auxotroph
发音：['??k?t??f]
基础释义：
1. 营养物（如氨基酸、糖等）的缺乏者，不能从环境中获得所需营养物质的生命体。
2. 营养依赖型微生物，不能直接利用环境中的简单有机物，而必须以其他微生物或其它有机物为食。
英语范文：
As an auxotroph, I always need to consume other organisms or organic substances to obtain the necessary nutrients for my survival. Without these nutrients, I would not be able to grow and reproduce. Therefore, I am constantly on the lookout for suitable food sources to ensure my survival.
在英语作文中，auxotroph可以作为名词使用，表示缺乏某种必需营养物质的微生物。同时，它也可以作为形容词使用，表示依赖其他微生物或有机物生存的微生物。在写作中，我们可以根据语境选择合适的词义进行表达。
auxotroph基础释义
Auxotrophs是指那些需要外部营养物质才能生存的生物体。它们通常需要从环境中获取特定的营养物质，如氨基酸、维生素、矿物质等，才能维持生命活动。因此，auxotroph的基础释义就是指那些依赖外部环境才能生存的生物体。
auxotroph的发音
Auxotroph的发音为[???k??t??f]。这个单词的发音相对简单，只需要注意单词中的元音字母和辅音字母的发音即可。
auxotroph英语范文
在我们的生态系统中，auxotrophs扮演着重要的角色。它们是生态平衡的重要组成部分，因为它们需要外部营养物质才能生存和繁殖。然而，随着人类活动的影响，auxotrophs的数量正在减少，这可能会对生态系统造成负面影响。
例如，一些植物和微生物需要特定的矿物质才能生长。如果这些营养物质被过度开采或污染，它们就无法获得足够的营养物质来维持生命活动。这可能会导致它们的数量减少，甚至可能影响到整个生态系统的健康。
因此，我们需要采取措施来保护auxotrophs。我们应该合理利用资源，减少污染，保护环境，以确保它们能够获得足够的营养物质来维持生命活动。只有这样，我们才能保护生态系统的健康和稳定。
总的来说，auxotrophs是我们生态系统的重要组成部分，我们需要关注它们，保护它们，以确保我们共同的地球家园能够持续发展。

Auxotroph
Auxotrophs are organisms that require nutrients that are not present in their natural environment. They must obtain these nutrients through some form of genetic manipulation or other means of artificial supply. Auxotrophs are commonly used in laboratory settings for research purposes, as they allow for the study of genetic and metabolic processes in a controlled environment.
In order to become auxotrophs, organisms undergo genetic manipulation in which certain genes are modified or deleted to render them dependent on specific nutrients. This allows researchers to study the effects of these nutrients on the organism's growth, development, and function. Auxotrophs also provide a means of genetic engineering, as they can be used to create new organisms with desired traits through the introduction of specific genes.
In addition to their use in research, auxotrophs have potential applications in medicine and agriculture. For example, they can be used to create crops that require less fertilizer and water, thereby reducing environmental pollution and conserving resources. Auxotrophs can also be used to create cells and tissues that are more suitable for transplantation into patients, as they do not require the presence of certain antigens that can cause rejection.
Overall, auxotrophs provide a valuable tool for studying genetic and metabolic processes, engineering new organisms, and developing more sustainable agricultural and medical practices. By further understanding auxotrophs and their applications, we can better harness their potential to address some of the world's most pressing challenges.
