Experiment Microbio

PART 2 : ASEPTIC TECHNIQUES AND TRANSFER OF CULTURES Objectives: 1) To apply healthful techniques in microbial cultivation 2) To isolate pristine colonisation by streak case method 3) To assign bacteria by several(prenominal) methods INTRODUCTION Microbes exist everywhere and they become the bloodline of contamination towards any(prenominal) effected pure cultures. Pure culture is critical in any laboratory which participates in activities related to scientific explore especially in biotechnology. Pure culture, which is defined as a culture containing one particular species of microbe, give modify scientists to come scientific research and identify the microbe for pillow slip in diagnostic purposes. Therefore, it is all important(p) for any microbiologists to maintain the honesty of cultures, stop from any contaminant. Techniques that can help microbiologists avoid contamination ar referred to as aseptic techniques. These techniques are also crucial in m aintaining safety for other workers and environment. Basically, aseptic techniques work by avoiding contacts in the midst of contaminants and pure cultures. Without aseptic techniques, this would allow other microbes to contaminate the pure culture.

In this experiment, the broth culture leave transfer into liquidity intermediate, cultures from agar medium transfer to semisolid agar medium using stab inoculation and other one is transfer cultures from solid medium to slant agar. We will also establish the pure cultures by streak base method to set out oneness cell of bacteria. resolvent Inoculum sourceTransferred to:Observation(Draw and label),Discussion and conclus ions NA,petri salmon pinkNA,petri dish Br! othBroth nutritive agarStab Nutrient agarSlant headspring 1.Explain how procedures in streak plate method would generate single isolated colonies?
