophyte, which is native to the majority of North America and was first recorded in about 1836 from the British Isles (Hackney, 1992). Young plants at first begin with a seedling stem and roots grow in mud at the underneath of water. More adventitious roots arise at intervals along the stem. The leaves are translucent, bright green, oblong, 1-4 mm broad and 6-17 mm long, borne in whorls of three round the stem (Rose, 2006). It lives completely submerged.

Article Review

In this paper, I review the article Fundamentals of Beer and Hop Chemistry, authored by Keukeliere, D. (2010).
In his article, Keukeliere (2010) begins by indicating that beer, an aqueous fermented drink, is based on starch, but flavored by hops. Keukelier (2010) notes that, barley, and most specifically barley malt, is the main body of beer. In order to produce one liter of beer, a few hundred grams of barley malt are needed. However, Keukeliere (2010) indicates that in the absence of barley malt, starch-rich adjuncts such as wheat, corn or rice can be used.
Keukeliere (2010) notifies ...

Purpose

Materials and Methods
Gram Stain: the test was done to differentiate Gram-positive from Gram-negative organisms. A drop of the unknown 300 was suspended on a slide and the culture spread to an oven thin film. The culture was air dried and fixed over a gentle flame. Crystal violet stain was added over the culture and allowed to stand for 60 seconds. The stain was poured off and rinsed gently. Iodine solution was added on the smear, allowed to stand for 60 seconds and the stain poured off. The slide was rinsed with running water, and a few drops of decolorizer solution ...

In assessing the impact of microbes in the New South Wales (NSW) health system, it was discovered after laboratory testing evaluating Part A and B categories different types of colonies were discovered, for laboratory 1 evaluations. In laboratory 11specimens used in this experiment were blood, urine, cerebrospinal fluid; sputum, swabs from and
