I. significance and purpose.
Microbiology is the study of microbe and its life activities. Microorganism has many characteristics such as various kinds, small size, many metabolic types, high metabolic intensity, rapid growth and reproduction speed, and easy to mutate. It is widely distributed in air, water, soil, human body and animal and plant body, independent or parasitic life. Most microbes can be beneficial to humans and animals and plants, in particular, it has close relation with human life, to industrial and agricultural production and human living environment and health has a great impact. Microorganism in high school teaching of middle school with the new curriculum reform, the space also increased, especially microbiological laboratory cultivation experiment is ordinary high school curriculum standard experiment textbook biological choice of a topic. Microbiology experiments are not only comprehensive and operable, but also require students to have strong aseptic operation skills and biosafety awareness. It is of great significance to cultivate students theory, practical ability, analytical problem-solving ability and scientific thinking.
Ii. Functions and requirements.
Microbiology laboratory of the main equipment are: fermentation tank and high pressure sterilization pot, super clean workbench, thermostatic incubator, constant temperature and humidity incubator, electrothermal blowing, pipetting device, Olympus microscope, refrigerator, the far-infrared temperature oscillator, fast drying box and other modern high-tech laboratory equipment. The laboratory can carry out experiments on microbial culture, production and separation of microbial metabolites, microbial index detection of food and drinking water, and screening of microorganisms. It is necessary to complete the teaching experiment of teaching materials well, and modern instrument configuration can satisfy students interest inquiry activities.
The microbiology laboratory consists of six parts: preparation room, washing room, sterilizing room, sterile room, constant temperature medium and ordinary laboratory. The common characteristic of these rooms is the texture of floor and wall is smooth and hard, the display of instrument and equipment is concise, easy to clean.
