Please insert your professor’s name here Please insert course number here Introduction Kinesins are proteins which serve as molecular motors for the directional transport of various cargos (Hirokawa et al. 10: 682-696). They perform this important function using different mechanisms to recognize, bind, determine the direction of transport and unload the cargos with an energy efficiency which can exceed 50%, thereby equipping them to play important roles intracellularly in the transport of organelles and vesicles, in biosensing as well as in the development of other bioengineering solutions (Agarwal 11; Hirokawa and Takemura 301: 50–9; Hirokawa et al. ...

Organism # 6

Molecular Biosciences 101 Section # Purpose Materials and Methods Gram Staining: Three circles were marked at the bottom of a clean glass slide and they were labeled as gram(+), gram(-) and unknown respectively. The three labeled circles were then inoculated with microorganism 6 using an inoculating loop. The bacterial smears were then air dried and heat fixed over a gentle flame. The slide was then flooded with primary stain, crystal violet for a minute by placing it on a staining rack. Excess crystal violet was washed off with a gentle stream of water. Thereafter, gram iodine was added and ...

Tissue and Cellular Organization

The circle of life on the earth is very complicated, though sometimes it seems to be rather easy. People see plants, insects, various fluids, surface and soil, but they often do not think of all the complexity of the constitution of bodies that fill up the world. In other words, everything consists of cells and tissues, and in order to understand the essence of every matter it is important to investigate their structure. There are some organisms, such as bacteria, that are unicellular or they are made up of only a “single cell” (Science Daily, 2014). These one-celled organisms ...

(City, State) Lactic acid fermentation refers to a biological process where sugars such as fructose, glucose, and sucrose undergo conversion to form cellular energy lactic acid. The process is an anaerobic kind of fermentation reaction and takes place in a number of bacteria as well as in animal cells like the muscle cells (Campbell & Reece, 2005). The application of lactic acid fermentation is broad especially in the food industry (Tempeh, 2008). Some of the bacteria that are involved in the production of lactic acid include pediococcus cerevisiae, leuconostoc mesenteroides, bifidobacterium bifidus, and streptococcus lactis (Tempeh, 2008). The process is also ...

Introduction

Bacillus Subtilis are the organisms that are aerobic, Gram Positive, spore-forming belonging to the Bacillus genus. The organisms are together with other species that are closely related play a crucial role in disease, food poisoning as well as food spoilage. Lack of methods that are standardized for the identification of the organisms whether coming from the food or environment has made the tests to be difficult. Use of morphological as well as physiological tests have offered the best ways to identify organisms in the laboratory although there are inconsistent and lack of reliance in these methods. Identification of an ...

Abstract

In this essay, a description is done of the Bacteria species Lactobacillus casei and Clostridium botulinum. Their common ground and similarities are presented, being a part of the Low G+C Bacteria, or Firmicutes: Gram-Positive, rod-shaped and fermenters. Additionally, it is also discussed what are their contrasting traits, that keep them distinguished, together with what are the factors used for the various strains’ differentiation, within each species. Keywords: Lactobacillus casei, Clostridium botulinum, characteristics, similarities, differences, phenotype, structure, phylogenetics.

Low G+C Bacteria – Firmicutes The Bacteria regarded for this essay are part of the Low G+C Bacteria, or Firmicutes. ...

Abstract

In this essay, a description of a non-pathogenic and of a pathogenic microorganism is made. As microbiology aims the study of the microscopic organism that inhabit the ecosystems, the understanding of what are the species present in the biosphere, what are the condition in which they live, what are their metabolic processes and products, and of how can these influence, positively and/or negatively other living forms, including humans, it is essential to study them to know how their caused illnesses be prevented, treated and, furthermore, how can possibly help the health welfare. As examples, the Lactobacillus casei and Clostridium botulinum species of ...

Differences and similarities in the structure of salmonella enterica and lactococcus lactis. The structural makeup of L.lactis makes it compatible with both aerobic and anaerobic reactions which makes it an important microbe for food production. It is a non-pathogenic bacterium with peptidoglycan component in their cell wall. They have cocci shape unlike salmonella enterica that is a rod shaped bacteria. The cocci of these bacteria come in pairs or short chains. The bacteria size is smaller than that of S. enterica. The size is 0.5-1.5 micrometer in length. The Lactococcus lactis is also non motile because of the absence of ...

Pathogenic and Non-pathogenic Organisms

Salmonella enterica is a gram-negative rod, which flagellated. It is a member of the enteriobacteriaceae family and it has six subspecies. The bacteria usually reside in poikilothermic animals (PHAC, 2010). The bacteria has various serotypes which are characterized by surface antigens it includes the H antigen which is a flagellar antigen, the O antigen which is the Oligosaccharide antigen and the Vi antigen which is the polysaccharide antigen. Salmonella enterica is a facultative anaerobic organism. it is a motile, non-sporulating rod. the organism is a glucose and mannose fermenter. it does not produce gas and does not ferment lactose or sucrose. Most salmonellae produce Hydrogen ...

Introduction

Cilia are ancient and evolutionarily conserved organelles which are found on cell surface. This organelle project from those cell surfaces to provide multifunctional biological roles in the organism. An important role that cilia has been known to perform for cells are the locomotion, sensation and reproduction. The implication of the defect in the cilia is that the cell that tend to depend on the organelles for proper performance will be limited in it role. There are many diseases that have been found to be associated with cilia defects. Since cilia occurred as important organelles of many cells, majority of ...

Introduction:

The bacterial negative gram bacilli group Enterobacterriaceae have both motile and non-mitole relationships with peritrichouse flagella. Both types of bacteria, however, have the ability to fermet glucose and get nitrite from nitrates, as well as produce gas. They are a common find in greenhouses, and there are hundreds of species of this microorganism, including Proteus, Escherichia coli, Klebsiella, Salmonella Enterobacter, pneomoniae, etc. The pathogenic types of this bacteria have the ability to bring about diseases in animals and humans.

In this test, two varying types of Enterobacteriaceae will be identified (Klebsiella pneumonia and Escherichia coli. This will be accomplished ...
