“‘Whoever denies authority and fights against it is an anarchist,’ said Sebastien Faure. The definition is tempting in its simplicity, but simplicity is the first thing to guard against in writing a history of anarchism. Few doctrines or movements have been so confusedly understood in the public mind, and few have presented in their own variety of approach and action so much excuse for confusion.” These are the opening sentences of this book, which brilliantly effaces confusion by providing a critical history of anarchist thought and practice. Mr. Woodcock traces the development of anarchism from its earliest appearances, and the rise and fall of anarchism as a movement aiming at pra...
Vitamins are a group of physiologically very important, chemically quite complex organic compounds, that are essential for humans and animals. Some vitamins and other growth factors behave as antioxidants, while some can be considered as biopigments. As their chemical synthesis is laborious, their biotechnology-based synthesis and production via microbial fermentation has gained substantial interest within the last decades. Recent progress in microbial genetics and in metabolic engineering and implementation of innovative bioprocess technology has led to a biotechnology-based industrial production of many vitamins and related compounds. Divided into three sections, this volume covers: 1. water-soluble vitamins 2. fat-soluble vitamin compounds and 3. other growth factors, biopigments, and antioxidants. They are all reviewed systematically: from natural occurrence and assays, via biosynthesis, strain development, to industrially-employed biotechnological syntheses and applications.

This new edition provides a comprehensive look at the molecular genetics and biochemical basis of fungal biology, covering important model organisms such as Aspergilli while also integrating advances made with zygomycetes and basidiomycetes. This book groups a total of 15 chapters authored by expert scholars in their respective fields into four sections. Five chapters cover various aspects of gene expression regulation. These range from regulation in organismal interactions between parasitic fungi and their host plant, heavy metal stress and global control of natural product genes to conidiation and regulation through RNA interference. Two chapters are dedicated to signal transduction, highlighting MAP-kinase-dependent signaling and heterotrimeric G-proteins. Fungal carbohydrates are the subject of the third section, which addresses both polymeric cell wall carbohydrates and trehalose as an important, low molecular weight carbohydrate. The fourth section emphasizes the metabolism of major elements (carbon, nitrogen, sulfur) and critical cellular pathways for primary and secondary products.
