Location of water in fresh sugarcane bagasse observed by synchrotron X-ray microtomography.

Sugarcane bagasse is a vast lignocellulosic byproduct generated in the industry with ~50% humidity (1 kg dry matter associated with 1 kg water). Although the presence of water brings deleterious consequences for combustion, storage and sugar extraction, the location of water in fresh bagasse remains unknown. In this work, we use synchrotron X-ray microtomography for non-invasive 3D imaging of fresh bagasse particles, which allows the visualization of intraparticle water. The sclerified fiber cells in the sh...

Incorporating anaerobic co-digestion of steam exploded or ammonia fiber expansion pretreated sugarcane residues with manure into a sugarcane-based bioenergy-livestock nexus.

The co-digestion of pretreated sugarcane lignocelluloses with dairy cow manure (DCM) as a bioenergy production and waste management strategy, for intensive livestock farms located in sugarcane regions, was investigated.

Stepwise enzymatic hydrolysis of alkaline oxidation treated sugarcane bagasse for the co-production of functional xylo-oligosaccharides and fermentable sugars.

High chemical input is required for enzymatic production of xylo-oligosaccharides (XOS) using xylan extracted from lignocellulosic biomass. In this study, enzymatic hydrolysis of alkaline oxidation (AO) treated sugarcane bagasse (SCB) directly for the production of XOS was conducted. The effect of AO pretreatment on the chemical compositions and hydrolytic properties of SCB was investigated. The AO pretreatment conditions with low chemical input for the production of XOS were optimized by orthogonal design....

Adding value to lignocellulosic wastes via their use for endoxylanase production by Aspergillus fungi.

Agroforestry industries in the world generate lignocellulosic wastes that can be a huge problem of pollution, or the wastes can be used for different biotechonological applications such as substrates for microorganism growth and enzyme production. Fungi such as Aspergillus niger can grow in almost every substrate and produce hydrolytic enzymes such as endoxylanases, giving added value to agroforestry wastes generated by industries in the northeast of Argentina.

Green synthesis of reduced graphene oxide using bagasse and its application in dye removal: A waste-to-resource supply chain.

Graphene is usually synthesized through deoxygenation of graphene oxide (GO) by hydrazine which functions as a reducing agent, but the production of graphene via this method suffers a high cost and is often regarded to be not environmental-friendly. In this work, we developed a simple and efficient method for the green reduction of GO to reduced graphene oxide (rGO) dispersed on sugarcane bagasse derived from rGO/bagasse material. The rGO/bagasse was characterized by Scanning electron microscopy, Fourier tr...

After the isolation, biochemical characterizations were performed, giving a temperature of 50 °C and optimum pH of 5. The enzyme was stable at 39-60 °C for 60 min and at a p...

Poultry biogas slurry can partially substitute for mineral fertilizers in hydroponic lettuce production.

Poultry biogas slurry, a by-product of the biogas production process, is rich in nutrients. However, improper handling increases the potential for serious environmental contamination and resource waste. The preparation of nutrient solutions for hydroponic lettuce production requires large amounts of mineral fertilizers, which provides an opportunity for poultry biogas slurry to enter the crop nutrient cycle. To assess the feasibility of the application of poultry biogas slurry, we used different proportions...

Comparing laboratory and industrial yeast platforms for the direct conversion of cellobiose into ethanol under simulated industrial conditions.

An engineered yeast producing all the cellulases needed for cellulose saccharification could produce ethanol from lignocellulose at a lower cost. This study aimed to express fungal β-glucosidases in Saccharomyces cerevisiae to convert cellobiose into ethanol. Furthermore, two engineering platforms (laboratory vs industrial strain) have been considered towards the successful deployment of the engineered yeast under simulated industrial conditions. The industrial S. cerevisiae M2n strain was engineered throu...

The two datasets outlined in this paper contain information related to (a) the local impacts of biofuel feedstock production, and (b) the factors that influence the adoption and/or sustained use of ethanol stoves in southern Africa. The first dataset was generated through extensive household surveys around four operational jatropha and sugarcane production sites in Malawi, Mozambique, and Swaziland. This project aimed to examine the local impacts of the most prominent modes of existing or intended biofuel f...

Characterization of the Clostridium thermocellum AdhE, NfnAB, Ferredoxin and Pfor proteins for their ability to support high titer ethanol production in Thermoanaerobacterium saccharolyticum.

The thermophilic anaerobes Thermoanaerobacterium saccharolyticum and Clostridium thermocellum are good candidates for lignocellulosic ethanol production. T. saccharolyticum has been successfully engineered to produce ethanol at high titer (70g/L). The maximum ethanol titer of engineered strains of C. thermocellum is only 25g/L. We hypothesize that one or more of the enzymes in the ethanol production pathway in C. thermocellum is not adequate for ethanol production at high titer. In this study, we focused on...

Interaction between the production of ethanol and glycerol in fed-batch bioreactors.

During alcoholic fermentation, most of the substrates supplied to the yeasts are converted into ethanol and carbon dioxide generating energy for cell maintenance. However, some of these substrates end up being diverted to other metabolic pathways generating by-products reducing the yield in ethanol production. Glycerol is the most important by-product quantitatively, and its production during fermentation is associated to the production of ethanol. The present study was carried out at a full scale in an ind...
