Living standards and inequality in the industrial revolution: Evidence from the height of University of Edinburgh students in the 1830s

Trends in living standards during the Industrial Revolution is a core debate in economic history. Studies using anthropometric records from institutional sources have found downward trends in living standards during the first half of the nineteenth century. This paper contributes to this literature by utilising an overlooked source of middle and upper class anthropometric data: the height and weight of university students. Combined with more traditional anthropometric sources these data give us a snapshot into the range of living standards experienced by different sections of society in the United Kingdom. Our findings suggest that inequality was most pronounced in Ireland, followed by England. Height inequality in Scotland was still substantial, but somewhat lower in comparison.     

Future societal issues in industrial biotechnology

Three international stakeholder meetings were organized by The Netherlands-based "Kluyver Center for Genomics of Industrial Fermentation" with the objective to identify the future societal issues in the field of industrial biotechnology and to develop a coordinated strategy for public dialogue. The meetings resulted in five unanimous recommendations: (i) that science, industry and the European Commission in conjunction with other stakeholders create a comprehensive roadmap towards a bio-based economy; (ii) that the European Commission initiate a series of round-table meetings to further articulate the views, interests and responsibilities of the relevant stakeholders and to define policy; (iii) that the development of new innovative communication activities is stimulated to increase public engagement and to discuss the ways that we do or do not want technologies to shape our common future; (iv) that further social studies are undertaken on public attitudes and behaviors to the bio-based economy and that novel methods are developed to assess public views of future technological developments; and (v) that the concept of sustainability is further operationalized and taken as a core value driving research and development and policy making.     

Recent advances in plasmid-based tools for establishing novel microbial chassis

A key challenge for domesticating alternative cultivable microorganisms with biotechnological potential lies in the development of innovative technologies. Within this framework, a myriad of genetic tools has flourished, allowing the design and manipulation of complex synthetic circuits and genomes to become the general rule in many laboratories rather than the exception. More recently, with the development of novel technologies such as DNA automated synthesis/sequencing and powerful computational tools, molecular biology has entered the synthetic biology era. In the beginning, most of these technologies were established in traditional microbial models (known as chassis in the synthetic biology framework) such as Escherichia coli and Saccharomyces cerevisiae, enabling fast advances in the field and the validation of fundamental proofs of concept. However, it soon became clear that these organisms, although extremely useful for prototyping many genetic tools, were not ideal for a wide range of biotechnological tasks due to intrinsic limitations in their molecular/physiological properties. Over the last decade, researchers have been facing the great challenge of shifting from these model systems to non-conventional chassis with endogenous capacities for dealing with specific tasks. The key to address these issues includes the generation of narrow and broad host plasmid-based molecular tools and the development of novel methods for engineering genomes through homologous recombination systems, CRISPR/Cas9 and other alternative methods. Here, we address the most recent advances in plasmid-based tools for the construction of novel cell factories, including a guide for helping with “build-your-own” microbial host.

Potential of a new biotreatment:<Emphasis Type="Italic"> Sphingomonas cloacae</Emphasis> S-3<Superscript>T</Superscript> degrades nonylphenol in industrial wastewater

Sphingomonas cloacae S-3^T, a nonylphenol (NP)-degrading bacterium, was evaluated for its utility in the remediation of NP-contaminated wastewater. In flask-scale experiments, S-3^T cells immobilized on porous polypropylene carriers (beads) efficiently degraded NP to concentrations routinely measured in aquatic environments [a few parts per billion (ppb), or micrograms per liter). Therefore, we constructed and evaluated a laboratory-scale wastewater treatment system with a 3-l carrier-filled column. The system worked properly and consistently removed several hundred ppb of NP to ecologically safe concentrations of less than 10 ppb in industrial wastewater without the addition of nutrients. The effect of wastewater pH on the system performance was also evaluated; and wastewater samples with pH values of 6 or 8 were treated efficiently without pH adjustment. These results suggest that a biotreatment system using NP-degrading bacteria can efficiently remediate industrial wastewater and contribute to the preservation of aquatic environments.     

Analysis of the genome of an alkaliphilic Bacillus strain from an industrial point of view

Bacillus species and other microbes with pH optima for growth higher than pH 9 are defined as alkaliphiles. A large number of alkaliphilic Bacillus strains producing useful enzymes, have been isolated from various environments. Some of these enzymes, such as proteases and cellulases from alkaliphilic Bacillus strains, have been commercialized and have brought great advantages to industry and domestic life. To support further development of the enzyme industry, we initiated analysis of the genome of Bacillus halodurans C-125, which is 4.25 Mb in size, and constructed a physical and genetic map for comparison with the Bacillus subtilis chromosome. Systematic sequencing of the whole genome of Bacillus halodurans C-125 has been automated since the beginning of May 1998, and sequencing of 98% of the whole genome has been done so far. Through genome analysis, it became apparent that the genome organization of alkaliphilic Bacillus halodurans C-125 is totally different from that of B. subtilis orthologues.

Investigation of soluble microbial products in a full-scale UASB reactor running at low organic loading rate

Investigation on a full-scale UASB treating industrial wastewater at a low organic loading rate (OLR) was conducted. Excellent treatment performance was achieved when treating the evaporator condensate of distillery wastewater at the OLR of less than 1 kg COD/m³ d. Anaerobic effluent could be discharged without further treatment, which saved energy and running cost considerably. GC–MS analysis showed that the soluble microbial products (SMPs) were decreased to a low level at the low OLR. The main SMP in the anaerobic effluent were long chain carbohydrates and esters, accounting for 55–65% of the total organic matters. Anaerobic SMP was more complex than the aerobic ones.
