“…Fermentation of FW would not require any nutrient supplements or pretreatment and hydrolysis reactors. It will also not require starch hydrolytic enzymes because the strain used degrades starch [32]. A process schematic for the processing of FW to butanol is presented in Figure 2.…”

Worldwide, there are various feedstocks such as straws, corn stover, sugarcane bagasse, sweet sorghum bagasse (SSB), grasses, leaves, whey permeate, household organic waste, and food waste (FW) that can be converted to valuable biofuels such as butanol. For the present studies, an economic analysis was performed to compare butanol production from three feedstocks (SSB; FW; and yellow top presscake, YTP or YT) using a standard process and an advanced integrated process design. The total plant capacity was set at 170,000–171,000 metric tons of total acetone butanol ethanol (ABE) per year (99,300 tons of just butanol per year). Butanol production from SSB typically requires pretreatment, separate hydrolysis, fermentation, and product recovery (SHFR). An advanced process was developed in which the last three steps were combined into a single unit operation for simultaneous saccharification, fermentation, and recovery (SSFR). For the SHFR and SSFR plants, the total capital investments were estimated as $213.72 × 106 and $198.16 × 106, respectively. It was further estimated that the minimum butanol selling price (using SSB as a feedstock) for the two processes were $1.14/kg and $1.05/kg. Therefore, SSFR lowered the production cost markedly compared to that of the base case. Butanol made using FW had an estimated minimum selling price of only $0.42/kg. This low selling price is because the FW to butanol process does not require pretreatment, hydrolysis, and cellulolytic enzymes. For this plant, the total capital investment was projected to be $107.26 × 106. The butanol selling price using YTP as a feedstock was at $0.73/kg and $0.79/kg with total capital investments for SSFR and SHFR of $122.58 × 106 and $132.21 × 106, respectively. In the Results and Discussion section, the availability of different feedstocks in various countries such as Brazil, the European Union, New Zealand, Denmark, and the United States are discussed. Additionally, the use of various microbial strains and product recovery technologies are also discussed.

El butanol es un biocombustible alternativo al etanol con más alto rendimiento energético y menos corrosivo. La principal ventaja de la producción biológica de butanol es la capacidad de fermentar tanto hexosas como pentosas, lo que lo hace una ruta atractiva para la valorización de residuos biomásicos. No obstante, esta fermentación en procesos convencionales tiene una baja productividad y concentración de producto, es decir, tiene una elevada inversión de capital y requerimientos de energía. Por tal motivo, en esta revisión se analizan las ventajas y desventajas de las diferentes tecnologías alternativas para la producción biológica de butanol. Entre las posibles tecnologías, se estudió la fermentación en etapas usando dos tipos diferentes de microrganismos, sistemas de recuperación in situ, sistemas con recirculación de biomasa e inmovilización celular. Una sola tecnología por sí sola no es capaz de solventar los bajos coeficientes de desempeño de la fermentación. Por lo cual, solo a través de diseños que combinen estas tecnologías se será capaz de volver la producción biológica de butanol grande otra vez. Entre las posibles combinaciones para valorizar los residuos lignocelulósicos, sistemas integrados con evaporación a vacío o con sistemas extractivos con solventes, con producción previa de ácido láctico y recirculación de biomasa, son interesantes ya que permiten alcanzar rendimientos cercanos al teórico, pueden incrementar la productividad en más de dos veces y tiene requerimientos de energía relativamente bajos (7-8 MJ/kg).

“…The microbial strains such as Clostridium beijerinckii , C. acetobutylicum , or C. saccharobutylicum can produce enzymes that hydrolyze disaccharide sugars (sucrose and lactose) into monomeric sugars followed by fermentation to butanol. These strains can also produce butanol from potatoes and starchy grains such as corn in a three step process (corn milling, fermentation, and recovery). They (microbial strains) can produce amylase enzymes that breakdown starch to glucose during fermentation.…”

In these studies, we pretreated sweet sorghum bagasse (SSB) using liquid hot water (LHW) or dilute H SO (2 g L ) at 190°C for zero min (as soon as temperature reached 190°C, cooling was started) to reduce generation of sugar degradation fermentation inhibiting products such as furfural and hydroxymethyl furfural (HMF). The solids loading were 250-300 g L . This was followed by enzymatic hydrolysis. After hydrolysis, 89.0 g L sugars, 7.60 g L acetic acid, 0.33 g L furfural, and 0.07 g L HMF were released. This pretreatment and hydrolysis resulted in the release of 57.9% sugars. This was followed by second hydrolysis of the fibrous biomass which resulted in the release of 43.64 g L additional sugars, 2.40 g L acetic acid, zero g L furfural, and zero g L HMF. In both the hydrolyzates, 86.3% sugars present in SSB were released. Fermentation of the hydrolyzate I resulted in poor acetone-butanol-ethanol (ABE) fermentation. However, fermentation of the hydrolyzate II was successful and produced 13.43 g L ABE of which butanol was the main product. Use of 2 g L H SO as a pretreatment medium followed by enzymatic hydrolysis resulted in the release of 100.6-93.8% (w/w) sugars from 250 to 300 g L SSB, respectively. LHW or dilute H SO were used to economize production of cellulosic sugars from SSB. © 2018 American Institute of Chemical Engineers Biotechnol. Prog., 34:960-966, 2018.
