Environmental pollution is a worldwide concern now. A major section of the world population is struggling for drinking water. Polluted soil is resulting into low agricultural productivity and thus creating challenges in the way of sustainable livelihood of a large section of human population. Biological treatment can offer both green solutions for wastewater treatment and resource recovery as well. Like algal-based systems can be utilized for wastewater treatment and production of biofuels from the biomass grown on the wastewater. Bio-based nanomaterials have been extensively studied for their employability in the health care, process optimization, water resource management, dealing with environmental pollutants, biosensors, and many others. Bioprospecting of novel biological agents, bio-based products, and bioresource recovery are paving the way for sustainable development as they are providing local solutions for a number of problems.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 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.

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.

This book explains the main problems of industrial wastewater treatments and how they are being treated by innovative biological processes. The need for clean water in developing countries has become difficult to achieve as a result of globalization and industrialization and  because of an increase in population, urbanization, and per capita water use.Residential, commercial, industrial, and educational institutions produce immense amounts of wastewater.  Wastewater is treated to extract toxins to produce processed effluent by physical, chemical, and biological processes. Most of these innovative treatment systems are membrane filtration, advanced oxidation processes, and electrochemical approaches, which are strongly committed to offering solutions to help protect public health and the environment.For wastewater treatment, different forms of bioreactors are used which are reliable, cost-efficient, and effective in removing a wide variety of contaminants.This book outlines the capacity of various bioreactors that are most widely used for the treatment of different industrial and domestic wastewater, such as a rotating biological contactor, biological fluidized bed reactor, packed bed reactor, membrane bioreactor, continuous stirred tank bioreactor, up-flow anaerobic sludge blanket reactor, and photobioreactor, etc.Despite this, the acceptance of these technologies and their commercialization on an industrial scale, the performance is still limited. Therefore, a broader use of cost-effective in situ remedial approaches to natural phenomena like bioremediation is needed. The role of numerous bioreactors in industrial effluent treatment has, including recent developments, also been explored in depth. Furthermore, it includes the operational factors affecting their performances, advances in their architectural design, their amalgamation with the existing setup, scale-up studies, life cycle assessment of those reactors, materials and cost analysis, etc. This information helps the reader to understand the insight into the mechanism, pros and cons, moreover efficient utilization, and commissioning of bioreactors.

This book provides insights into current developments and the revolution in industrial applications of miniaturized bioreactors. Miniaturized bioreactors transform industrial biotechnology by facilitating quick, efficient, and cost-effective development. These small-scale bioreactors enable high-throughput screening of many conditions simultaneously, speeding up the tuning of critical parameters such as temperature, pH, and nutrition delivery. This results in higher product yields, better quality, and faster bioprocess scale-up. Miniaturization also saves vital resources and lessens the environmental impact of bioproduction. By providing a diverse platform for bioprocess development, miniaturized bioreactors can potentially accelerate biotechnology innovation and sustainability. The book further discusses the role of miniature bioreactors in microbial screening, high-throughput cellular screening, the revolutionizing of upstream and downstream processing systems along with numerous potential applications. The subsequent sections describe the uses of miniaturized bioreactors across industrial biotechnology, including biopharmaceuticals, drug development, small- and large-scale industries, and the food and beverage sectors.
