Abstract

Biofilms are multicellular sessile microbial communities embedded in hydrated extracellular polymeric matrices. Their formation is common in microbial life in most environments, whereas those formed on food-processing surfaces are of considerable interest in the context of food hygiene. Biofilm cells express properties that are distinct from planktonic ones, in particular, due to their notorious resistance to antimicrobial agents. Thus, a special feature of biofilms is that once they have developed, they are hard to eradicate, even when careful sanitization procedures are regularly applied. A large amount of ongoing research has investigated how and why surface-attached microbial communities develop such resistance, and several mechanisms can be acknowledged, such as heterogeneous metabolic activity, cell adaptive responses, diffusion limitations, genetic and functional diversification, and microbial interactions. The articles contained in this Special Issue deal with biofilms of some important food-related bacteria (including common pathogens such as Salmonella enterica, Listeria monocytogenes, and Staphylococcus aureus, as well as spoilage-causing spore-forming bacilli), providing novel insights into their resistance mechanisms and implications, together with novel methods (e.g., use of protective biofilms formed by beneficial bacteria, enzymes) that could be used to overcome resistance and thus improve the safety of our food supply and protect public health.

Abstract

For some legal philosophers, if a law is procedurally correct, enacted in ways constitutionally recognised and agreed upon, then the content is of no significance. It is a "good" law, no matter what it does or justifies. The question of one's consent or opposition to any particular law is extraneous to the legality and is regarded merely as a political matter. The assumption is that a certain procedure and logic in law creation has taken place, and the law can be altered by a change in political leaders in a subsequent political election. However, this view and assumption obscure an uncomfortable fact. Some laws can be "bad" or "immoral." Critical legal theory suggests that there are often two (or more) sets of laws, and it makes no difference if Lady Justice is blindfolded or not. Laws change in the process of history, in part, because societal norms change. As common understandings of morality evolve, law adapts itself to the new moral environment. Norms can change slowly or rapidly, even within a lifetime. This book examines both social and legal norms and theories of how they are both created. Christine M. Hassenstab investigates how laws on sterilization, birth control and abortion were created, by focusing on the act of legislation; how the law was driven by scientific and social norms during the first and closing decades of the 20th century in the USA (especially in the state of Indiana) and Norway. The primary focus of Body Law and the Body of Law is the sociology of law and how and why the law changes. The author develops the notion "body law" for reproductive policies and uses sociological theories to untie the various strands of social history and legal history and looks at two cases of legislation. The book is divided in to two main sections. The first examines eugenic laws in the USA state of Indiana and Norway during the first decades of 20th century. The second part is about the birth control and abortion debate in both countries throughout the late 1960's and 1970's.Christine M. Hassenstab is a lawyer and sociologist. She served as a criminal defense attorney for 15 years (1987-2001) in Seattle, Washington. Currently, she is an adviser in the EU Grants Office at the Norwegian University of Science and Technology in Trondheim, Norway.

Abstract

According to a report from the U.S. Centers for Disease Control and Prevention (CDC), achieving safe and healthier foods was one of the top ten achievements of public health in the 20th century. However, considerable persisting challenges currently exist in developed nations and developing economies for further assuring the safety and security of the food supplies. According to CDC estimates, as many as 3000 American adults, as an example, and based on a recent epidemiological estimate of the World Health Organization, around 420,000 individuals around the globe, lose their lives annually due to foodborne diseases. This emphasizes the need for innovative and emerging interventions, for further prevention or mitigation of the risk of foodborne microbial pathogens during food processing and manufacturing. The current publication discusses recent advancements and progress in the elimination and decontamination of microbial pathogens during various stages of manufacturing and production. Special emphasis is placed on hurdle validation studies, investigating decontamination of non-typhoidal Salmonella enterica serovars, various serogroups of Shiga toxin-producing Escherichia coli, public health-significant serotypes of Listeria monocytogenes, and pathogenic species of Cronobacter.

Abstract

This Special Issue of the International Journal of Molecular Science comprises a comprehensive study on “Antimicrobial Materials with Medical Applications”. The Special Issue has been inspired by the great progress made in the development of new antimicrobial materials that go beyond the resistance of microbes to modern antibiotics. It covers a selection of recent research and review articles in the field of antimicrobial materials and their medical applications. Moreover, it also provides an overview of this increasingly diverse field, presenting recent developments and the latest research, with particular emphasis on new antimicrobial surfaces, medical devices, contact lens, package materials, etc.

Abstract

Biomass can be used as feedstock for the production of biomaterials, chemicals, platform molecules and biofuels. It is the most reliable alternative to reduce fossil fuel consumption and greenhouse gas emissions. Within the framework of the circular economy, resource recovery from organic waste, including sewage sludge, biowaste, manure and slaughterhouse waste, is particularly useful, as it helps saving resources while reducing environmental pollution. In contrast to energy crops, lignocellulosic biomass and algae do not compete for food production; therefore, they represent an important source of biomass for bioenergy and bioproducts. However, biomass may require a pretreatment step in order to enhance its conversion into valuable products in terms of process yield and/or productivity. Furthermore, a pretreatment step may be mandatory for waste management (i.e., animal by-products).Pretreatment technologies are applied upstream of various conversion processes of biomass into biofuels or biomaterials, including bioethanol, biohydrogen, biomethane, biomolecules or bioproducts. Pretreatments may include mechanical, thermal, chemical and biological techniques, which represent a crucial, cost-intensive step for the development of biorefineries. Thus, research is needed to help identify the most effective, economic, and environmentally friendly pretreatment options for each feedstock. This Special Issue aims to gather recent developments of biomass pretreatments for bioproduct and biofuel production.
