Abstract

International audience; Crop losses from pests threaten global food security and safety. In the last six decades, pest control using chemical pesticides has resulted in important yield gains per unit area, worldwide. However, the long-term sustainability of chemical pest control has been increasingly thrown into doubt due to the negative impact on human health, biodiversity, and the environment. Consequently, there is an urgent need to improve the science of crop protection in order to tackle the five key challenges of 21st century agriculture holistically: (i) maintaining or improving agricultural productivity, (ii) producing healthy food, (iii) reducing the negative impacts of agriculture on ecosystem and human health, (iv) ensuring the economic viability of farms, and (v) adapting agriculture to climate change. Agroecological Crop Protection (ACP) can be a powerful approach to address these challenges, as we demonstrate in this paper. ACP is the application of the principles of agroecology to crop protection in order to promote virtuous and sustainable changes in agriculture and food systems. ACP combines multiple approaches and disciplines including ecology, agroecology, and Integrated Pest Management. It promotes a crop protection system compatible with healthy agricultural and food systems, agroecological principles and the “one health” approach. We predict that ACP will meet the challenge of pesticide-free agriculture in the future. In this paper, we will first present the scientific, agricultural and social components of ACP. We will then analyze the research approaches, questions, methods and tools needed to adopt ACP. Finally, we suggest key mechanisms to facilitate the transition to ACP, which will ultimately provide sustainable food, feed, and fuel in a context of major global change.

Abstract

Clostridium acetobutylicum has received renewed interest worldwide as a promising producer of biofuels and bulk chemicals such as n-butanol, 1,3-propanediol, 1,3-butanediol, isopropanol, and butyrate. To develop commercial processes for the production of bulk chemicals via a metabolic engineering approach it is necessary to better characterize both the primary metabolism and metabolic regulation of C. acetobutylicum. Here, we review the history of the development of omics studies of C. acetobutylicum, summarize the recent application of quantitative/integrated omics approaches to the physiological analysis and metabolic engineering of this bacterium, and provide directions for future studies to address current challenges.

Abstract

Background: Clostridium acetobutylicum and Clostridium saccharobutylicum are Gram-positive, spore-forming, anaerobic bacterium capable of converting various sugars and polysaccharides into solvents (acetone, butanol, and ethanol). The sequencing of their genomes has prompted new approaches to genetic analysis, functional genomics, and metabolic engineering to develop industrial strains for the production of biofuels and bulk chemicals.Results: The method used in this paper to knock-out, knock-in, or edit genes in C. acetobutylicum and C. saccharobutylicum combines an improved electroporation method with the use of (i) restrictionless Δupp (which encodes uracil phosphoribosyl-transferase) strains and (ii) very small suicide vectors containing a markerless deletion/insertion cassette, an antibiotic resistance gene (for the selection of the first crossing-over) and upp (from C. acetobutylicum) for subsequent use as a counterselectable marker with the aid of 5-fluorouracil (5-FU) to promote the second crossing-over. This method was successfully used to both delete genes and edit genes in both C. acetobutylicum and C. saccharobutylicum. Among the edited genes, a mutation in the spo0A gene that abolished solvent formation in C. acetobutylicum was introduced in C. saccharobutylicum and shown to produce the same effect.Conclusions: The method described in this study will be useful for functional genomic studies and for the development of industrial strains for the production of biofuels and bulk chemicals.

Abstract

Developing a commercial process for the biological production of n-butanol is challenging as it needs to combine high titer, yield, and productivities. Here we engineer Clostridium acetobutylicum to stably and continuously produce n-butanol on a mineral media with glucose as sole carbon source. We further design a continuous process for fermentation of high concentration glucose syrup using in situ extraction of alcohols by distillation under low pressure and high cell density cultures to increase the titer, yield, and productivity of n-butanol production to the level of 550 g/L, 0.35 g/g, and 14 g/L/hr, respectively. This process provides a mean to produce n-butanol at performance levels comparable to that of corn wet milling ethanol plants using yeast as a biocatalyst. It may hold the potential to be scaled-up at pilot and industrial levels for the commercial production of n-butanol., Organic solvent n-butanol is produced mainly by petrochemical method. Here, the authors revive the historical Weizmann process by engineering Clostridium acetobutylicum strain and developing low pressure distillation and high cell density cultures for n-butanol continuous production at high-yield titer and productivity.

Abstract

Two-way relay analog network coding improves the communication rate of a network with symmetric traffic between two end nodes by combining different transmission flows and exploiting the fact that the self-interference can be cancelled at each node. However, this scheme does not efficiently work in the case of asymmetric traffic between the nodes. We propose a novel scheme for a multi-cell multi-user shared-relay network with asymmetric traffic. By exploiting the overheard signals from the users with uplink messages to the users with downlink messages, we determine the precoding matrices at the base stations and the relay station, and use interference alignment such that all interference signal is suppressed. Numerical results show that the new scheme's performance is better than a corresponding benchmark scheme in terms of sum-rate and user rates.

Abstract

International audience; Software testing plays an important role in verifying and assessing the quality of a software application. There are various testing approaches proposed for different application scenarios. In this paper, we propose a new passive testing approach to verifying a timed trace with respect to a set of constraints. With the extension of Nomad language, we are able to formally describe all constraints and combine conditions by logical operations AND and OR into expressions. By well organizing and evaluating the expressions, we are able to carry out runtime verification message by message in a timed trace. In addition to the theoretical framework, we have also developed a software tool known as RV4WS (Runtime Verification for Web Services) for the automation of our testing approach, and implemented all algorithms in the paper with this tool. We conduct a case study of web service composition to verify the effectiveness of our approach and tool.
