就生命的化学本质而言,生物的任何结构与成份都是由化学元素结织而成的。依据生物体内元素含量的多寡,可分为巨量元素和微量元素。微量元素与生命活动的关系日益受到重视。近年来,很多研究表明,微量元素与微生物的生命活动关系密切,这为研究微生物的生命规律开拓了新的领域。现将有关的研究概况作如下综述。 In terms of the chemical nature of life, any structure and composition of living things is made of chemical elements. According to the amount of elements in the body, can be divided into a large number of elements and trace elements. The relationship between trace elements and life activities is paid more and more attention. In recent years, many studies have shown that the trace elements are closely related to the life activities of microorganisms, which open up new fields for the study of the life laws of microorganisms. The relevant research overview is summarized below.
