The diversity of agro industrial wastes makes them an attractive group of organic wastes for potential use in a wide variety of industrial and biotechnological applications. The new stimulating development in this current area of research approaches in combination with the technologies of large-scale production and biotechnology engineering, agro industrial wastes will be economically successful materials of the future. Increased public awareness of issues related to hydrocarbon pollution strongly influences the development of technologies that speed up cleaning hazardous contaminants. The cost of biodegradation technology and the low bioavailability including mass transfer limitations of hydrocarbons, especially those recalcitrant components, from various mediums into the aqueous phase for effective enzyme-based microbial biodegradation still constitute major challenges. Sustainable replacement of traditional microbiological media with agroindustrial wastes as substrates for biosurfactant production holds great potential; thereby decrease numerous management problems of handling industrial waste. These organic nitrogen-rich nutrients (biostimulation) are an effective means to enhance the bioremediation process and widely available as wastes in the environment; hence, they can serve as “natural waste-to-environmental clean-up.” However, current chapter have focused on the combined use of biosurfactants and enzymes produced from renewable resources such as agro-industrial waste, through assisted biostimulation and bioaugmentation, for hydrocarbon biodegradation.

A novel nanomaterial, bacterial cellulose (BC), has become noteworthy recently due to its better physicochemical properties and biodegradability, which are desirable for various applications. Since cost is a significant limitation in the production of cellulose, current efforts are focused on the use of industrial waste as a cost-effective substrate for the synthesis of BC or microbial cellulose. The utilization of industrial wastes and byproduct streams as fermentation media could improve the cost-competitiveness of BC production. This paper examines the feasibility of using typical wastes generated by industry sectors as sources of nutrients (carbon and nitrogen) for the commercial-scale production of BC. Numerous preliminary findings in the literature data have revealed the potential to yield a high concentration of BC from various industrial wastes. These findings indicated the need to optimize culture conditions, aiming for improved large-scale production of BC from waste streams.

Lactic acid (LA) is an organic compound used in several industries, such as food, textile, chemical, and pharmaceutical. The global interest  in  this  product  is  due  to  its  use  for  the  synthesis  of  numerous  chemical  compounds,  including  polylactic  acid,  a  biode-gradable thermoplastic and substitute for petroleum-derived plastics. An in-depth overview of the use of industrial and household wastes as inexpensive substrates in order to reduce the cost of LA production is presented. A review is carried out of the biotech-nological aspects that must be taken into account when using some wastes with high transformation potential to produce LA in a submerged  culture,  as  well  recommendations  for  their  use.  The  advantages  and  disadvantages  of  different  types  of  treatments used for the transformation of waste into suitable substrates are considered. Several methods of fermentation, as well as genetic strategies for increasing the production, are summarized and compared. It is expected that in a few years there will be many ad-vances in these areas that will allow greater large-scale production of LA using agroindustrial or household wastes, with potential positive economic and environmental impact in some regions of the planet.

Looking at the history of solar energy and renewable energy in general, the authorities and scientists have been paying much attention to the recent period, due to the depletion of fossil energy resources and the growing difficulties in solving environmental problems. The development of solar energy has led to the use of solar energy concentrators. Concentrators are used to concentrate sunlight onto PV cells. This allows for a reduction in the cell area required for producing a given amount of power. The goal is to significantly reduce the cost of electricity generated by replacing expensive PV converter area with less expensive optical material. In this chapter, the authors talk about concentrators in solar energy, especially about modules based on holographic films. Holographic solar panels (HSP) in recent decades have appeared in large-scale production and been actively used in solar energy. Evaluations of other types of existing concentrators are presented.

The alarming escalation of infectious diseases resistant to conventional antibiotics requires urgent global actions, including the development of new therapeutics. Antimicrobial peptides (AMPs) represent potential alternatives in the treatment of multi-drug resistant (MDR) infections. Here, we focus on Cecropins (Cecs), a group of naturally occurring AMPs in insects, and on synthetic Cec-analogs. We describe their action mechanisms and antimicrobial activity against MDR bacteria and other pathogens. We report several data suggesting that Cec and Cec-analog peptides are promising antibacterial therapeutic candidates, including their low toxicity against mammalian cells, and anti-inflammatory activity. We highlight limitations linked to the use of peptides as therapeutics and discuss methods overcoming these constraints, particularly regarding the introduction of nanotechnologies. New formulations based on natural Cecs would allow the development of drugs active against Gram-negative bacteria, and those based on Cec-analogs would give rise to therapeutics effective against both Gram-positive and Gram-negative pathogens. Cecs and Cec-analogs might be also employed to coat biomaterials for medical devices as an approach to prevent biomaterial-associated infections. The cost of large-scale production is discussed in comparison with the economic and social burden resulting from the progressive diffusion of MDR infectious diseases.

In this paper we examine the issue of optimizing disk usage and scheduling large-scale scientific workflows onto distributed resources where the workflows are data-intensive, requiring large amounts of data storage, and the resources have limited storage resources. Our approach is two-fold: we minimize the amount of space a workflow requires during execution by removing data files at runtime when they are no longer needed and we demonstrate that workflows may have to be restructured to reduce the overall data footprint of the workflow. We show the results of our data management and workflow restructuring solutions using a Laser Interferometer Gravitational-Wave Observatory (LIGO) application and an astronomy application, Montage, running on a large-scale production grid-the Open Science Grid. We show that although reducing the data footprint of Montage by 48% can be achieved with dynamic data cleanup techniques, LIGO Scientific Collaboration workflows require additional restructuring to achieve a 56% reduction in data space usage. We also examine the cost of the workflow restructuring in terms of the application's runtime.

Fanout Wafer Level Packaging (FoWLP) is a very attractive solution for microelectronics applications requiring optimized performance, smaller form factor, and low cost. By utilizing such an approach where system integration is done to multiple chips on a single package frame, the need to ensure much higher levels of process integrity, quality, and reliability becomes absolutely critical, especially if the total product volume lies in the range of tens of millions of units. A single defect type may negate the benefits of such an approach because the cost of losing one FoWLP unit results in the loss of multiple devices. Thus, yield, quality, and reliability optimization using such a package solution is critical for successful large scale manufacturing. In this talk, the issue of defectivity and its impact on quality and reliability on Wafer-Level (WL) devices with regards to the issue of Die Edge Delamination (DED) and Chip Mechanical Integrity (CMI) is discussed. Through this discussion and the resulting solutions found to improve WL quality and reliability, better understanding on how to assess the quality and reliability of a given FoWLP solution for large scale production will be demonstrated.

: Aliphatic secondary and tertiary amines are widely used in the production of pharmaceuticals, agrochemicals, dyes, surfactants and rubber chemicals. Most traditional synthetic methods are often unsuitable for large-scale production due to poor selectivity, harsh reaction conditions and the cost of starting materials. In this context, hydroaminomethylation (HAM) is a very attractive catalytic process with high atom economy that starts from inexpensive reagents, such as alkenes. This review aims to provide an updated overview of hydroaminomethylation as a useful tool for synthesizing aliphatic secondary and tertiary amines. Therefore, the discussion will focus on both unsaturated starting compounds and the amines obtained by this one-pot reaction.

Mrs Broth

At present, De Man, Rogosa and Sharpe (MRS) broth is the medium of choice for promoting bacteriocin production. However, this medium is expensive and not applicable for large-scale production. Therefore, a low-cost and high-efficiency culture medium for bacteriocin Lac-B23 production by Lactobacillus plantarum J23 was developed. First, the effects of the composition of MRS broth on bacteriocin Lac-B23 production and bacterial growth were researched by a one variable at a time approach. Then, a Plackett-Burman design was used to screen significant components for production. Finally, the steepest ascent and central composite designs were used to obtain an optimum medium. The final composition of the modified MRS was much simpler than MRS broth, and the modified MRS contained only glucose, yeast extract, dipotassium phosphate, manganese sulfate monohydrate, Tween 80 and sodium acetate anhydrous. The highest bacteriocin Lac-B23 production reached 2560 activity units (AU)/mL in the modified MRS, which is nine times higher than that in MRS broth (280 AU/mL). Meanwhile, the cost per liter of the modified MRS (8.56 Ren Min Bi (RMB)/L) is 34.70% the cost of MRS broth (13.11 RMB/L), and the cost per arbitrary units of bacteriocin Lac-B23 in the modified MRS is approximately fourteen times more convenient (3.34 RMB/106 AU) than in the MRS broth (46.82 RMB/106 AU).
