Ⅰ.microorganism & microbiology


1-1 introduction to microbiology


❍ microbiology(미생물학)


간단히 말해 미생물(microorganism)을 연구목적으로 하는 학문이다.


미생물이라는 생명체를 대상으로 연구하는 생명과학의 한 분야이다.

분류, 생리, 유전에 관한 것을 생물화학, 생물물리학, 면역학, 유전학 분야에서

주로 연구하고 생태학적 분야를 비롯한 응용분야는 유전자공학, 발효공학에서 다룬다.

초기의 미생물학은 사람, 동물, 곡식류의 병원미생물을 주로 다루는 의학, 수의학, 식물병리학에서 시작하여, 식품의 발효와 저장문제를 다루는 식품과학과 함께 발전해 왔다.

그러나 오늘날에는 생명현상을 밝히는 기초학문으로서 분자생물학과 함께 중요한 위치를 차지하며, 유전공학과 항생물질의 생산 또는 에너지와 환경오염의 문제 해결에도 중요한 역할을 하고 있다.
