The generation of well-defined nanoparticles of excellent size and
shape involves physical and chemical methodologies that are
complicated, expensive, and produce hazardous toxic waste that is
harmful to the environment and to human health. In order to combat
the disadvantages of these methods, scientists have created "the
biological method," a new synthetic methodology that serves as a
proper alternative to physical and chemical methodologies because
of its easy utility, low cost, rapid synthesis, controlled size
characteristics, controlled toxicity, and eco-friendliness.
Nanobiotechnology is the science in which living matter can be
manipulated and exploited to produce materials within the
nano-scale. It is a multidisciplinary field of science framed by
biology, chemistry, engineering, materials, and life sciences.
Different biological entities can be exploited to yield
biologically synthesized nanomaterials including bacteria,
actinomycetes, yeast, fungi, viruses, algae, plant extracts, and
agro-industrial waste extracts. This book represents a
comprehensive review concerning the state of the art in
nanobiotechnology, emphasizing the use of diverse biological
entities in the science, and its versatile applications. It
describes currently existing methodology with the latest published
references, and provides safety information. It serves as the ideal
guide for scientists interested in exploring nanobiotechnology.
The term 'botanical aesthetics' refers to the visual and embodied
modes which inform the perception, understanding, and appreciation
of plant life. Green Sense is an interdisciplinary study of human
aesthetic relationships to wild plants and the 'cultures of flora'
that may characterise a region. The book explores botanical
aesthetics through a study of the South-West region of Western
Australia; a biodiversity 'hotspot' of international standing.
Through a diverse range of materials, approaches, and perspectives,
this title points to the interplay of values informing cultures of
flora-from visual aesthetics and scientific knowledges, to embodied
appreciations and sensory entanglements. The book provides a model
for better understanding human relationships to wild plants, and
offers an intriguing journey through science, poetry, philosophy,
ethnography, Indigenous Australian knowledges, regional tourism,
and memory studies. John Charles Ryan is a Postdoctoral Research
Fellow in the Centre for Research in Entertainment, Arts,
Technology, Education, and Communications (CREATEC) and the School
of Communications and Arts at Edith Cowan University in Mount
Lawley, Western Australia. Prior to his appointment, he completed a
research doctorate with a focus on ecocultural studies of
Australian biodiversity and creative responses to place. In 2003,
he was awarded a Master of Arts degree in Values and the
Environment (MAVE) from the University of Lancaster, UK. With the
artist Ellen Hickman, he is co-author of Two with Nature, published
in 2012. He is also a contributor to a forthcoming collection
Fremantle Poets 3: Performance Poets. His ecocultural research has
appeared in Continuum; Australian Humanities Review; Australian
Garden History; Nature and Culture; New Scholar; and
Transformations. Green Sense will appeal to readers interested in
the sensory and embodied aspects of human relationships to plants.
This book provides an up-to-date review and analysis of the
carrot's nuclear and organellar genome structure and evolution. In
addition, it highlights applications of carrot genomic information
to elucidate the carrot's natural and agricultural history,
reproductive biology, and the genetic basis of traits important in
agriculture and human health. The carrot genome was sequenced in
2016, and its relatively small diploid genome, combined with the
fact that it is the most complete root crop genome released to date
and the first-ever Euasterid II genome to be sequenced, mean the
carrot has an important role in the study of plant development and
evolution. In addition, the carrot is among the top ten vegetables
grown worldwide, and the abundant orange provitamin A carotenoids
that account for its familiar orange color make it the richest crop
source of vitamin A in the US diet, and in much of the world. This
book includes the latest genetic maps, genetic tools and resources,
and covers advances in genetic engineering that are relevant for
plant breeders and biologists alike.
Photosynthesis has been an important field of research for more
than a century, but the present concerns about energy, environment
and climate have greatly intensified interest in and research on
this topic. Research has progressed rapidly in recent years, and
this book is an interesting read for an audience who is concerned
with various ways of harnessing solar energy.Our understanding of
photosynthesis can now be said to have reached encyclopedic
dimensions. There have been, in the past, many good books at
various levels. Our book is expected to fulfill the needs of
advanced undergraduate and beginning graduate students in branches
of biology, biochemistry, biophysics, and bioengineering because
photosynthesis is the basis of future advances in producing more
food, more biomass, more fuel, and new chemicals for our expanding
global human population. Further, the basics of photosynthesis are
and will be used not only for the above, but in artificial
photosynthesis, an important emerging field where chemists,
researchers and engineers of solar energy systems will play a major
role.
Early anthropological evidence for plant use as medicine is 60,000
years old as reported from the Neanderthal grave in Iraq. The
importance of plants as medicine is further supported by
archeological evidence from Asia and the Middle East. Today, around
1.4 billion people in South Asia alone have no access to modern
health care, and rely instead on traditional medicine to alleviate
various symptoms. On a global basis, approximately 50 to 80
thousand plant species are used either natively or as
pharmaceutical derivatives for life-threatening conditions that
include diabetes, hypertension and cancers. As the demand for
plant-based medicine rises, there is an unmet need to investigate
the quality, safety and efficacy of these herbals by the
"scientific methods". Current research on drug discovery from
medicinal plants involves a multifaceted approach combining
botanical, phytochemical, analytical, and molecular techniques. For
instance, high throughput robotic screens have been developed by
industry; it is now possible to carry out 50,000 tests per day in
the search for compounds, which act on a key enzyme or a subset of
receptors. This and other bioassays thus offer hope that one may
eventually identify compounds for treating a variety of diseases or
conditions. However, drug development from natural products is not
without its problems. Frequent challenges encountered include the
procurement of raw materials, the selection and implementation of
appropriate high-throughput bioassays, and the scaling-up of
preparative procedures. Research scientists should therefore arm
themselves with the right tools and knowledge in order to harness
the vast potentials of plant-based therapeutics. The main objective
of Plant and Human Health is to serve as a comprehensive guide for
this endeavor. Volume 1 highlights how humans from specific areas
or cultures use indigenous plants. Despite technological
developments, herbal drugs still occupy a preferential place in a
majority of the population in the third world and have slowly taken
roots as alternative medicine in the West. The integration of
modern science with traditional uses of herbal drugs is important
for our understanding of this ethnobotanical relationship. Volume 2
deals with the phytochemical and molecular characterization of
herbal medicine. Specifically, it focuess on the secondary
metabolic compounds, which afford protection against diseases.
Lastly, Volume 3 discusses the physiological mechanisms by which
the active ingredients of medicinal plants serve to improve human
health. Together this three-volume collection intends to bridge the
gap for herbalists, traditional and modern medical practitioners,
and students and researchers in botany and horticulture.
Microbes are ubiquitous in nature. Among microbes, fungal
communities play an important role in agriculture, the environment,
and medicine. Vast fungal diversity has been associated with plant
systems, namely epiphytic fungi, endophytic fungi, and rhizospheric
fungi. These fungi associated with plant systems play an important
role in plant growth, crop yield, and soil health. Rhizospheric
fungi, present in rhizospheric zones, get their nutrients from root
exudates released by plant root systems, which help with their
growth, development, and microbe activity. Endophytic fungi
typically enter plant hosts through naturally occurring wounds that
are the result of plant growth, through root hairs, or at epidermal
conjunctions. Phyllospheric fungi may survive or proliferate on
leaves depending on material influences in leaf diffuseness or
exudates. The diverse nature of these fungal communities is a key
component of soil-plant systems, where they are engaged in a
network of interactions endophytically, phyllospherically, as well
as in the rhizosphere, and thus have emerged as a promising tool
for sustainable agriculture. These fungal communities promote plant
growth directly and indirectly by using plant growth promoting
(PGP) attributes. These PGP fungi can be used as biofertilizers and
biocontrol agents in place of chemical fertilizers and pesticides
for a more eco-friendly method of promoting sustainable agriculture
and environments. This first volume of a two-volume set covers the
biodiversity of plant-associated fungal communities and their role
in plant growth promotion, the mitigation of abiotic stress, and
soil fertility for sustainable agriculture. This book should be
useful to those working in the biological sciences, especially for
microbiologists, microbial biotechnologists, biochemists, and
researchers and scientists of fungal biotechnology.
Sugarcane enjoys a prominent position among agro-industrial crops
and is commercially grown in 115 tropical and subtropical countries
around the world. However, fluctuations in sugar prices have forced
the sugarcane industry worldwide to broaden its revenue base by
moving from single-commodity manufacturing to a range of
value-added products. Utilizing the by-products in an innovative
manner to create value-added products is the new course of action
for sugar-producing countries. For many years sugarcane was
regarded as a single-product crop, i.e., only useful for producing
sugar. Its actual potential is now increasingly being recognised by
the industry and there is a growing trend toward the manufacturing
of allied products from sugarcane. Therefore, the focus is now on
the establishment of sugar-agro-industry complexes, processing not
just sugar but a range of other products. This book provides a
comprehensive overview of sugarcane not only as a source of
sweetening agents but also for many other uses, including as a
source of bio-energy. It also explores the trend of sugar
consumption and suggests practices to curb the consumption of sugar
products in order to tackle obesity and reduce public health costs.
The book underscores the need to diversify sugarcane and highlights
means of doing so, while also addressing various innovations and
technologies being developed in connection with sugar, sugar
derivatives, and sugar industry by-products for sustainable
utilization in the sugar-agro industry. Accordingly, it offers a
valuable resource for professionals and R&D units in the sugar
industry, and for students of agronomy and related fields.
This book highlights the latest findings on fundamental aspects of
composting, the interaction of various microorganisms, and the
underlying mechanisms. In addition to addressing modern tools and
techniques used for composting research, it provides an overview of
potential composting applications in both agriculture and
environmental reclamation. Composting is the process of organic
waste decomposition, mediated by microorganisms. The end-product is
called 'compost' and can be used as a supplement to improve soil
fertility. As the municipal waste generated in most developing
countries contains a substantial amount of organic matter suitable
for composting, this technology offers a win-win opportunity for
stakeholders in terms of disposing of organic waste and providing
organic fertilizers for agriculture. In addition, using compost
reduces the dependency on harmful chemical fertilizers, and
represents a sustainable and environmentally friendly alternative.
