The authors’ work started in fermentation in 1977 and in the 1980’s into sugar production and cane quality. Statistical analysis was a key factor for the success of improving yield in ethanol and sugar production as well as cane quality. Adaption of methods for industrial laboratories also was very important in relation to yield and in reduction of sugar losses in the factory. Methodologies to measure sugar losses occurring through degradation in the factory (evaporation) using ion chromatography and dry substance content with a digital density meter were adapted. The fermentation yield improved from 75% in 1977 to 92% in 2014, which was possible by adapting methods for live bacterial counting within 20 min, and by controlling contamination using antimicrobial products through research in the laboratory and the industry. Since 1990 yeasts for industrial fermentation were selected by karyotyping analysis of the nuclear chromosomes and in the last seven years based on mitochondrial DNA. The last technique made the “Process Driven Selection” possible, i.e. one or several yeast strains which fit each distillery. Floc formation in carbonated beverages is not only due to the Indicator Value (discovery by SPRI research group) but also to aconitic acid and calcium under Brazilian conditions.

Valuable Compounds

The use of microbial fuel cells (MFCs) is quickly spreading in the fields of bioenergy generation and wastewater treatment, as well as in the biosynthesis of valuable compounds for microbial electrolysis cells (MECs). MFCs and MECs have not been able to penetrate the market as economic feasibility is lost when their performances are boosted by nanomaterials. The nanoparticles used to realize or decorate the components (electrodes or the membrane) have expensive processing, purification, and raw resource costs. In recent decades, many studies have approached the problem of finding green synthesis routes and cheap sources for the most common nanoparticles employed in MFCs and MECs. These nanoparticles are essentially made of carbon, noble metals, and non-noble metals, together with a few other few doping elements. In this review, the most recent findings regarding the sustainable preparation of nanoparticles, in terms of syntheses and sources, are collected, commented, and proposed for applications in MFC and MEC devices. The use of naturally occurring, recycled, and alternative raw materials for nanoparticle synthesis is showcased in detail here. Several examples of how these naturally derived or sustainable nanoparticles have been employed in microbial devices are also examined. The results demonstrate that this approach is valuable and could represent a solid alternative to the expensive use of commercial nanoparticles.

Integration Strategies

Water hyacinth (WH) is an invasive aquatic macrophyte that dominates freshwater bodies across the world. However, due to its rapid growth rate and wide-spread global presence, WH could offer great potential as a biomass feedstock, including for bioenergy generation. This study compares different integration strategies of hydrothermal carbonisation (HTC) and anaerobic digestion (AD) using WH, across a range of temperatures. These include (i) hydrochar combustion and process water digestion, (ii) hydrochar digestion, (iii) slurry digestion. HTC reactions were conducted at 150 °C, 200 °C, and 250 °C. Separation of hydrochars for combustion and process waters for digestion offers the most energetically-feasible valorisation route. However, hydrochars produced from WH display slagging and fouling tendencies; limiting their use in large-scale combustion. AD of WH slurry produced at 150 °C appears to be energetically-feasible and has the potential to also be a viable integration strategy between HTC and AD, using WH.
