is directed to determine the effect of pH on growth of microorganisms by varying the pH ranges: pH3‚ pH6‚ pH7‚ pH9; the last part is about effect of oxygen requirement on growth of microbes‚ where the microorganisms grow depending on oxygen demand. Introduction: Microorganisms are classified depending on growth requirements. In this laboratory the microorganisms are divided due to effect of temperature‚ pH and oxygen demand. The microorganisms are divided into three groups depending on temperature

physical methods.and in this experiment we will talk about chemical agent and its affect on bacteria which depends on the concentration ‚type and intensity of agent ‚ the length of exposure to the agent ‚ the number of microorganism present and the material bearing the microorganism . Bacterial growth can be controlled by chemical agents such as: sterilization in which we kill all living organisms. Disinfection‚ decontamination‚ disinfectant‚ antiseptic‚ sanitizer and antibiotic are another chemical

improve the drinking quality of water. There are also ultraviolet systems which do a remarkable job at disinfecting water. Ultraviolet systems can destroy 99.99% of harmful microorganisms in the water very effectively and they do this by using a lamp or bulb which emits UV light which is then used as energy to attack the microorganism in the water and essentially destroy it‚

� Microbiology is the study of microorganisms� Microorganisms‚ roughly‚ are living things that are too small to be seen with the naked eye� Microorganisms cannot be distinguished phylogenetically from �macroorganisms� (see variety of microorganisms‚ below)� Microbiology is more a collection of techniques: aseptic technique‚ pure culture technique‚ microscopic observation of whole organisms‚ etc.� Microbiologists isolate specific‚ culturable microorganisms from wild populations

INTRODUCTION: In this laboratory exercise explore the differences of microorganism and continue our use of specialized media and use some biochemical testing.This report discloses the basic laboratory instruments will be used in each of our practices .It is of great importance to recognize and identify the different instruments and laboratory tools‚ because in this way will we be able to use them properly and also to call them by name and know why.

multiplication of different pathogenic microorganisms in the body-such as fungi‚ bacteria and viruses- the body’s reaction to it and the defense mechanisms it activates to counter these pathogens or the toxins they produce. Infections can range from simple to complex ones that can be fatal or debilitating‚ but because of the continuous researches and studies to protect the human race‚ antibiotics were discovered. Antibiotics inhibit the release of toxins of these microorganisms or simply fight against them
