2.2 세균을 이용한 제품
주로 이용되는 세균은 Pseudomonas, Bacillus, Agrobacterium 및 방선균인 Streptomyces 등이다. 이들 대부분은 대사산물로서 항생물질을 생산하며 앞서의 곰팡이를 이용한 제품과 마찬가지로 토양 병원균으로부터 작물을 원천적으로 보호하는 기능을 한다.

crystal growth of semiconductors or other covalent nonmolecular solids directly from solution are presently rare. We report the synthesis of crystalline InP from the solution-phase organometallic reaction 1a conducted at low temperatures. Our elucidation of the chemical pathway revealed unexpected factors responsible for InP formation and crystallization, prompting discovery of the solution-liqui
