Vi kan ikke se den, ikke høre den, ikke mærke den, men den er overalt: en verden af levende organismer så små, at vi ikke kan få øje på dem. Mikrobiologiens mikroorganismer.Mikroorganismerne er på en lang række måder de vigtigste væsener på planeten. Men vi har haft dem ude af øje og ude af sind. Indtil nu. De seneste årtier er der sket en eksplosion i forståelsen af hvor vigtige mikroorganismerne er for vores liv. Der breder sig i forskningsverdenen en forståelse af at mikroorganismer kan rumme nøglen til at løse mange af de store problemer, vi står overfor på planeten: klima, rent vand, fødevarer, sygdomsbekæmpelse, biodiversitet. Mikroorganismerne kan blive vores usynlige allierede. En utrolig succeshistorie om mikroskopiske små væsener, der dukker op fra usynlighedens glemsel for at indtage hovedrollen idet drama, der skal udfoldes i de næsteårtier og århundreder: At redde verden.

The genus Arthrospira belongs to the Oscillatoriaceae family and comprises the group of cylindrical filamentous photosynthesizing cyanobacteria, known as blue-green microalgae. It has been used as food for humans for thousands of years. In 1974 it was declared THE BEST FOOD FOR THE FUTURE by the UN WORLD FOOD CONFERENCE, which aimed to eradicate hunger, food insecurity and malnutrition. For the WHO - UN World Health Organization - Arthrospira is an interesting food for many reasons, such as being rich in protein and iron and because it can be consumed without any risk. In commercial production, the choice of the composition of the culture medium is of great importance because 15 to 25% of the total production costs are due to the culture medium used for the development of the microorganism.

Covid-19 has been a global challenge for more than two years. We do not know exactly how and when this, the worst epidemic in the last 100 years will end, but we are almost sure that it will keep mutating and remain with us well into the future. As globalization and urbanization increase, we will continue to encounter unknown viruses and the so-called Disease X. Since there is no cure yet, we must research and deploy standard and alternative measures.In China, more than 500 plagues were recorded in the past 3000 years, Traditional Chinese Medicine grew up struggling with those mainstream medical crises. TCM has formed mature theories on integrated treatment plans and has accumulated and recorded rich therapeutic experiences.Diseases like influenza, SARS and Covid-19 have utilized TCM theories and have benefitted from its robust history. This book details TCMÊ¿s role in the treatment of Covid-19 in three primary parts.Initially a retrospection of TMC history of plagues is offered, including the earliest theories of antiserum therapy and ancient vaccines and variolation. This section also includes information on the various schools of TCM and their various approaches in understanding and treating plagues. Next, we explore modern TCM theories on the etiology and pathogenesis of Covid-19. Finally, we discuss prevention strategies as well as treatment of accompanying and underlying patterns and immune disorders associated with Covid-19. We include examples of how early physicians dealt with contagions and patients and how they tried to do their work, but not contract the diseases they were treating. We also include a section on the various stages of Covid-19 infection from initial to critical as well as the sequelae of this infection. TCM has been found to be especially useful in the post-infection phase for patients with lingering symptoms.This book is based on a combination of scientific research emanating from Western as well as TCM sources.For practitioners of Chinese Medicine, we feel this book deserves your attention.

Bioprospecting is underway to replace nitrogen fertilizers with bacteria that fix atmospheric nitrogen (N2) and convert it into a form that the plant is capable of assimilating, such as Gluconacetobacter diazotrophicus, an obligate endophytic bacterium and the only species of its kind capable of fixing nitrogen. This bacterium is also endowed with other characteristics, such as the biosynthesis of levan, an important biomolecule for the scientific community, as it can be used in the pharmaceutical industry as a hypocholesterolemic, anticarcinogenic, prebiotic and modified drug release agent. The aim of this research was to isolate, morphologically characterize and select levain-producing strains from endophytic bacteria with characteristics similar to G. diazotrophicus associated with two varieties of sugarcane grown in the São José do Rio Preto region (SP).

Nosokomiale Infektionen werden auch als im Krankenhaus erworbene Infektionen bezeichnet und sind definiert als Infektionen, die mindestens 48 bis 72 Stunden nach der Aufnahme ins Krankenhaus festgestellt werden. Nosokomiale Infektionen gelten als Haupthindernis für die Verbesserung des Gesundheitszustands und stellen eine große Bedrohung für die öffentliche Gesundheit dar, und dies trotz des Fortschritts in der Medizintechnik und Medizin und des deutlichen Rückgangs von Infektionskrankheiten. Die Centers for Disease Control and Prevention schätzen, dass jedes Jahr 2 Millionen Patienten an nosokomialen Infektionen leiden und fast 100.000 von ihnen sterben. Diese Infektionen verursachen jährlich bis zu 4,5 Milliarden Dollar an zusätzlichen Kosten im Gesundheitswesen. In den meisten Studien über nosokomiale Infektionen werden Parasiten als Hauptrisikofaktor für den Erwerb einer nosokomialen Infektion ignoriert, obwohl sie leicht übertragen werden können und insbesondere in Entwicklungsländern resistent gegen Desinfektionsmittel sind. Die meisten nosokomialen Parasiteninfektionen betreffen Patienten mit Risikofaktoren wie Patienten mit Radio- und Chemotherapie, immungeschwächte Patienten und solche, die HIV-positiv sind.

Short Sketch About BookThis book of study reveals that twenty five isolates were recovered as phosphate solubilizing bacteria (PSB) from rhizosphere soil of paddy plants from four different locations of paddy field in Alwarkurichi village of Tenkasi District. Phosphate solubilizing bacterial population ranged from 30-50 × 102 CFU/g in Pikovskayäs agar medium, 20-30 × 102 CFU/g in hydroxy apatite agar medium and 10-20 × 102 CFU/g in soil extract agar medium. Among the tested isolates, highest load of phosphate solubilizers were found as the best in solubilizing phosphate 102 dilutions with the drop in neutral pH in Pikovskayäs agar medium. The results indicated that the rhizosphere soils of the study area inhabit phosphate solubilizing bacteria with great potential to be used as the commercial production of phosphatase enzymes. This study examines the effect of herbicide, one-shot on phosphate solubilizing bacterial activities like phosphate solubilization by herbicide resistance pattern. Here, the selected herbicide, one-shot was applied at two different concentrations of 10 ppm and 50 ppm against the phosphate solubilizers of Micrococcus sp., Bacillus sp. and Pseudomonas sp.

This book deals with the importance of water, which is one of the natural resources essential to human life and the balance of ecosystems, as well as the economy in the primary and secondary sectors. However, the decline and quality of water has become a global problem that jeopardises human survival, requiring monitoring by the competent bodies and the population in general, since water sources are subject to contamination by pathogenic micro-organisms, responsible for the transmission of waterborne diseases. With this in mind, the aim is to carry out a microbiological analysis (coliforms) of the water distributed from the underground water supply microsystem to homes in the Urumari II neighbourhood in Santarém-PA, where samples were sampled, collected and analysed using the Most Probable Number (MPN) technique using the multiple tube method. In view of the irregularities found, the presence of total coliforms and thermotolerant coliforms does not comply with the maximum legal limits permitted by ordinance 2.914/2011.

Ce livre traite de l'importance de l'eau, qui est l'une des ressources naturelles essentielles à la vie humaine et à l'équilibre des écosystèmes, ainsi qu'à l'économie dans les secteurs primaire et secondaire. Cependant, la diminution et la qualité de l'eau sont devenues un problème mondial qui met en péril la survie de l'humanité, nécessitant une surveillance de la part des organismes compétents et de la population en général, car les sources d'eau sont sujettes à la contamination par des micro-organismes pathogènes, responsables de la transmission de maladies d'origine hydrique. Dans cette optique, l'objectif est de réaliser une analyse microbiologique (coliformes) de l'eau distribuée par le microsystème souterrain d'approvisionnement en eau aux habitations du quartier Urumari II à Santarém-PA, où des échantillons ont été prélevés, collectés et analysés selon la technique du nombre le plus probable (NPP) en utilisant la méthode des tubes multiples. Compte tenu des irrégularités constatées, la présence de coliformes totaux et de coliformes thermotolérants ne respecte pas les limites maximales légales autorisées par l'ordonnance 2.914/2011.
