当前,世界人口与粮食的矛盾越来越突出。据美国《科学》杂志的统计,目前,全球有5亿人因食品不足而患营养不良症。为缓解这一矛盾,科学家把目光移向了人工食品,而石油食品——从石油中提取蛋白质被认为是可行性最强的一项技术。 那么,石油是怎样变成食品的呢?众所周知,在自然界中有许多微生物。科学家发现,有些微生物是以“吃”石油为生的,这些微生物把正构烷烃和甲烷作为食物而“生产”出蛋白质,科学家就对这些微生物进行筛选,培育,繁殖,然后将它们接种到正构烷烃的液体石腊上,并提供其生长繁殖的必要条件,比如氧气、水、温度和酸碱度等。这样,这些微生物在消化、分解石油之后,繁殖出无数的后代,待它们长成后,采用先进的 At present, the contradiction between the world’s population and food has become increasingly prominent. According to the statistics of the United States “Science” magazine, at present, 500 million people around the world suffer from malnutrition due to lack of food. To alleviate this contradiction, scientists have turned their attention to artificial foods, and oil foods—the extraction of protein from oil—are considered to be the most viable technologies. So, how does oil become a food? As we all know, there are many microorganisms in nature. Scientists have discovered that some microbes eat “eating” oil. These microbes use “n-alkanes” and methane as food to “produce” proteins. Scientists screen, incubate, breed, and inoculate these microbes. The paraffin liquid paraffin and provide the necessary conditions for its growth and reproduction, such as oxygen, water, temperature and pH. In this way, after the microorganisms digested and decomposed petroleum, they produced numerous offspring, and when they grew, they used advanced technologies.
