浅谈微生物与人类的关系摘要:我们应该时刻意识到,在我们的周围和机体内都有其他生命体与我们共存。虽然人类与微生物的斗争会无止境地持续下去,但只要我们充分认识到我们所处的环境,认识到生态平衡对人类的好处,不要为了发展而牺牲环境,而坚持可持续发展战略,那么,人类就能够在这微生物的世界里更好地生存下去。关键字:微生物、人类,祸、福在说明微生物与人类之前,我们首先明确一下什么是微生物。不了解何为微生物又从何谈微生物与我们人类的关系呢?微生物主要是由一群肉眼看不见的单细胞生物所构成的,其种类之繁多,数目之庞大,超乎我们的相像。目前,微生物大致分类为细菌、真菌(包含酵母菌和微菌)、藻类和俗称为寄生虫的原虫和蠕虫。病毒是一种只能在活的生物细胞中复制的简单有机体,严格说来并不能视为一种生物,不过,也被归属于微生物。我们生活中的世界,其实是到处布满微生物的世界,从远古时期起人类就和微生物在地球上共处,人类在适应了微生物的同时,又不断遭遇微生物所引起的各种疫病,因此人类与微生物之间就了战争。1929年,英国细菌学家弗莱明,在研究培养葡萄球菌时,偶然发现了青霉素,这是人类历史上第一个抗菌素类药物的诞生。青霉素能抑制病菌细胞壁的形成,使菌体的新陈代谢失调,达到抑菌和杀菌的效用。之后又出现了很多抗菌素类药物,如头孢霉素、链霉素、氯霉素、四环素、卡那霉素、庆大霉素、红霉素等。一时间,人们就觉得在人类与微生物的斗争中,人类已经领先了,因为如结核菌、细菌性肺炎、败血症、梅毒、淋病和其他细菌性传染病慢慢被征服了。但是,正是由于这些抗菌素类药物有抑菌和杀菌的效用,人们大多数认为,不管患了什么病,总是认为多吃点抗菌素药物好,这就导致了以下问题:在多数情况下,抗菌素的作用只是抑制或削弱病原菌的活动,人最终还得靠机体本身来彻底战胜病原菌。长期使用某种抗菌素,不但起不到应有的作用,相反,还会使病原菌产生"抗药性"变异品种,从而使抗菌素失去它特有的效用。细菌的确很聪明的,一个细菌可在24小时内留下约l60多万个后代,然后成群地更有效地带着抗药性来危害人类。因此,人类和细菌这场无宵烟的战争又开始了,一场领先者不断变化的比赛就这样持续下去。正因为细菌有这种抗药性,科学家们正在研究各种策略。例如,使抗药性的细菌产生带有影响其生存能力的基因,使它更难忍受温度和酸度,使有抗药性的细菌在与同类细菌的竞争中,总处于劣势,这样就可以有效地抑制抗药性细菌的蔓延。即使这样,与微生物的斗争中,人类并不能说完全领先,因为到目前为止,有些疾病依然严重威胁着人类,如艾滋病,还有一些一度被控制的传染病又开始死灰复燃。为了防除这些疾病,全世界虽然已经花费了成千上万的美圆,但这些疾病的罪魁祸首却仍然没有被征服,甚至艾滋病还在每年呈指数增长。这不能不引起人们的高度重视。鼠疫,艾滋病(AIDS),癌症,肺结核、虐疾、霍乱“卷土重来”,埃博拉病毒,疯牛病,还有近一段时间又出现了引起人们恐慌的新疾病SARS,禽流感等都是由一些极少部分的微生物所致,那鼠疫来说吧,1347年的一场由鼠疫杆菌(Yersiniapestis)引起的瘟疫几乎摧毁了整个欧洲,有1/3的人(约2500万人)死于这场灾难,在此后的80年间,这种疾病一再肆虐,实际上消灭了大约75%的欧洲人口,一些历史学家认为这场灾难甚至改变了欧洲文化。我国在解放前也曾多次流行鼠疫,死亡率极高。而且还证实,这些病毒还在变异,这就更加增加了对这些疾病研究的困难。而这些疾病的出现,又是跟人们的行为有关,由于发展的需要,人们对环境进行破坏,造成生态的不平衡,生态环境越来越严重,造成病毒能够接触到人们的机会大大增加,而且加快了它们变异的能力。这些无不是人类自身所种的恶果。但这些祸只是由一极少部分的微生物所致,只有这一少数微生物也是人类的敌人。但并不是说一切的微生物对人类都有危害的,如果是这样,人类或许早就灭亡了,因为上面已经讲了,人类是生活在微生物的世界。那现在就谈谈微生物对人类有好处的一面。微生物无处不在,我们无时不生活在“微生物的海洋”中。细菌数亿/g土壤,土壤中的细菌总重量估计为:10034×1012吨;每张纸币带细菌:900万个人体体表及体内存在大量的微生物:皮肤表面:平均10万个细菌/平方厘米口腔:细菌种类超过500种肠道:微生物总量达100万亿粪便干重的1/3是细菌,每克粪便的细菌总数为:1000亿个;每个喷嚏的飞沫含4500-150000个细菌。时时刻刻与微生物“共舞”是祸?是福?微生物既是人类的敌人,更是人类的朋友!微生物在许多重要产品中所起的不可替代的作用,例如:面包、奶酪、啤酒、抗生素、疫苗、维生素、酶等重要产品的生产体内的正常菌群是人及动物健康的基本保证;帮助消化、提供必需的营养物质、组成生理屏障是人类生存环境中必不可少的成员,有了它们才使得地球上的物质进行循环因为这样,现在有不少的国家正投资把优先发展微生物经济作为发展生物产业的“火车头”,这可是内有乾坤的。发展微生物经济可以充分发挥比较优势,投入少、产出多、见效快、应用广,可以把其他生物产业带动起来,催生大批高新产业,形成巨大的技术经济优势,占领世界生物领域的制高点。具体地用微生物经济带动生物产业,也需要贯彻“有所为、有所不为”的方针,集中力量攻破难关,并与国内外大市场密切结合,利用强大的需求拉动产业的兴起和扩张,使得自主创新与加快转化形成互动机制。1、大力推广已经成熟的微生物技术,尽快形成单独产业,如抗生素、各种人畜疫苗、生物药品、生物农药、生物肥料等应当大力扶持,以优化质量为主线,提高核心竞争力,迅速占领市场、引导市场。2、组织技术集成,使用微生物技术成为重要环节,同发展循环经济的大趋势结合起来。循环经济的一个重要支柱,就是微生物技术。如果在循环经济中的微生物技术有重大突破,那就会带出一批新型绿色产业。较低层次的有把作物秸秆制成沼气、残渣再制成肥料;污物、污水处理中制取再生用水和其他有用物质,更能保护环境。其高端层次,则可获得新的资源和产品,进一步开拓防治微生物污染的领域。3、开展技术创新,利用微生物研究和开发新的生物技术,取得技术突破,获得自主知识产权,打破国外对某些关键性产业的垄断。特别是同中医中药结合,对预防医治人类的疑难病症如癌症、艾滋病、恶性传染病有所突破,就会形成产业。生物能源也应当作为一个重点,集中力量加以攻关。4、在支持性软硬环境方面,应考虑多培养一些应用微生物技术人才,充实微生物研究机构,广泛开展多种形式的产学研结合,国家、社会和企业给予的投入,鼓励发展应用微生物的研发企业。微生物对人类的好处,除了制造食物和生产有用的物质外,环境中的微生物,其实是地球上所有生物所构成的食物链中极重要的一环。若不是微生物所扮演的分解者,忠心地把死亡的生物体不断分解成活生物体成长所需的营养物质,地球上的生物很快就会面临食物短缺而停止繁衍。此外,人类所制造的垃圾和各类毒性物质对环境造成的污染,如果不是靠著微生物的分解,对人类的危害将不只是现今的千百倍而已。人类既然生活在微生物的世界里,那么一些和我们紧密生活在一起的微生物通常对人体无害,甚至可以帮助我们消化食物和产生人体所需的物质,如维生素等。更重要的是,当有致病性微生物入侵的时候,人体往往还得靠这些共生菌一起将它们驱逐出去。只是当人体的免疫力因先天或后天的种种因素而变差时,有些共生菌就会立刻翻脸,露出狰狞的面目,进一步侵入宿主体内的组织和器官,造成致命的感染。因此,保持身体健康有一部分也意味着维持人体和共生菌之间的微妙平衡,而达到一种互利的关系。我们应该时刻意识到,在我们的周围和机体内都有其他生命体与我们共存。虽然人类与微生物的斗争会无止境地持续下去,但只要我们充分认识到我们所处的环境,认识到生态平衡对人类的好处,不要为了发展而牺牲环境,而坚持可持续发展战略,那么,人类就能够在这微生物的世界里更好地生存下去

你这是写教育教学类的论文还是只是说要写生物类的论文呀~这样~生物类的论文 你可以去看下(生物过程、计算生物学、微生物前沿)这样的期刊~教育教学的话~你可以去看下(教育进展、创新教育研究)这样的吧

答案是:B。B项是错误的,田鼠的摄食量减去粪便量即为同化量。D项是正确的,田鼠的同化量是7乘以10的9次方,下一营养级最多得到它20%的能量,也就是40乘以10的9次方。
