“…Biofuel production has grown significantly worldwide and is seen as one of the main alternatives to convert the planet’s climate crisis and greenhouse gas emissions [ 12 ]. As they do not compete with food crops, second-generation biofuels are seen as a more sustainable and efficient alternative when compared to first-generation ones [ 296 ].…”

“…In that regard, biotechnology emerges as a tool capable of increasing food security and productivity by occupying less area. In addition, it reduces greenhouse gas emissions through more sustainable technologies for energy and food production, biofuel production, and bioremediation, among others [ 7 , 8 , 9 , 10 , 11 , 12 ]. This way, biotechnology is considered a meaningful way to revert the current environmental crisis scenario [ 13 , 14 ].…”

Human population growth, industrialization, and globalization have caused several pressures on the planet’s natural resources, culminating in the severe climate and environmental crisis which we are facing. Aiming to remedy and mitigate the impact of human activities on the environment, the use of lignocellulolytic enzymes for biofuel production, food, bioremediation, and other various industries, is presented as a more sustainable alternative. These enzymes are characterized as a group of enzymes capable of breaking down lignocellulosic biomass into its different monomer units, making it accessible for bioconversion into various products and applications in the most diverse industries. Among all the organisms that produce lignocellulolytic enzymes, microorganisms are seen as the primary sources for obtaining them. Therefore, this review proposes to discuss the fundamental aspects of the enzymes forming lignocellulolytic systems and the main microorganisms used to obtain them. In addition, different possible industrial applications for these enzymes will be discussed, as well as information about their production modes and considerations about recent advances and future perspectives in research in pursuit of expanding lignocellulolytic enzyme uses at an industrial scale.

“…Their complex digestive systems, including mastication, allow them to consume a variety of low-value wastes, including municipal organic waste 16 and livestock manure 17 . Crude waste can be fed directly to insects without pre-processing, refinement, and sterilization necessary for microbial fermentation 18,19 . Some insect species, such as Black soldier flies ( Hermetia illucens ), which are already used to manage waste have excellent tolerance to bacteria and fungi 20 and are easily separated from the organic waste for downstream processing 21 .…”

Inadequate management of household and industrial wastes pose major challenges to human and environmental health. Advances in synthetic biology may help address these challenges by engineering biological systems to perform new functions such as biomanufacturing of high-value compounds from low-value waste streams and bioremediation of industrial pollutants. However, the current emphasis on microbial systems for biomanufacturing, which often require highly pre-processed inputs and sophisticated infrastructure, is not feasible for many waste streams. Meanwhile, concerns about transgene biocontainment have limited the release of engineered microbes or plants for bioremediation. Engineering animals may provide opportunities for utilizing various waste streams that are not suitable for microbial biomanufacturing while effective transgene biocontainment options should enable in situ bioremediation. Here, we engineer the model insect Drosophila melanogaster to express a functional laccase from the fungus Trametes trogii. Laccase expressing flies reduced bisphenol A by more than 50% when present in their growth media, while a lyophilized powder made from engineered adult flies degraded more than 90% of bisphenol A and indigo carmine in aqueous solutions. Our results demonstrate that transgenic animals may be used to bioremediate environmental contaminants in vivo and serve as novel production platforms for industrial enzymes. These results support further development of insects, and possibly other animals, as bioproduction platforms and their potential use in bioremediation.

In the past few years, biofuels have emerged as renewable alternative to encounter global energy requirements in a greener way. Biomass is a sustainable cost-effective natural resource with wide diversity for conversion to biofuel such as biodiesel, biogas, bio-oil, biohydrogen, etc. via various chemical, thermal, or biochemical routes. Catalysis plays a pivotal role to convert biomass to biofuels, but conventional catalysts show a lot of short comings. To address these problems, a novel nanocatalysts approach is considered to be the most promising option. Nanocatalysts offer extremely high surface area, enhanced selectivity, better stability and cataly-tic activity at an atomic and molecular level in comparison to bulk catalysis. Here an insight about the limitation of traditional catalysts, the importance of nanocatalysts, various types of nanocatalysts, and their application in conversion of biomass to biofuel is given. It emphasizes the state-of-the-art developments in terms of catalysis and catalytic processes that are anticipated to play a crucial role in biomass conversion to fuel are emphasized and the chemistry behind nanocatalyst design for biofuel production and reduction of inhibitory effect is highlighted.
