Comprehensive studies of the biodiversity of the microbial epilithic community on monuments may provide critical insights for clarifying factors involved in the colonization processes. We carried out a high-throughput investigation of the communities colonizing the medieval church of San Leonardo di Siponto (Italy) by Illumina-based deep sequencing. The metagenomic analysis of sequences revealed the presence of Archaea, Bacteria, and Eukarya. Bacteria were Actinobacteria, Proteobacteria, Bacteroidetes, Cyanobacteria, Chloroflexi, Firmicutes and Candidatus Saccharibacteria...

Liberal proponents of genetic engineering maintain that developing human germline modification technologies is morally desirable because it will result in a net improvement in human health and well-being. Skeptics of germline modification, in contrast, fear evolutionary harms that could flow from intervening in the human germline, and worry that such programs, even if well intentioned, could lead to a recapitulation of the scientifically and morally discredited projects of the old eugenics. Some bioconservatives have appealed as well to the value of retaining our "given" human biological nature as a reason for restraining the development and use of human genetic modification technologies even where they would tend to increase well-being...

According to human enhancement advocates, it is morally permissible (and sometimes obligatory) to use biomedical means to modulate or select certain biological traits in order to increase people's welfare, even when there is no pathology to be treated or prevented. Some authors have recently proposed to extend the use of biomedical means to modulate lust, attraction, and attachment. I focus on some conceptual implications of this proposal, particularly with regard to bioconservatives' understanding of the notions of therapy and enhancement I first explain what makes the proposal of medicalizing love interesting and unique, compared to the other forms of bioenhancement usually advocated...

Antimicrobial resistant zoonotic pathogens present on food constitute a direct risk to public health. Antimicrobial resistance genes in commensal or pathogenic strains form an indirect risk to public health, as they increase the gene pool from which pathogenic bacteria can pick up resistance traits. Food can be contaminated with antimicrobial resistant bacteria and/or antimicrobial resistance genes in several ways. A first way is the presence of antibiotic resistant bacteria on food selected by the use of antibiotics during agricultural production...

Bioconservative commentators argue that parents should not take steps to modify the genetics of their children even in the name of enhancement because of the damage they predict for values, identities and relationships. Some commentators have even said that adults should not modify themselves through genetic interventions. One commentator worries that genetic modifications chosen by adults for themselves will undermine moral agency, lead to less valuable experiences and fracture people's sense of self. These worries are not justified, however, since the effects of modification will not undo moral agency as such...

Both, bioconservatives and bioliberals, should seek a discussion about ideas of human perfection, making explicit their underlying assumptions about what makes for a good human life. This is relevant, because these basic, and often implicit ideas, inform and influence judgements and choices about human enhancement interventions. Both neglect, and polemical but inconsistent use of the complex ideas of perfection are leading to confusion within the ethical debate about human enhancement interventions, that can be avoided by tackling the notion of perfection directly...

The main objective of this article is to suggest a panel of the different positions active in the human enhancement's debate, to analyze their arguments and to point out the dividing zones. The transhumanist movement is therefore presented in order to highlight the principal thematic of its philosophy, its means of action and the plurality of its subgroups. The purpose is to reassess its complexity in an introductory manner far from the usual, excessive simplifications. In a second time, the "bioconservative" movement is also examined in its foundations to emphasize the norms and principles that are undoubtedly shared by the opponents to the human being's modification...

The deterioration of the stone built and sculptural heritage has prompted the search and development of novel consolidation/protection treatments that can overcome the limitations of traditional ones. Attention has been drawn to bioconservation, particularly bacterial carbonatogenesis (i.e. bacterially induced calcium carbonate precipitation), as a new environmentally friendly effective conservation strategy, especially suitable for carbonate stones. Here, we study the effects of an in situ bacterial bioconsolidation treatment applied on porous limestone (calcarenite) in the sixteenth century San Jeronimo Monastery in Granada, Spain...

This study aimed to characterize the microbiological quality and safety of raw milk and soft cheese, verifying possible associations between microbial populations, and the detection of lactic acid bacteria (LAB) with antagonistic activity against foodborne pathogens. Raw milk (n = 36) and soft cheese (n = 18) samples were collected and submitted for the analysis of mesophilic aerobes, total coliforms, Escherichia coli, LAB, coagulase-positive Staphylococcus (CPS), Listeria monocytogenes, and Salmonella spp...

We consider the current debate between bioconservatives and their chief opponents--whom we dub bioliberals--about the moral acceptability of human enhancement and the policy implications of moral debates about enhancement. We argue that this debate has reached an impasse, largely because bioconservatives hold that we should honour intuitions about the special value of being human, even if we cannot identify reasons to ground those intuitions. We argue that although intuitions are often a reliable guide to belief and action, there are circumstances in which they are not reliable...

A bacterium capable of producing Coenzyme Q10 (CoQ10, was isolated from soil. Based on analysis of the 16S rDNA sequence, traditional physiological characteristics, and Biolog-GN, the strain was belonging to the genus Sphingomonas and named as Sphingomonas sp. ZUTEO3. The optimum fermentation condition of CoQ10 production was as following: glucose 15 g/L, (NH4)2SO4 10 g/L, original pH 8.0 and at 25 degrees C. The addition of solanesol could improve CoQ10 production. The optimal condition for the bioconservation from solanesol to CoQ10 was as following: adding 0...

Phylogenetic diversity (PD) is a useful metric for selecting taxa in a range of biological applications, for example, bioconservation and genomics, where the selection is usually constrained by the limited availability of resources. We formalize taxon selection as a conceptually simple optimization problem, aiming to maximize PD subject to resource constraints. This allows us to take into account the different amounts of resources required by the different taxa. Although this is a computationally difficult problem, we present a dynamic programming algorithm that solves it in pseudo-polynomial time...

This study characterized autochthonous pig breeds of Vietnam and compared them with breeds from other regions. A total of 343 animals were considered from 5 indigenous pig breeds of Vietnam (Muong Khuong, Co, Meo, Tap Na, and Mong Cai), 2 exotic breeds kept in Vietnam (Landrace and Yorkshire), 3 European commercial breeds (German Land-race, Piétrain, and Large White), the Chinese breed Meishan, and the European Wild Boar. Each individual was genotyped for 20 selected polymorphic microsatellite loci. The Vietnamese autochthonous breeds showed higher degrees of polymorphism, allelic diversity, and heterozygosity than the other pig breeds...

The aim of this study was to elucidate the vasodilating mechanism of sodium nitroprusside (SNP). To do this, SNP was intravenously infused in pigs (1.67 micromol/kg), and the following paramagnetic metabolites were identified by electron spin resonance: 1) nitrosylhemoglobin [HbFe(II)NO] as an index of the bioconservative pathway; 2) transferrin; 3) [Fe((II))(CN)(5) NO](3-) and [Fe((II))(CN)(4) NO](2-), the reduced penta- and tetracoordinated intermediates of SNP, respectively; and 4) methemoglobin (met-Hb)...

Positions on the ethics of human enhancement technologies can be (crudely) characterized as ranging from transhumanism to bioconservatism. Transhumanists believe that human enhancement technologies should be made widely available, that individuals should have broad discretion over which of these technologies to apply to themselves, and that parents should normally have the right to choose enhancements for their children-to-be. Bioconservatives (whose ranks include such diverse writers as Leon Kass, Francis Fukuyama, George Annas, Wesley Smith, Jeremy Rifkin, and Bill McKibben) are generally opposed to the use of technology to modify human nature...

A saturated nitric oxide (NO) solution (1.88 mM) infused i.v. in the anesthetized pig at a dose of 68 nmol/kg/min for 24 min resulted in a time-dependent increase of nitrosylhemoglobin [HbFe(II)NO] as determined by electron spin resonance (ESR), reaching a C(max) of 7.99 +/- 0.42 microM at the end of the infusion, compared to 1.13 +/- 0.42 microM before (p < 0.01). This indicates that NO i.v. is efficiently bioconserved as HbFe(II)NO (approximately 34% of the NO dose) and to a greater extent than by the oxidative pathway (approximately 24% of the NO dose), as determined by measuring plasma nitrites/nitrates (chemiluminescence) and Met-Hb (ESR analysis)...

This work presents results of the observations of cabbage and carrot juice fermentation after inoculation with pure cultures of lactic acid bacteria. From the point of view of nitrates, utilisation, the most suitable microorganisms found from those studied were Lactobacillus plantarum 92H, Lb. plantarum 90H and Lb. delbrueckii 37H. At the same time, other observed parameters were assessed as well for their suitability for vegetable bioconservation.
