In this proposed book, we start with the introduction to bio-nanotechnological principles and later on discuss bio-based nanomaterials employability for a diverse range of applications from environment to energy to health care. This book provides with current trends in bio-nanotechnology for anthropogonic purposes, prospects, challenges, and way forward.

This book presents technoeconomic challenges, recent trends, and developments toward sustainable algal biofuels and biorefinery. The exponential increase in population and thus the demand for energy, the ever-rising threats to climate change with conventional fossil fuels consumption, fluctuations in fossil fuels price and geopolitical instability have made each and every country of the world to think over its energy independence and security by increasing its own domestic energy production and reducing dependence on scarce fossil fuels. The global need to shift towards a sustainable source of energy has led to the discovery of third and fourth generation biofuels, in which microalgae and their genetically modified strains have been exploited. However, these simple photosynthetic organisms are difficult to select and cultivate for the production of biodiesel. Genetic engineering has opened provisions for the introduction of desired traits to such useful strains. There are also scopes for designing of novel photobioreactors (PBRs) having strain-specific physicochemical parameters, adequate CO2 and nutrient supply, and so on. The role of microalgae in CO2 sequestration from the environment is well known fact. Wastewater treatment plants can be used a raceway pond for the microalgal biomass production, and thus, obtained biomass can be used for biofuels and biochemical production.

Mathematical modelling can be used to understand the complex phenomena inside the photobioreactor, which can be a great help to overcome the limitations related to design and scale up of PBRs. Flow hydrodynamics in PBRs has significant effect on the microalgae growth. Computational fluid dynamics (CFD) can be used to study operating and geometry factors in PBRs that influence the flow dynamics, such as the inlet gas flow rate, mixing, mass transfer, reactor geometry. The use of artificial intelligence (AI) particularly artificial neural network model (ANN model), statistical and evolutionary learning-based techniques are some innovative approaches in manipulating and optimizing productivity and costs in algal biofuel production. This book is aimed to bring several aspects of algal biorefinery and microalgal biofuel production, challenges, and future perspective of microalgal biofuel production at a single place.

Due to complex phytochemical components and associated beneficial properties, numerous medicinal and aromatic plants, in whole or parts, have been used for nutritional purposes or the treatment of various diseases and disorders in humans and animals. Essential oils from medicinal and aromatic plants (MAPs) have been exploited for product formulations of pharmaceuticals, cosmetics, food and beverage, colorants, biopesticides, and several other utility chemicals of industrial importance. There is scientific evidence of many medicinal plant extracts possessing immunomodulatory, immunostimulatory, antidiabetic, anticarcinogenic, antimicrobial, and antioxidant properties, thus demonstrating their traditional use in popular medicine. With the advent of modern technology, the exploitation of natural resources has exponentially increased in order to fulfill the demand of an increased human population with improved quality of life. The traditional agriculture and production-based supply of commodities is inadequate to meet the current demand. Biotechnological approaches are gaining importance to bridge the gaps in demand and supply. In the proposed book, medicinal and aromatic plant-based secondary metabolites have been discussed in terms of their therapeutic potential and industrial relevance. To discuss the qualitative and quantitative analysis of a range of medicinal and aromatic plants-based secondary metabolites (SMs), bioprocess development for their extraction and bioseparation, a brief overview of their industrial relevance, various tissue culturing strategies, biotechnological approaches to enhance production, scale-up strategies, management of residual biomass post extraction of target SMs is central to the idea of the proposed book. A section will explore the verticals mentioned above. In the next section, the book addresses the approaches for conserving and improving medicinal and aromatic plant genetic resources. In the third section, approaches to managing the post-harvest crop residue and secondary metabolites extracted plant biomass will be thoroughly discussed. The recent integration of artificial intelligence to improve medicinal and aromatic plant research at several levels, including the development and employment of computational approaches to enhance secondary metabolite production, tissue culture, drug design and discovery, and disease treatment, will be included in the fourth section. The book summarizes current research status, gaps in knowledge, agro-industrial potential, waste or residual plant biomass management, conservation strategies, and computational approaches in the area of medicinal and aromatic plants with an aim to translate biotechnological interventions into reality.

This book explores the scientific development in the field of algal-based nanomaterials synthesis, production methods, and commercial and utilization aspects of phyconanomaterials to address a range of problems of humanity. Nanomaterials have been recently explored for and employed in environmental remediation, biomedical applications, agriculture, food industries, energy sectors, cosmetics, biolabeling, and space due to their versatility and wide range of applicability owing to their peculiar material characteristics and other attributes. Their conventional synthesis approaches are replacing green methods as the latter is comparatively economical, energy-efficient, and eco-friendly. Biological entities and derived materials-based nanomaterials synthesis is such a green approach. Using natural systems to synthesize nanomaterials does not leave behind any toxic compounds generally produced as by-products when physical or chemical methods are employed. Phyconanotechnology, a green way of synthesizing nanomaterials, can be used to overcome this issue. In the proposed book, algal diversity-based nanomaterials synthesis and their applications will be presented to the readers.
