The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Presents the latest standards and considerations on solid biofuels technical requirements; Contains numerous examples on applications in the field of solid biofuels thermochemical conversion, as well as the state of the art in this field; Includes sustainability aspects, including life cycle assessment aspects and financial concerns for the exploitation of solid biofuels.

This book addresses the developing area of biomass for technological applications. Written by leading researchers in the field, the book differs from other literature available by providing a detailed, in-depth discussion of the characteristics of these materials. The use of biomass for technological applications is a rapidly growing area in materials engineering and green bioprocesses. In this approach, pre-treatments focus on the bioavailability of nutrients and facilitate the use of biomass for delivering byproducts (e.g. enzymes) and for bioenergy production, both of which are discussed at length in this book. In this regard, it explores various aspects of the structural complexity of residual biomass produced by agricultural, industrial and livestock activities for biotechnological purposes, and assesses both conventional and emerging pre-treatments (e.g. biological, enzymatic and physical-chemical). This book reveals the advantages of these techniques, both individually and in combination, making it an excellent resource for all readers interested in cutting-edge applications of biomass.

This Volume presents methods for quantifying microbial populations and characterising microbial communities by extracting and analysing biomarkers such as RNA, DNA and lipids. The chapters cover a wide range of topics, including: cell separation from oil-rich environments, enumeration of hydrocarbon degraders and sulphate reducers using most-probable-number techniques, and quantification by means of real-time PCR. A variety of molecular methods are described for microbial community profiling, such as phospholipid fatty acid analysis, DGGE, T-RFLP and SSCP. One chapter examines high-throughput sequencing, and provides important information on the associated procedures required for thorough data analysis. A further chapter is devoted to the characterisation of protistan communities, while the closing chapter describes multiplex fluorescent antibody microarrays for detecting microbial biomarkers. Hydrocarbon and Lipid Microbiology Protocols There are tens of thousands of structurally different hydrocarbons, hydrocarbon derivatives and lipids, and a wide array of these molecules are required for cells to function. The global hydrocarbon cycle, which is largely driven by microorganisms, has a major impact on our environment and climate. Microbes are responsible for cleaning up the environmental pollution caused by the exploitation of hydrocarbon reservoirs and will also be pivotal in reducing our reliance on fossil fuels by providing biofuels, plastics and industrial chemicals. Gaining an understanding of the relevant functions of the wide range of microbes that produce, consume and modify hydrocarbons and related compounds will be key to responding to these challenges. This comprehensive collection of current and emerging protocols will facilitate acquisition of this understanding and exploitation of useful activities of such microbes.

Abiotic stresses such as drought (water deficit), extreme temperatures (cold, frost and heat), salinity (sodicity) and mineral (metal and metalloid) toxicity limit productivity of crop plants worldwide and are big threats to global food security. With worsening climate change scenarios, these stresses will further increase in intensity and frequency. Improving tolerance to abiotic stresses, therefore, has become a major objective in crop breeding programs. A lot of research has been conducted on the regulatory mechanisms, signaling pathways governing these abiotic stresses, and cross talk among them in various model and non-model species. Also, various 'omics' platforms have been utilized to unravel the candidate genes underpinning various abiotic stresses, which have increased our understanding of the tolerance mechanisms at structural, physiological, transcriptional and molecular level. Further, a wealth of information has been generated on the role of chromatin assembly and its remodeling under stress and on the epigenetic dynamics via histones modifications. The book consolidates outlooks, perspectives and updates on the research conducted by scientists in the abovementioned areas. The information covered in this book will therefore interest workers in all areas of plant sciences. The results presented on multiple crops will be useful to scientists in building strategies to counter these stresses in plants. In addition, students who are beginners in the areas of abiotic stress tolerance will find this book handy to clear their concepts and to get an update on the research conducted in various crops at one place
