Abstract Background Lignocellulosic biomass has long been recognized as a potential sustainable source for industrial applications. The costs associated with conversion of plant biomass to fermentable sugar represent a significant barrier to the production of cost-competitive biochemicals. Consolidated bioprocessing (CBP) is considered a potential breakthrough for achieving cost-efficient production of biomass-based fuels and commodity chemicals. During the degradation of cellulose, cellobiose (major end-product of cellulase activity) is catabolized by hydrolytic and phosphorolytic pathways in cellulolytic organisms. However, the details of the two intracellular cellobiose metabolism pathways in cellulolytic fungi remain to be uncovered. Results Using the engineered malic acid production fungal strain JG207, we demonstrated that the hydrolytic pathway by β-glucosidase and the phosphorolytic pathway by phosphorylase are both used for intracellular cellobiose metabolism in Myceliophthora thermophila, and the yield of malic acid can benefit from the energy advantages of phosphorolytic cleavage. There were obvious differences in regulation of the two cellobiose catabolic pathways depending on whether M. thermophila JG207 was grown on cellobiose or Avicel. Disruption of Mtcpp in strain JG207 led to decreased production of malic acid under cellobiose conditions, while expression levels of all three intracellular β-glucosidase genes were significantly up-regulated to rescue the impairment of the phosphorolytic pathway under Avicel conditions. When the flux of the hydrolytic pathway was reduced, we found that β-glucosidase encoded by bgl1 was the dominant enzyme in the hydrolytic pathway and deletion of bgl1 resulted in significant enhancement of protein secretion but reduction of malate production. Combining comprehensive manipulation of both cellobiose utilization pathways and enhancement of cellobiose uptake by overexpression of a cellobiose transporter, the final strain JG412Δbgl2Δbgl3 produced up to 101.2 g/L and 77.4 g/L malic acid from cellobiose and Avicel, respectively, which corresponded to respective yields of 1.35 g/g and 1.03 g/g, representing significant improvement over the starting strain JG207. Conclusions This is the first report of detailed investigation of intracellular cellobiose catabolism in cellulolytic fungus M. thermophila. These results provide insights that can be applied to industrial fungi for production of biofuels and biochemicals from cellobiose and cellulose.

The Cost

The 1930s was the heyday of the Indonesian sugarindustry that is capable of exporting to manycountries and has become the country an exporterof sugar to two after Cuba, but the situation isreversed since 1967 in which Indonesia wouldimport sugar from Brazil, India, and Thailand inorder to meet the needs raw material consumptionand food and beverage industry. The resultsshowed that the cost of sugar production isvery uneconomical because of inefficiency thatstretches from the cultivation to processing inthe factory so difficult to obtain profit margins.Target and beyond sugar self-sufficiency can notbe achieved because highly regulated, there is nosynergy and tends to conflicts of interests amongministries or agencies, and internal conflicts oftenoccur between the sugar mill and the disharmonybetween sugarcane farmers by the sugar millofficials.In the competition of the sugar industry aremore stringent, in the era of the Asean EconomicCommunity, it means the level of efficiency of sugarfactories in the country need special attention,the same thing also applies to industrial users ofsugar, and sugar as a raw material componentscontribute to the creation of products food andbeverage efficient so as to compete with similarproducts from other countries. Observing howthe intense competition in the Asean EconomicCommunity is based on free trade, the yield ofsugar that’s a cost efficient production is veryimportant and urgent at this time, including workto improve the welfare of farmers.

Advances in nucleic acid sequencing technologies have revolutionized the field of genomics, allowing the efficient targeting of mutated neoantigens for personalized cancer vaccination. Due to their absence during negative selection of T cells and their lack of expression in healthy tissue, tumor mutations are considered as optimal targets for cancer immunotherapy. Preclinical and early clinical data suggest that synthetic mRNA can serve as potent drug format allowing the cost efficient production of highly efficient vaccines in a timely manner. In this review, we describe a process, which integrates next generation sequencing based cancer mutanome mapping,in silicotarget selection and prioritization approaches, and mRNA vaccine manufacturing and delivery into a process we refer to as MERIT (mutanome engineered RNA immunotherapy).

In today’s rapidly changing demands of commercial buildings, designers, manufacturers, contractors, and installers face the necessity to advance their methods, to improve techniques, and generally to stay competitive under all constraints of time, budget, codes and client desires. Building with precast concrete elements provides quick and cost-efficient production, along with flexible, independent interior design. The show-window of the investigated commercial building is divided into several glass panels. Having only upper and lower grip, the glass window panels with very tall heights, are subject to deformation. In order to resist, panels are provided with U-shaped profiles or/ and perimeter rails. The critical points are the glass panels’ support, so the ceiling and floor fastenings have to be very solid, as well as qualitatively superior designed and executed. This paper aims to highlight some relevant aspects regarding the investigation of the metal fixing system designed to connect show-window panels to prestressed concrete ceiling beams at a commercial building.

Renewable Energy Storage

There is a need to address the gap between the theoretical benefits and cost-efficient production of supercapacitors in the market in order to sway the preference of the industry from the current perishable energy sources and storage. More extensive exploration of sustainable fabrication methods and materials used for renewable energy storage are just some of the factors that would decrease this gap. A binder-free supercapacitor electrode made of NiCo2O4 and carbonized kapok fiber paper (CKFP) was successfully fabricated by hydrothermal process at relatively low temperatures. NiCo2O4 urchin-like structures were deposited on the surface of carbon fiber paper (CFP) and CKFP. XRD analysis confirmed the successful conversion of kapok fiber paper to CKFP after pyrolysis, as well as the growth of pure spinel NiCo2O4 nanostructures on CFP and CKFP. The cyclic voltammetry curves showed that the CFP-NiCo2O4 prepared at 140 °C had the highest specific capacitance of 143.51 Fg-1 at 2 mVs-1. The CKFP-NiCo2O4 synthesized at the same temperature yielded slightly higher specific capacitance of 146.29 Fg-1 at 2 mVs-1, and 508 Fg-1 at 0.5 Ag-1.

A thermal model for laser-assisted cutting of mullite is developed in this paper. Laser-assisted cutting has been proposed as a promising means for achieving cost-efficient production of high quality ceramic parts. At high temperatures the yield strength of ceramics can decrease below the fracture strength, changing the material deformation behavior from brittle to ductile and enabling the use of a single point cutting tool to remove material at rates approaching those of metal cutting. Assuming the system to be symmetrical and neglecting the heat loss taken away by removal material, the problem is formulated in a cylindrical coordinate system that moves with the laser beam or cutting tool. An analytical solution for this thermal model is obtained. The results calculated by this model agree with the available experimental data. The temperature history is presented during laser-assisted cutting of mullite. The effects of feed rate and laser power on temperature history are also discussed in this study.

Equal Channel Angular Swaging (ECAS) is a new severe plastic deformation process which combines the conventional equal channel angular pressing (ECAP) and the incremental bulk forming process rotary swaging. The tool system consists of two rotary swaging dies with an angled channel that contains four shear zones, generating severe plastic strain per pass. The crucial advantages compared to conventional ECAP are a significant reduction of friction and axial forces plus the potential to be extended to continuous processing. Thus, ECAS has high potential for a cost-efficient production of bulk UFG materials. In the present paper the principles of ECAS are introduced and first experimental results for the processing of copper are presented.

The electrification of drives is an enormous challenge as well as an opportunity for the automobile industry and its suppliers to provide competitive and affordable technologies to participate within this change. The high costs of battery systems, the range limitations of electric vehicles and the insufficient charging network are three of the main reasons, this change is still troublesome in its realization. To realize a cost-efficient production of battery systems, a high degree of automation and an increased production throughput is necessary. This paper focuses on the pouch cell with its high energy density and presents a solution, of how to significantly increase the production throughput in the z-folding of separators. The approach pursued is the assessment of shifting from discrete pick-and-place operations to a continuous process flow, enabling a cost-efficient production of electrode-separator compounds and ultimately lithium-ion batteries.
