Hardback. Condition: New. Understand the properties and applications of one of the world's most ubiquitous flora Lichen is a single entity comprising two or more organisms-most typically algae and fungus-in a symbiotic relationship. It is one of the planet's most abundant categories of flora, with over 25,000 known species across all regions of the globe. Lichens' status as a rich source of bioactive metabolites and phytochemicals, as well as their potential as bio-indicators, has given them an increasingly prominent role in modern research into medicine, cosmetics, food, and more. Chemistry, Biology and Pharmacology of Lichen provides a comprehensive overview of these bountiful flora and their properties. It provides not only in-depth analysis of lichen physiology and ecology, but also a thorough survey of their modern and growing applications. It provides all the tools readers need to domesticate lichen and bring their properties to bear on some of humanity's most intractable scientific problems. Chemistry, Biology and Pharmacology of Lichen readers will also find: Applications of lichen in fields ranging from food to cosmetics to nanoscience and beyondDetailed discussion of topics including lichen as habitats for other organisms, lichens as anticancer drugs, antimicrobial properties of lichen, and many moreDetailed discussion on key bioactive compounds from lichens Chemistry, Biology and Pharmacology of Lichen is ideal for scientists and researchers in ethnobotany, pharmacology, chemistry, and biology, as well as teachers and students with an interest in biologically important lichens. It is gratifying to see the enthusiasm of Indian mycologists for lichens grow over the last 25 years, especially in their possible exploitation. That this book has a staggering 63 contributors, of which all but seven are from India or Pakistan, is a testament to that enthusiasm. Following a series of nine chapters on general aspects of lichen biology, conservation and ecology, are ten on different aspects of actual or prospected applications. These cover traditional uses, therapeutic potential of bioactive compounds, antioxidant properties, antimicrobial activities, anticancer drugs, food value, perfumery and cosmetics, bioindication, and nanoparticles. One contribution compiles ethnobotanical and pharmacological properties of four particular genera (Cetraria, Cladonia, Parmelia s.lat., and Usnea). The compilations of pertinent very scattered publications and reports will be of value for anyone wishing to explore particular activities further, especially as starting points for fresh research. However, it has to be recognized that many of the studies commented on, especially in relation to potential medical applications, are based on individual rather small-scale studies (and not always on precisely identified material). Further, in many chapters, published reports are carefully compiled but generally accepted without indications of their limitations. I was concerned to see that in the ch.…

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Cyanobacteria or blue green algae are the pioneer oxygenic phototrophs on earth whose distribution around the world is surpassed only by bacteria. Cyanobacteria and similar organisms produced most of the oxygen found in Earth's atmosphere, which implies that early photosynthetic organisms would have lived in an atmosphere that was rich in CO2 and poor O2 (David et al, 2005). It was shown that three common cyanobacterial species can grow under conditions that resemble those thought to have existed on early Earth: very high pCO2 and low pO2. Fossil evidence points to their presence in geographically diverse regions during the Precambrian (2 or more than 3.5 billion years ago). They are a large and morphologically diverse group of phototrophic prokaryotes, which occur in almost every habitat on earth. This versatility may explain the remarkable lack of morphological (and presumably physiological) change seen in 3.5- billion-year-old fossilized BGA and their modern day counterparts (Adams, 2000). 88 pp. Englisch.…
