Book Description
This book tells the story behind the first Spirodela genome sequencing project. Further, it describes the current genomics applications of these findings, and efforts to sequence new genomes within the family. The closing chapters address the sequencing of the over 1 Gigabase Wolffia genomes, which could have major impacts on genome evolution and agricultural research. The duckweed or Lemnaceae family is a collection of 5 genera and 37 species of the smallest, fastest-growing flowering plants. Many of these aquatic monocotyledonous plants can grow all over the world, in a variety of climates. Given their simplified and neotenous morphology, duckweeds have been researched for several decades as a model species for plant physiology and ecotoxicological research, contributing to our understanding e.g. of flowering response, plant circadian systems, sulfur assimilation pathways and auxin biosynthesis. In addition, duckweed-based treatment has been a favorite and feasible means, especially in developing countries, of removing phosphorus and pharmaceutical chemicals from sewage and wastewater. With a dry annual mass yield per hectare of up to 80 tonnes (equivalent to 10 tonnes of protein), duckweed is also a promising aquatic crop in new modern and sustainable agriculture. Besides being an excellent primary or supplemental feedstock for the production of livestock and fish, duckweed biomass can be utilized as a potential resource for human nutrition, biofuel, or bioplastics, depending on water quality as well as protein or starch accumulating procedures. These academic and commercial interests have led to international efforts to sequence the Spirodela polyrhiza genome, the smallest and most ancient genome in the family.

Book Description
Duckweed (L.gibba)-covered sewage lagoons (DSLs) are low cost treatment systems, especially suitable for warm climates, or in lands where there are warm seasons. This study attempts to assess DSL system as a new technology, contributing to the understanding of the different mechanisms in the system. Duckweed-covered sewage lagoons could either replace complete wastewater stabilization ponds (WSPs) or be introduced as a second stage in an integrated WSP-DSL treatment system, which could then be used for purifying municipal wastewater, achieving suitable effluent for reuse in agriculture. The duckweed harvested from DSL systems has, in itself, an intrinsic economic value.

Book Description
The smallest flowering plant, on Earth, is one of the most powerful, and widespread: duckweed. Usually, considered a nuisance, duckweed, upon close examination, is an impressive crop, in photosynthetic value. Ethanol, an industry dominated by the Corn Industry (King Corn), faces many challenges, including large water draws, rising fertilizer costs, large diesel fuel bills, and unintended impacts on Food markets. Corn, as a choice for ethanol production, pits food, versus fuel, for agricultural resources, increasing stresses between fundamental markets. An ideal source of biomass, for ethanol production, would not be a food crop, rather, a waste-crop. King Corn, dominates current domestic ethanol production markets, worth billions, each year. Supported with Federal Farm Subsidies, worth billions of dollars annually, the corn industry dictates the US ethanol markets, using Corn as the principle feedstock crop. At first glance, Corn, is an odd choice for ethanol production. Corn, began as a wild seed crop, domesticated by ancient man. Before the modern age, thousands of years of selective breeding, produced a Corn rich in proteins, and high in nutritional value. Modern Corn, has been engineered to go "the other direction," and reduce Corn's Protein, and increase Corn's Starch (Carbohydrate) production. The "Starch" in corn, is used for Ethanol production, and other by-products, such as Corn Syrup, and Distillers Dried Grains and Solubles (DDGS). Duckweed, is a choice for bulk biomass, which offers significant advantages over corn. Duckweed advantages include, lower energy costs, lower water resources, lower fertilizer costs, doesn't require valuable farmland, doesn't compete in Food markets, has higher Starch yield, per acre. Duckweed, in a controlled environment, can be grown, year round, and in diverse locations. Corn, as a bulk source of Starch production, competes with Food markets, drinks thousands of gallons of water, per gallon Ethanol produced, requires large diesel fuel bills for growing, and harvesting, requires large amounts of fertilizers, and lower's the nutritional value of Corn on purpose, to produce more starch, reducing protein production, and nutritional value.

Book Description
Effective treatment of nitrogen containing wastewater is required to prevent eutrophication and groundwater pollution. This thesis shows that effective treatment may be combined with substantial nitrogen recovery in duckweed-based waste stabilization ponds.

Book Description
Because in a giant city, sometimes the smallest things get overlooked. Tiny New York peeks into the city’s nooks and crannies to find the little things that tell the real New York story. Because in New York, Tiny isn’t cute. It’s tough. Tiny doesn’t wait for handouts. It hustles. Tiny isn’t insignificant. It’s precise. Tiny isn’t a jack-of-all-trades. It’s the master of one. There are plenty of books about New York City. But there has never been a book about the smallest things in the biggest city.

Book Description
As we enter a new millennium, the environmental issues faced by both developing and industrialised nations are as pressing as ever. Environmental biotechnologies are increasingly being viewed as a major weapon against environmental damage. Cleaner production is part of this strategy and yet there is still widespread ignorance about this emerging technology. Environmental Biotechnology and Cleaner Bioprocesses provides this information at various levels, from introductory to advanced. The first section covers the development of cleaner bioprocesses within the framework of sustainable development. Aspects of environmental policy for small and medium businesses are then discussed using case studies to illustrate principles. The second section covers the recycling and treatment of organic waste, including the use of aquatic plants and microalgae for wastewater treatment and recovery of nutrients. Section three covers bioremediation technologies and finally, section four is dedicated to emerging cleaner bioprocesses and environmentally sound products. All chapters have been written and edited by leading authorities in the field. Students and professionals interested in environmental biotechnology and cleaner production will find the background information and detail they require in this one convenient source.
