Phage lytic proteins: a natural approach to agro-food safety

引用

Food Science and Human Wellness 2024年

作者： Seila Agún Lucía Fernández Ana Rodríguez pilar García Instituto de Productos Lácteos de Asturias (IPLA-CSIC). DairySafe Group.Instituto de Investigación Sanitaria del Principado de Asturias (ISPA)

Sustainability is a leading trend in the context of food production. Additionally， consumers increasingly demand safer and less-processed products. Among the different technologies used to maintain the quality and extend the shelf-life of fresh and minimally-processed food， natural antimicrobial agents offer a promising strategy to replace conventional compounds. In this regard， phage lytic proteins or lysins， such as endolysins and virion-associated peptidoglycan hydrolases (VAPGHs)， have been proposed as a viable option for the avoidance and elimination of undesirable bacteria within the food production chain. Even when applied exogenously， these proteins can degrade the bacterial cell wall maintaining their lytic activity. This feature， alongside their modular structure， which can be exploited for bioengineering， provides significant biotechnological potential. However， despite the promising properties of lysins， the main obstacle for their commercialization is the limited legal information regulating their use. This challenge underscores the need to navigate complex regulatory pathways. The primary objective of this review is to address this crucial gap and summarize the many prospective applications of endolysins during the different stages of food production. By doing so， we aim to provide clarity and insight into the regulatory challenges that must be overcome for the successful utilization of lysins.

Fungi Associated with Sand and Plants from Marine Coastlines: Potential Relevance for Human Health

引用

Advances in Microbiology 2024年第6期14卷 303-316页

作者： Marina Carrasco-Acosta pilar Garcia-Jimenez Department of Biology Universidad de Las Palmas de Gran Canaria Campus de Tafira Las Palmas Spain

The fungal community associated with beach sand and plants located along marine coasts are an under-studied area of research despite its potential relevance to human health. In this study, we isolated and identified the cultivable mycobiota associated with sand and plants collected along the coast of Gran Canaria (Spain) using culture-dependent and -independent methods. Clinically relevant species belonging to Cryptococcus spp. and related genera such as Naganishia and Papilotrema were isolated and identified from shoreline plants. Moreover, Candida tropicalis was isolated from beach sand, and Aspergillus fumigatus and Aspergillus terreus strains were associated with both types of samples (i.e., plants and beach sand). We conclude that beach sand and shoreline plants are potential reservoirs of fungi of high clinical interest. We recommend including beach sand and plants from the environment when assessing the quality of marine coastal systems. Our results open a framework for studying the natural marine environment and its role in the epidemiology of infectious diseases in order to more accurately manage public health.
