NTRODUCTION Often in the study of microbiology‚ the need to identify an unknown microbe may arise. This aids in the recognition of which microbes are harmful or pathogenic as well as those that may be beneficial to us in some way. This report will detail how a similar project was performed in order to identify two unknown micobes using the techniques that were learnt during the course of the semester. We embarked on the project with the knowledge that we would have to identify a Gram(+) as well

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

Multiplication of contaminant bacteria in urine and interpretation of delayed culture. Abstract A prospective study of the bacterial populations of non-infected urine was mounted in an attempt to define the length of delay between voiding and analysis during which culture would not give false positive results due to the multiplication of contaminant bacteria present at the time of voiding. The findings suggest that culture of urine within four hours of voiding is likely to give a true indication
