Bacteria cross contaminants - Essay ExampleAfter 24 hours of growth on both MacConkey and r2a plate, small growth was detect in all the samples. Similarly after 48 hours, large colonies were detect on both media for samples ec1 and ec2 but this was relatively higher on ec5 and ec 6.After undertaking Gram staining, it was observed that all the samples on both media had Gram positive bacteria. Catalase test indicated positive results on all the samples. jibe to the result findings, the most probable bacteria identified were all cocci, bacilli, and spirilla. Besides, sample ec5 and ec 6 seems to pass on high levels of cross contamination. These tests capture been explored in the next fragment. Chapter 1 Introduction 1.1 Background By definition, rape contamination is the transfer or physical movement of bacteria that are harmful from one place, psyche or object to another. It is a major factor which contributes to victuals poisoning, and it consists of 4 common sources that inc lude people, puddle surfaces, food and equipment.
