Actinobacteria
This book describes isolated actinobacteria from different environments, and how these can be used to bioremediate heavy metals and pesticides in contaminated sites. It also describes how free-living actinobacteria acquire the capability to produce nodules in plants and how this factor could be important for accelerating the degradation of pesticides in soils or slurries. Some chapters show how actinobacteria can be used to produce industrial enzymes and metabolites under different physicochemical conditions for use in the food industry. This book will interest professionals involved with waste management, environmental protection, and pollution abatement.
Environmental Nexus Approach
Environmental Nexus Approach: Management of Water, Waste, and Soil establishes linkages between environmental resources, such as water, waste, and soil, in order to facilitate sustainable management of these resources. It shows the nexus approach as a policy-relevant means of environmental management by focusing on integrated management of water, waste, and soil resources. It synthesizes interdisciplinary theory, concepts, definitions, models, and findings involved in complex global sustainability problem-solving, making it an essential guide and reference. It includes real-world examples and applications making the book accessible to a broader interdisciplinary readership. Features: Explore...
Microbial Metabolism of Xenobiotic Compounds
Xenobiotic compounds including pesticides, nitrophenols, pyridine, polycyclic aromatic compounds and polychlorinated biphenyls are widely spread in environment due to anthropogenic activities. Most of them are highly toxic to living beings due to their mutagenic and carcinogenic properties. Therefore, the removal of these compounds from environment is an essential step for environmental sustainability. Microbial remediation has emerged as an effective technology for degradation of these xenobiotic compounds as microorganisms have unique ability to utilize these compounds as their sole source of carbon and energy. The primary goal of this book is to provide detailed information of microbial degradation of many xenobiotic compounds in various microorganisms.
Toxicity of Aquatic System and Remediation
The eco-friendly remediation technologies for the degraded environment are indeed the “need of the hour”. Even though the regulatory mechanisms are in place to control the discharge of untreated contaminants into the natural environment, still, we could see a different picture; hence, remediation and restoration of the environment becomes an ardent requisite. The present-day fast pace of industrialization without proper disposal planning is impacting the water bodies adversely, generating the need for green management technologies. It is worth mentioning that these environment-friendly technologies are most cost-effective as well. The advancements in biotechnology have paved the way to m...
Bioremediation in Latin America
The book compiles an update information about the state of bioremediation in emerging Latin American countries. Some of the studied regions are sites that suffered decades of pollution by agrochemicals, heavy metals and industrial waste due to the lack of control by government regulations. Such is the case of Northern Argentina, where were illegally deposited over 30 tn of obsolete organochlorine pesticides in 1994. The content has focused in the use of native organisms (from bacteria to plants) as a viable solution to the problem of pollution, using low-cost and powerful techniques, socially well accepted and appropriate from the environmental point of view. In this context, levels of pesticide found in the Latin American population are informed. It was also displayed as a multidisciplinary approach based on concerns of a diverse group of researchers (biochemists, biologists, chemical engineers and geneticists) about a global problem, dealing with specific cases of study, with a view to project their findings to worldwide. In this regard, researchers provide their findings to regulatory sectors, whom could make appropriate decisions.
Bioremediation of Agricultural Soils
The quality of agricultural soils are always under threat from chemical contaminants, which ultimately affect the productivity and safety of crops. Besides agrochemicals, a new generation of substances invades the soil through irrigation with reclaimed wastewater and pollutants of organic origin such as sewage sludge or cattle manure. Emerging pollutants such as pharmaceuticals, nanomaterials and microplastics are now present in agricultural soils, but the understanding of their impact on soil quality is still limited. With focus on in situ bioremediation, this book provides an exhaustive analysis of the current biological methodologies for recovering polluted agricultural soils as well as monitoring the effectiveness of bioremediation.
Patogeny w mikrobiologii
Często mówi się o całym gatunku bakterii jako chorobotwórczym, gdy zostanie zidentyfikowany jako przyczyna choroby. Jednak współczesny pogląd jest taki, że patogeniczność zależy od całego ekosystemu drobnoustrojów. Bakteria może uczestniczyć w zakażeniach oportunistycznych u gospodarzy z obniżoną odpornością, nabywać czynniki zjadliwości przez infekcję plazmidem, przenosić się w inne miejsce w gospodarzu lub reagować na zmiany w ogólnej liczbie obecnych bakterii. Na przykład zakażenie węzłów chłonnych krezki myszy Yersinia może utorować drogę do dalszego zakażenia tych miejsc przez Lactobacillus prawdopodobnie przez mechanizm "blizn immunologicznych". Za...
醫學微生物學I：病原體和人類微生物組
病原體可以通過幾種途徑侵入宿主。主要途徑具有不同的事件發生時間框架，但是土壤具有最長或最持久的潛在病原體潛藏潛力。由傳染原引起的人類疾病被稱為致病性疾病。人類微生物組是所有 microbiota 的集合 microbiota 駐留在人體組織和生物流體上或內部以及它們所處的相應解剖部位，包括皮膚，乳腺，胎盤，精液，子宮，卵巢濾泡，肺，唾液，口腔粘膜，結膜，膽道和胃腸道。本書的內容：病原體，Pri病毒，病毒，病原細菌，真菌，病原真菌，人類寄生蟲，原生動物，寄生蟲，人類寄生蟲清單，臨床微生物學，宿主-病原...
Smittefarlige organismer i mikrobiologi
Det er vanlig å snakke om en hel bakterieart som sykdomsfremkallende når den identifiseres som årsaken til en sykdom. Imidlertid er det moderne synet at patogenisitet avhenger av det mikrobielle økosystemet som helhet. En bakterie kan delta i opportunistiske infeksjoner i immunkompromitterte verter, skaffe virulensfaktorer ved plasmidinfeksjon, bli overført til et annet sted i verten eller svare på endringer i det totale antallet andre bakterier som er til stede. For eksempel kan infeksjon av mesenteriske lymfekjertler hos mus med Yersinia gjøre det mulig å fortsette infeksjonen på disse nettstedene ved Lactobacillus, muligens ved en mekanisme for "immunologisk arrdannelse". Innhold...
Mikroorganisma patogen
Adalah umum untuk membicarakan keseluruhan spesies bakteria sebagai patogen apabila dikenal pasti sebagai penyebab penyakit. Walau bagaimanapun, pandangan moden adalah bahawa patogenik bergantung pada ekosistem mikroba secara keseluruhan. Bakteria boleh mengambil bahagian dalam jangkitan oportunis pada host imunocompromised, memperoleh faktor virulensi oleh jangkitan plasmid, dipindahkan ke laman web lain di host, atau bertindak balas terhadap perubahan jumlah keseluruhan bakteria lain yang ada. Contohnya, jangkitan pada tikus kelenjar getah bening mesenterik dengan Yersinia dapat membersihkan jalan untuk meneruskan jangkitan laman web ini dengan Lactobacillus, mungkin dengan mekanisme "paru...
