ISOLATION OF TRIMYRISTIN FROM NUTMEG ABSTRACT The purpose if the experiment was to extract the Trimyristan from ground nutmeg using extraction‚ distillation and recrystallization procedures. This experiment involves extraction and separation techniques that yield a purified product. The product was extracted and a distillation process was used to remove any remaining solvent. The recrystallization of the sample in turn produced a pure sample‚ which was proven using the known melting

Introduction It is crucial in the field of microbiology to study the morphology‚ biological activity‚ and the behavior of microbes thus the isolation of such microbes from the environment is necessary because it allows scientists to study them in close proximity. Microbial life forms are found everywhere. They are major players in biogeochemical cycling of elements and primary producers in numerous environments. There are also some microbes living inside higher forms of organisms that aid in digestion

MANIPULATION OF BACTERIA INTRODUCTION: In this experiment that we performed‚ there were many methods that were used to help us manipulate and identify the bacteria E.coli on a MacConkey agar plate. The first part of the experiment involved the methods of manipulating‚ identifying and counting the bacteria and the second part was to find out whether the bacteria E.coli was the only type found in the given area by gram staining. E.coli was the chosen bacteria for this type of experiment. It is

Cheese: A Home to Bacteria “Cheese is just a means of controlled spoilage‚” said Steve Jenkins‚ a Master Cheesemonger at Fairway Market. (Cheese) Bacteria‚ or starter cultures‚ control the flavor‚ hardness‚ type‚ and many more aspects of cheese. The two main strands of bacteria involved in cheese making are Lactococcus and Lactobacillus‚ which ferment sugars found in the milk. Humans have learned to manipulate bacteria and the fermentation process to produce different types of cheese such as Swiss

Nowadays mixed marriages have become more and more widespread and common than they were many decades ago. In former time‚ many countries such as Saudi Arabia ‚ Pakistan‚ Egypt and even Germany had strict regulations and restrictions‚ which didn’t allow to get married with a person of another nationality. However‚ these days time has changed and mixed marriages gradually have increased. According to the Associated Press‚ it was estimated 65000 interracial marriages in 1970‚ and then this number has

Techniques for Isolation of Pure Cultures Objective : i. To perform the spread plate and the streak plate inoculation procedure for the separation of the cells of a mixed culture so that discrete colonies can be isolated. ii. To prepare a stock culture of an organism using isolates from the mixed cultures prepared on the agar streak-plate and/or the spread plate. Introduction : In order to be able to adequately study and characterize a certain microorganism‚ microbiologists need to separate

ANALYSIS OF BACTERIA GROWTH Abstract Bacteria can be found everywhere on the earth. Bacteria are single-celled organisms that lack a nucleus‚ mitochondria‚ and chloroplasts and are surrounded by a cell wall containing a peptidoglycan layer. They are defined by their small size and wide range of shapes. In this experiment we separated organisms in a mixed culture to study the colony morphology and physical characteristics and determine which organism was present in higher numbers‚ as determined

Mixed Economic System A mixed economy is an economic system in which both the private sector and state direct the economy‚ reflecting characteristics of both market economies and planned economies. Most mixed economies can be described as market economies with strong regulatory oversight and governmental provision of public goods. Some mixed economies also feature a variety of state-run enterprises. A mixed economic system (also known as a Dual Economy) is just like it sounds (a combination of economic
