CHAPTER I INTRODUCTION 1.1 Background Food is one of human sources of calorie‚ protein‚ fats‚ and nutrition. Yet‚ because of the highly nutritious content‚ food is susceptible to growth of microorganisms. By the presence of microorganisms in food‚ the food is more likely to have shorter shelf life. Thus‚ mostly it is resolved by the addition of antimicrobial substances to food‚ such as condiments and preservatives. Condiments and preservatives could inhibit the growth of microorganisms

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention

The two amylases that are used in the experiment is Aspergillus oryzae and Bacillus licheniformis. B. lichenformis is classified as bacteria that can be seen in soil‚ and is usually transported through a bird’s feathers or plumage. A. oryzae is a type of mold‚ or fungi‚ that is utilized for Asian food production‚ which could include the fermentation of soybeans. The student is required to discover the optimal temperatures for both‚ Aspergillus oryzae (Fungal) and Bacillus licheniformis (bacteria)

Rennet (pron.: /ˈrɛnɨt/) is a complex of enzymes produced in any mammalian stomach‚ and is often used in the production of cheese. Rennet contains many enzymes‚ including a proteolytic enzyme (protease) that coagulates the milk‚ causing it to separate into solids (curds) and liquid (whey). They are also very important in the stomach of young mammals as they digest their mothers ’ milk. The active enzyme in rennet is called chymosin or rennin (EC 3.4.23.4) but there are also other important enzymes

studied. The findings of the chemical study of essential oil of L. camara leaves revealed the presence of a high amount of sesquiterpenes and this oil remarkably inhibited the growth of most tested bacteria and fungi; Pseudomonas aeruginosa‚ Aspergillus niger‚ Fusarium solani and Candida albicans appearing as the most sensitive (Sousa et al.‚ 2012). Considerable research‚ such as this one‚ has focused primarily on the antibacterial properties the essential oil of the Lantana camara has. This research

The allergy testing has shown significant atopy to horses‚ cats‚ dust mite‚ rye grass‚ couch grass and Aspergillus. The obvious concern her is her ongoing exposure to horses and given that she does also have allergic symptoms around her guinea pigs‚ they are likely to be contributing as well. They do have a dog around‚ a Cavoodle‚ but she has no obvious allergies
