For each genus, the authority, the date of publication, status, systematic position, number of accepted species, distribution, and key references are given. Diagnoses of families and details of orders and higher categories are included for all groups of fungi. In addition, there are biographic notes, information on well-known metabolites and mycotoxins, and concise accounts of almost all pure and applied aspects of the subject (including citations of important literature).All information has been updated as necessary since the publication of the ninth edition in 2001. In addition, the tenth edition has the following new features:A completely new classification of the Kingdom Fungi based on recent multi-gene phylogenetics researchA major revision of the classification of the Basidiomycota and substantial modification of the"basal" groupsFurther integration of anamorphic and teleomorphic genera in the classificationEnhanced distinctions between the true fungi and unrelated groups traditionally studied by mycologistsImproved information on references to publicationsFeaturesFungal Families of the WorldReviews"The Dictionary of Fungi is surely one of the most indispensable of all mycological publications - every student of the fungi should own, or have access to, a copy of the most recent edition." -- Bryce Kendrick, Mycologist , Feb. 2003"This dictionary is an essential reference for all who work with fungi...Teachers and students of mycology, plant pathologists, ecologists, industrial biologists, and others interested in mycology will find this dictionary an interesting and useful reference." -- HortScienceProduct Details640 pages; 5-1/4 x 7-3/4; ISBN13: 978-0-85199-826-8ISBN10: 0-85199-826-7About the Author(s)Edited by P.M.

IntroductionMicrobes are a diverse group of organisms that can be divided into the viruses, unicellular groups (Archaea, Eubacteria, protista, some fungi and some chlorophyta) and a small number of organisms with a simple multicellular structure (the large fungi and chlorophyta).Microbiology: the science (logos) of small (micro) life (bios). The study of living things so small that they cannot be seen with the naked eye.The three-domain system is a biological classification introduced by Carl Woese that divides cellular life forms into archaea, bacteria, and eukaryote domains. In particular, it emphasizes the separation of prokaryotes into two groups, originally called Eubacteria(now Bacteria) and Archaebacteria (now Archaea).Microorganisms were first visualized by Antoni van Leeuwenhoek(1632–1723), a Dutch cloth merchant and an expert lens grinder.The first proof of the involvement of bacteria in disease and the definitive proof of the germ theory of disease came from the German Robert Koch.Koc h’s postulates:1, The microorganism must be present in every instance of the disease and absent from healthy individuals.2, The microorganism must be capable of being isolated and grown in pure culture.3 ,When the microorganism is inoculated into a healthy host, the same disease condition must result.4, The same microorganism must be re-isolated from the experimentally infected host. Chapter oneFungi include yeasts, molds, and mushrooms.Viruses are noncellular organisms; they are intra-cellular parasites of animals, plants, or bacteria. 1, The Prokaryotes can be divided into two kingdoms, Bacteria and Archaea. The classification was first proposed by Woese based on the differences in 16S rRNA sequence.2, Prokaryotic microorganism〔原核微生物〕: It is an single-celled organism which doesn’t have a nuclear membrane outside the cell nucleus and only has the bare DNA called as the nuclear area. 3, Many bacteria are shaped like long rods twisted into spirals or helices; they are called spirilla 〔螺旋菌〕if rigid and spirochetes (螺旋体) when flexible.4, Capsules (荚膜) and slime layers (粘液层) usually are composed of polysaccharides (多糖), but they may be constructed of other materials.5, Gram staining procedure(革兰氏染色的步调)In the first step of the Gram-staining procedure, the smear is stained with the basic dye crystal violet, the primary stain. It is followed by treatment with an iodine solution functioning as a mordant. That is, the iodine increases the interaction between the cell and the dye so that the cell is stained more strongly. The smear is next decolorized by washing with ethanol or acetone. This step generates the differential aspect of the Gram stain; gram-positive bacteria retain the crystal violet, whereas gram-negative bacteria lose their crystal violet and become colorless. Finally, the smear is counterstained with a simple, basic dye different in color from crystal violet. Safranin, the most common counterstain, colors gram-negative bacteria pink to red and leaves gram-positive bacteria dark purple.6, The Mechanism of Gram Staining 〔革兰氏染色的机制〕Although several explanations have been given for the Gramstain reaction results, it seems likelythat the difference between gram-positive and gram-negative bacteria is due to the physical nature of their cell walls. If the cell wall is removed from grampositive bacteria, they become gram negative. The peptidoglycan itself is not stained; instead it seems to act as a permeability barrier preventing loss of crystal violet. During the procedure the bacteria are first stained with crystal violet and next treated with iodine to promote dye retention. When gram-positive bacteria then are decolorized with ethanol, the alcohol is thought to shrink the pores of the thick peptidoglycan. Thus the dye-iodine complex is retained during the short decolorization step and the bacteria remain purple. In contrast, gram-negative peptidoglycan is very thin, not as highly cross-linked, and has larger pores. Alcohol treatment also may extract enough lipid from the gramnegative wall to increase its porosity further. For these reasons, alcohol more readily removes the purple crystal violet-iodine complex from gram-negative bacteria.简而言之，不同细菌的染色差别〔G+或G-〕是由于细胞壁化学成分的差别而引起了物理特性〔脱色能力〕的不同。

天然香精及其鉴定方法介绍
天然香精及其鉴定方法介绍多年来，崇尚自然、回归自然已成为世界性的不可抗拒的潮流。
食品香料与香精的发展也无法逃离这一潮流。
“天然的就是安全”或”天然的至少比人造的更安全“的观念根深蒂固。
但是，从香料化学家角度来看，这是毫无根据的，一种天然香料与一种化学结构和纯度相同的合成香料相比，在毒理学上、营养学上和感官作用上毫无区别。
一、天然香精定义1.1欧盟有机产品中要求欧盟有机标准EC834/2007＆889/2008、规定了天然调味剂（天然香精）才可以添加到有机产品中，在欧共体理事会88/388/EEC中定义了天然食用香料或天然调味剂（人工调味料等同于天然调味料，但是加工调味料和烟熏调味料是不允许的）。
不同于食品色素，包括天然的，天然调味剂在任何情况下都可以使用。
食品色素是不允许食用的，作为肉和蛋壳的印章色素除外。
1.2欧盟香精香料法规88/388/EEC中规定了天然香料的定义，如下：natural flavouring substances in the case of flavouring substances defined in Article 1 (2) (b) (i),Article 1 (2)(b) ‘flavouring substance' means a defined chemical substance with flavouring properties which is obtained:(i) by appropriate physical processes (including distillation and solvent extraction) orenzymatic or microbiological processes from material of vegetable or animal origin either in the raw state or after processing for human consumption by traditional food-preparation processes (including drying, torrefaction and fermentation),从天然原来经物理或发酵方法得到的香料称为天然食品香料。

微生物
Chapter 1 The Main Themes of Microbiology1. Microorganisms, also called microbes, are organisms that require a microscope to be readily observed.Microorganisms(微生物)，也叫microbes，是需要通过显微镜才能容易看见的生命体。
2. In terms of numbers and range of distribution, microbes are the dominant organisms on earth. 就数量和分布范围而言，微生物是地球上的主宰生物。
3. Major groups of microorganisms include bacteria, algae, protozoa, fungi, parasitic worms, and viruses.微生物的主要类群包括：细菌、藻类、原生动物、真菌、寄生虫和病毒。
4. Microbiology involves study in numerous areas involving cell structure, function, genetics, immunology, biochemistry, epidemiology, and ecology.微生物牵涉众多领域的研究，包括细胞结构、功能、遗传学、免疫学、生化、流行病学和生态学。
5.Microorganisms have developed complex interactions with other organisms and the environment.微生物在与其他生命和环境之间发展了复杂的作用机制。
6. Microorganisms are essential to the operation of the earth’s ecosystems, as photosynthesizers, decomposers, and recyclers.作为光合作用者、分解者和循环参与者，微生物在地球的生态系统运作中必不可少。
chapter1-7真菌
1.6真菌Fungi是真核微生物，有明显的真正细胞核，没有叶绿素，不能进行光合作用，是腐生或寄生的。
真菌可分单细胞和多细胞两类。
单细胞真菌呈圆形或卵圆形，称酵母菌(yeast)。
多细胞真菌大多长出菌子，交织成团，称丝状菌(filamentous fungus)，又称霉菌(mold)。
Filamentous fungi Unicellular fungi主要有4个特点：①有边缘清楚的核膜包围着细胞核，而且在一个细胞内有时可以包含多个核，其它真核生物很少出现这种现象；②不含叶绿素，不能进行光合作用，营养方式为异养吸收型，即通过细胞表面自周围环境中吸收可溶性营养物质，不同于植物(光合作用)和动物(吞噬作用)；③以产生大量孢子进行繁殖；④除酵母菌为单细胞外，一般具有发达的菌丝体。
1.6.1酵母菌Yeast在自然界分布很广，主要分布于偏酸性含糖环境中。
如水果、蔬菜、蜜饯的表面和果园土壤中。
酵母菌种类很多，约56属500多种。
酵母菌是人类利用最早的微生物，与人类关系极为密切。
千百年来，酵母菌及其发酵产品大大改善和丰富了人类的生活，如各种酒类生产，面包制造，甘油发酵，饲用、药用及食用单细胞蛋白生产，从酵母菌体提取核酸、麦角甾醇、辅酶 A、细胞色素C、凝血质和维生素等生化药物。
少数酵母菌能引起人或其它动物的疾病，其中最常见者为“白色念珠菌”(白假丝酵母，Cndida albicans)和新型隐球菌(Cryptococ cus neofo rmans)。
它们能引起人体一些表层(皮肤、粘膜或深层各内脏和器官)组织疾病。
如鹅口疮、阴道炎、轻度肺炎和慢性脑膜炎等。
酵母菌的特点：①个体多以单细胞状态存在；②多数出芽生殖，也有裂殖；③能发酵糖类产能；④细胞壁常含甘露聚糖；⑤喜在含糖量较高的偏酸性环境中生长。
(1)形态、大小和结构Morphological Characteristics, Size and Structure Y easts are usually unicellular. Y east cells are larger than most bacteria. 1-5 um in width and 5-30 um or more in length. They are commonly egg-shaped. Y easts have no flagella. 是单细胞真菌（也有多个细胞相互连接成菌丝体的，是因为它在繁殖时子细胞没有脱离母体而与母细胞相连成链状，称为假菌丝，）。

21.1 What Are the Key Features of Plants?
– The organism was bathed in a nutrient-rich solution – It was supported by buoyancy (浮力) and not likely to dry out – Life in water facilitates reproduction
Plants exhibit three characteristic traits:
1. Photosynthesis 2. Multicellular embryos 3. Alternation of generations
Each of these traits occurs in some other kinds of organisms, but only plants combine all three

灰肉红菇与其相似类群子实体下土壤真菌多样性探究祁亮亮1，吴小建1，李俐颖1，莫长明2，郎 宁1，陈振妮11. 广西壮族自治区农业科学院微生物研究所（食用菌研究所），广西南宁 530007；2. 广西作物遗传改良生物技术重点开放实验室，广西南宁 530007摘 要：灰肉红菇是广西等地特色野生食用菌，生于锥属植物林地，但其与相似类群子实体下土壤真菌多样性研究并不系统，土壤真菌功能未见报道。
本研究在广西浦北县同一样地，以灰肉红菇（H ）及其相似类群（玫瑰红菇JH ，毒红菇FH ；白黄乳菇DZ ）子实体下土壤为研究对象，采用高通量测序技术，明确土壤真菌的多样性及群落组成、优势类群及其功能。
结果表明，H 、JH 、FH 、DZ 子实体下土壤真菌均匀度相似，但H 丰富度最高，红菇属（H 、JH 、FH ）土壤真菌的丰富度高于乳菇属（DZ ）；H 、JH 、FH 、DZ 共有OTUs 463个，H 特有121个；门水平上，H 子实体下土壤真菌中子囊菌门与担子菌门丰度较JH 、FH 、DZ 高，DZ 与H 、JH 、FH 在球囊菌门、芽枝霉门丰富度上呈极显著差异；属水平上，H 子实体下土壤真菌红菇属、丝盖伞属丰度较JH 、FH 、DZ 高，DZ 中青霉属、Saitozyma 、黄丝曲霉属较其他组别丰度高，大团囊菌属、喇叭菌属、小球腔菌属、Paraphaeosphaeria 、丝盖伞属等与H 关联度高，与JH 、FH 、DZ 关联度较低，但H 、JH 、FH 、DZ 土壤真菌属的丰度无显著性差异；特定物种丰度方面，H 中Gliocephalotrichum humicola 、Talaromyces ruber 、玫瑰红菇较其余组别丰度高，排名前十的物种无显著性差异，但H 子实体下土壤真菌Aspergillus citocrescens 在同属间（H ，FH ，JH ）两两比较丰度差异达到显著水平。
