Basic Concepts in Environmental Biotechnology
The book includes current and emerging concepts in the areas of environmental biotechnology such as pollution sources, control and measurement, solid waste management, bioremediation, biofuels, biosensors, bioleaching, conservation biotechnology and more. The book also includes recent innovations made in this field and incorporates case studies to help in understanding the concepts. This book applies principles from multidisciplinary sciences of environmental engineering, metabolic engineering, rDNA technology and omics to study the role of microbes and plants in tackling environmental issues. It also includes content related to risk assessment and environmental management systems. Each chap...
Rediscovering Earthworms
This book is a concise and well-illustrated treatment of the conventional knowledge and modern utilities of earthworms. The first two chapters deal with earthworm morphology, food relationship, behavior, functional role, interaction with soil biota, and the influence of environmental factors. Earthworms found in the tropics and sub-tropics are also discussed in this section. The third chapter provides a good account of utilizing species of worms to produce high value manure through vermitechnology and its application in agriculture. The nutritional and medicinal values of earthworms are illustrated in the fourth chapter, while the fifth c provides information on how earthworms are used successfully as indicators of ecological perturbations, soil quality and for remediation of contaminated soils. The book will immensely benefit students, faculty and researchers in biological, agricultural and environmental sciences. It is also a source of information for anyone interested in knowing more about earthworms.
Vermiculture Revolution
A revolution is unfolding in vermiculture studies (rearing of useful earthworms species) for multiple uses in environmental protection and sustainable development. The global scientific community is searching for a technology which should be 'economically cheaper' (to be afforded by all nations), 'environmentally sustainable' (friendly to the environment) and 'socially acceptable' (beneficial to the society). Vermiculture Biotechnology with the use of earthworms combines all these virtues together. Vermiculture (rearing of earthworms) is a 'big business' today and they are also helping in 'employment generation' and 'poverty eradication programs' in several developing countries. This book reviews research on earthworms and how they promise to provide cheaper solutions to several social, economic and environmental problems of human society.
Organic Fertilizers
Organic fertiliser refers to materials used as fertiliser that occur regularly in nature, usually as a by product or end product of a naturally occurring process. Organic fertilisers such as manure have been used in agriculture for thousands of years; ancient farmers did not understand the chemistry involved, but they did recognise the benefit of providing their crops with organic material. Interest in organic farming is growing world-wide as sustainable agricultural practice nowadays. Organic fertilisers are sustained sources of nutrients due to slow release during decomposition. By increasing soil organic matter, organic farming can reinstate the natural fertility of the damaged soil, which will improve the crop productivity to feed the growing population. Organic fertilisers enhance the natural soil processes, which have long-term effects on soil fertility. The book is a very valuable compilation in this direction.
Microremediation, Phytoremediation and Vermiremediation Biotechnologies for Contaminated Lands and Soil
Bioremediation is a soft bioengineering technique to clean up contaminated lands and soils using microbes, plants and earthworms. It is also a technique to stabilise the eroded lands and prevent soil erosion. Microbes are adapted to thrive in 'adverse conditions' of high acidity, alkalinity, toxicity and high temperature. Under favourable conditions of growth, microbes can biodegrade and biotransform the complex hazardous organic chemicals into simpler and harmless ones. Environmentalists are viewing microbes such as yeast, bacteria, algae, diatoms and actinomycetes as an 'eco-friendly nano-factories' for metal remediation. This book addresses these issues regarding the benefits of microbes, plants and earthworms in bioremediation.
Concrete
Designed for undergraduate courses in civil engineering and construction materials and for practicing professional engineers. Also serves as an excellent resource in upper level concrete materials courses. The text provides a cohesive presentation of practical applications supported by detailed background information.
Earthworm Vermicompost
Earthworm's vermicompost is a nutritive organic fertiliser rich in NKP, micronutrients, and beneficial soil microbes. They are scientifically proven to be excellent growth promoters and protectors for crop plants. In experiments with corn and wheat crops it displayed excellent growth performances in terms of height of plants, colour and texture of leaves, as well as the appearance of fruiting structures. There is also less incidences of pest and disease attack and reduced demand of water for irrigation. This book discusses and presents data which suggest that the vermicompost of earthworms contributes to an increase in the yield of crops when used as a fertiliser.
Vermiculture Technology
Exploring the dramatic growth and changes in the field of vermicomposting since 1988, this comprehensive review assesses the advancements made in government-funded projects in the U.S. and UK. It discusses outdoor and indoor windrows, container systems, wedge systems, and low labor-requirements. It also examines fully-automated continuous flow vermicomposting reactor systems that can process more than 1000 tons of organic wastes per reactor. The book highlights the science and biology behind the use and efficacy of vermicomposting and details the technology of the past, present, and future.
