“…Nevertheless, basic studies on the availability of biomass derived compounds to microorganisms are urgently required in order to assess processes regarding productivities and yields. While starchy materials are easily available to microorganism, lignocellulosic materials are not and require pretreatment and hydrolysis (Pleissner and Venus, 2014). Pretreatment and hydrolysis are often carried out at high temperatures in presence of acids and mostly followed by an enzymatic treatment to improve the release of monosugars, such as glucose and xylose.…”

In this study, the lignocellulosic residue coffee pulp was used as carbon source in fermentative l(+)-lactic acid production using Bacillus coagulans. After thermo-chemical treatment at 121°C for 30min in presence of 0.18molL(-1) H2SO4 and following an enzymatic digestion using Accellerase 1500 carbon-rich hydrolysates were obtained. Two different coffee pulp materials with comparable biomass composition were used, but sugar concentrations in hydrolysates showed variations. The primary sugars were (gL(-1)) glucose (20-30), xylose (15-25), sucrose (5-11) and arabinose (0.7-10). Fermentations were carried out at laboratory (2L) and pilot (50L) scales in presence of 10gL(-1) yeast extract. At pilot scale carbon utilization and lactic acid yield per gram of sugar consumed were 94.65% and 0.78gg(-1), respectively. The productivity was 4.02gL(-1)h(-1). Downstream processing resulted in a pure formulation containing 937gL(-1)l(+)-lactic acid with an optical purity of 99.7%.

“…Lactic acid from coffee residues has been produced earlier in mixed-acid fermentation (Woiciechowski et al, 1999). However, we used the thermophilic bacterium Bacillus coagulans, which was shown to efficiently convert sugars from hydrolyzed agricultural residues into only L(+)-lactic acid (Pleissner and Venus, 2014).…”

“…Furthermore, the evolved strain produced 87.9 g/L of SA from food waste hydrolysate with 85% theoretical yield, which is the highest SA yield in yeast to date (Figure ). This suggests that this evolved strain has a high potential for SA fermentation using glucose-rich agricultural residues and food waste derived feedstocks since there are around 3.7 billion tons of agricultural residues worldwide, with a composition of about 40% cellulose. , The annual global production of food wastes is 1.3 billion tons, and these food wastes contain around 30–60% of starch. , These agricultural- and food residues could potentially be hydrolyzed as glucose-rich nutrient source that represents a promising feedstock in biotechnological processes. ,, Very recently, a study of this evolved yeast strain was carried out in a novel mixed fruit and vegetable waste biorefinery concept in SA fermentation by our group (Li et al) . Moreover, to decrease the cost of downstream processing, the evolutionary approach in this study would be used for enhanced SA production in low pH environment using Y. lipolytica .…”

Succinate dehydrogenase inactivation in Yarrowia lipolytica has been demonstrated for robust succinic acid production, whereas the inefficient glucose metabolism has hindered its practical application. In this study, a simple and efficient adaptive evolution strategy via cell immobilization was conducted in shake flasks, with an aim to restore the glucose metabolism of Y. lipolytica mutant PGC01003. After 21 days with 14 generations evolution, glucose consumption rate increased to 0.30 g/L/h in YPD medium consisting of 150 g/L initial glucose concentration, while poor yeast growth was observed in the same medium using the initial strain without adaptive evolution. Succinic acid productivity of the evolved strain also increased by 2.3-fold, with stable cell growth in YPD medium with high initial glucose concentration. Batch fermentations resulted in final succinic acid concentrations of 65.7 g/L and 87.9 g/L succinic acid using YPD medium and food waste hydrolysate, respectively. The experimental results in this study show that a simple and efficient strategy could facilitate the glucose uptake rate in succinic acid fermentation using glucose-rich substrates.

The aim of this paper is to calculate the amount of energy or chemicals that can be produced using anaerobic digestion (AD). Five feedstocks were considered: the organic fraction of municipal solid waste (OFMSW); cattle, pig and poultry manure; energy crops; agricultural residues, and sewage sludge. Carbohydrates, proteins, and lipids were assumed to be the biodegradable components of the feedstocks. Chemical oxygen demand (COD) was assumed as a basis for the calculations of the production of methane and other chemicals. Methane production was calculated assuming that AD converts the biodegradable COD to methane with a yield of 80% COD/COD. The potential production of chemicals, i.e. acetic, propionic, butyric, and lactic acids, ethanol, and hydrogen, was calculated assuming conversion yields of carbohydrates, proteins, and lipids from the literature. Globally, with the assumptions made in this study, the AD of the feedstocks considered here can potentially satisfy 17–20% of the total energy consumption and 33–39% of the electrical energy requirements. Potentially, AD can generate organic acids at rates that are hundreds or thousands of times their current production rates. Ethanol and hydrogen can be produced by AD at rates that are up to 2–3 times their current production rate. This paper also discusses the main challenges that must be overcome to achieve the potential of AD. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd
