Microbial Mats by Joseph Seckbach,Aharon Oren Pdf

This book provides information about microbial mats, from early fossils to modern mats located in marine and terrestrial environments. Microbial mats – layered biofilms containing different types of cells – are most complex systems in which representatives of various groups of organisms are found together. Among them are cyanobacteria and eukaryotic phototrophs, aerobic heterotrophic and chemoautotrophic bacteria, protozoa, anoxygenic photosynthetic bacteria, and other types of microorganisms. These mats are perfect models for biogeochemical processes, such as the cycles of chemical elements, in which a variety of microorganisms cooperate and interact in complex ways. They are often found under extreme conditions and their study contributes to our understanding of extremophilic life. Moreover, microbial mats are models for Precambrian stromatolites; the study of modern microbial mats may provide information on the processes that may have occurred on Earth when prokaryotic life began to spread.

Role of Microbial Communities for Sustainability by Gamini Seneviratne,Junaida Shezmin Zavahir Pdf

This book is about the role played by microbes in their community mode in sustaining ecosystems. The descriptions given in its chapters indicate clearly that microbial communities are more effective in delivering multifaceted benefits to the soil-plant system than those offered by microbial monocultures in planktonic modes. The role these communities play in a multitude of microbe-microbe and plant-microbe interactions have not yet been fully exploited to gain benefits in this field as well as to achieve sustainability in agriculture practices. Amply discussed are the beneficial characteristics and metabolic capacities of specific microbial groups and the use of microbial traits for the benefit of plant growth. The book suggests the need to develop new microbial technologies to utilize plant-associated microbes for increased crop productivity and agroecosystem balance in order to ensure sustainability. This also provides an effective guidance to scientists, academics, researchers, students and policy makers of the sphere to achieve the above outcomes.

From Assessing to Conserving Biodiversity by Elena Casetta,Jorge Marques da Silva,Davide Vecchi Pdf

This open access book features essays written by philosophers, biologists, ecologists and conservation scientists facing the current biodiversity crisis. Despite increasing communication, accelerating policy and management responses, and notwithstanding improving ecosystem assessment and endangered species knowledge, conserving biodiversity continues to be more a concern than an accomplished task. Why is it so?The overexploitation of natural resources by our species is a frequently recognised factor, while the short-term economic interests of governments and stakeholders typically clash with the burdens that implementing conservation actions imply. But this is not the whole story. This book develops a different perspective on the problem by exploring the conceptual challenges and practical defiance posed by conserving biodiversity, namely: on the one hand, the difficulties in defining what biodiversity is and characterizing that “thing” to which the word ‘biodiversity’ refers to; on the other hand, the reasons why assessing biodiversity and putting in place effective conservation actions is arduous.

Biofilms in Plant and Soil Health by Iqbal Ahmad,Fohad Mabood Husain Pdf

Biofilms are predominant mode of life for microbes under natural conditions. The three-dimensional structure of the biofilm provides enhanced protection from physical, chemical and biological stress conditions to associated microbial communities. These complex and highly structured microbial communities play a vital role in maintaining the health of plants, soils and waters. Biofilm associated with plants may be pathogenic or beneficial based on the nature of their interactions. Pathogenic or undesirable biofilm requires control in many situations, including soil, plants, food and water. Written by leading experts from around the world, Biofilms in Plant and Soil Health provides an up-to-date review on various aspects of microbial biofilms, and suggests future and emerging trends in biofilms in plant and soil health. Issues are addressed in four sub areas: I) The fundamentals and significance of biofilm in plant and soil health, and the concept of mono and mixed biofilms by PGPR and fungal biofilms. II) Biochemical and molecular mechanisms in biofilm studies in plant associated bacteria, and techniques in studying biofilms and their characterization, gene expression and enhanced antimicrobial resistance in biofilms, as well as biotic and biotic factors affecting biofilm in vitro. III) The ecological significance of soil associated biofilms and stress management and bioremediation of contaminated soils and degraded ecosystems. IV) Pathogenic biofilm associated with plant and food and its control measures. This book is recommended for students and researchers working in agricultural and environmental microbiology, biotechnology, soil sciences, soil and plant health and plant protection. Researchers working in the area of quorum sensing, biofilm applications, and understanding microbiome of soil and plants will also find it useful.

Emerging Strategies in Combatting and Managing Bacterial Biofilms by Reham Wasfi,Samira Mohamed Hamed,Ashraf Zarkan Pdf

Biofilm formation is a survival strategy for many microorganisms. Within biofilms, microorganisms live in multicellular communities enclosed in a protective matrix that enables them to survive harsh conditions and resist conventional treatments. The ability of biofilm-forming microorganisms to inhabit different biotic and abiotic surfaces facilitates their widespread existence in different environments including health care facilities, water systems, ships, and even living hosts. Hence, this microbial phenotype became a major concern in various sectors including public health, medicine, and industry. The challenge imparted by the detrimental effects of biofilms has sparked the interest of many researchers in tackling this problem. Biofilms are not simply a collection of microorganisms but can be considered as new materials. Current research efforts have focused on understanding the mechanisms of biofilm formation and factors affecting their structures, as well as innovative approaches for combating biofilms and achieving rapid biofilm detection. Prevention and proper management of biofilms necessitates a deep understanding of the mechanisms of their formation and the factors affecting their development. It is established that biofilm formation undergoes multiple stages from initial surface adhesion to maturation and dispersion. However, how bacteria trigger, regulate and modulate each stage is not yet well understood. Additionally, early detection of biofilms facilitates early intervention and, consequently, reduction in the economic loss and clinical burden. However, detection of cells within biofilms is particularly challenging and innovative sensing, tracking and diagnostic technologies are needed. Clinically, biofilm formation is a key aspect of antibiotic resistance. Biofilms are not merely protective barriers against antibiotics and the host immune system, but also harbour non-growing “persister” bacteria that survive antibiotics by virtue of their dormancy. It is established that both persisters and biofilms are implicated in chronic infections. However, the triggering factors of their formation are not fully understood. Viable but non culturable (VBNC) cells is another group of non-growing bacteria that can inhabit biofilms and remain dormant for extended periods. The trigger for their formation and revival as well as clinical relevance is unclear.

Recent Advancements in the Diagnosis of Human Disease by Irshad M. Sulaiman Pdf

Viruses, bacteria, fungi and parasites are known to cause the most common human disease. It frequently spreads through direct contact (from human to human, animal to human), and through contaminated food or water. With the advancement of diagnostic techniques, it is now possible to rapidly identify microorganisms causing human disease and correlate with the corresponding clinical infection. Therefore, there is a need to develop robust and high-throughput diagnostic methods to prevent and control human disease of public health importance. This book entitled “Recent Advancements in the Diagnosis of Human Disease” will help the scientific community to better understand the transmission dynamics of some human diseases.

Biofilms from a Food Microbiology Perspective: Structures, Functions and Control Strategies by Avelino Alvarez-Ordóñez,Romain Briandet Pdf

Materials and equipment in food processing industries are colonized by surface-associated microbial communities called biofilms. In these biostructures microorganisms are embedded in a complex organic matrix composed essentially of polysaccharides, nucleic acids and proteins. This organic shield contributes to the mechanical biofilm cohesion and triggers tolerance to environmental stresses such as dehydratation or nutrient deprivation. Notably, cells within a biofilm are more tolerant to sanitation processes and the action of antimicrobial agents than their free living (or planktonic) counterparts. Such properties make conventional cleaning and disinfection protocols normally not effective in eradicating these biocontaminants. Biofilms are thus a continuous source of persistent microorganisms, including spoilage and pathogenic microorganisms, leading to repeated contamination of processed food with important economic and safety impact. Alternatively, in some particular settings, biofilm formation by resident or technological microorganisms can be desirable, due to possible enhancement of food fermentations or as a means of bioprotection against the settlement of pathogenic microorganisms. In the last decades substantial research efforts have been devoted to unravelling mechanisms of biofilm formation, deciphering biofilm architecture and understanding microbial interactions within those ecosystems. However, biofilms present a high level of complexity and many aspects remain yet to be fully understood. A lot of attention has been also paid to the development of novel strategies for preventing or controlling biofilm formation in industrial settings. Further research needs to be focused on the identification of new biocides effective against biofilm-associated microorganisms, the development of control strategies based on the inhibition of cell-to-cell communication, and the potential use of bacteriocins, bacteriocin-producing bacteria, phage, and natural antimicrobials as anti-biofilm agents, among others. This Research Topic aims to provide an avenue for dissemination of recent advances within the “biofilms” field, from novel knowledge on mechanisms of biofilm formation and biofilm architecture to novel strategies for biofilm control in food industrial settings.
