One of the main problems in the poultry industry is the search for a viable replacement for antibiotic growth promoters. This issue requires a “one health” approach because the uncontrolled use of antibiotics in poultry can lead to the development of antimicrobial resistance, which is a concern not only in animals, but for humans as well. One of the promising ways to overcome this challenge is found in probiotics due to their wide range of features and mechanisms of action for health promotion. Moreover, spore-forming probiotics are suitable for use in the poultry industry because of their unique ability, encapsulation, granting them protection from the harshest conditions and resulting in improved availability for hosts’ organisms. This review summarizes the information on gastrointestinal tract microbiota of poultry and their interaction with commensal and probiotic spore-forming bacteria. One of the most important topics of this review is the absence of uniformity in spore-forming probiotic trials in poultry. In our opinion, this problem can be solved by the creation of standards and checklists for these kinds of trials such as those used for pre-clinical and clinical trials in human medicine. Last but not least, this review covers problems and challenges related to spore-forming probiotic manufacturing.
The methodology for assessing the energy efficiency of operating actions during the separation of organic contaminants of wax has been developed. Promising methods of separation of media with complex types of bonds are proposed. The dependences characterizing the energy efficiency of separating methods for the wax raw materials have been determined. Mathematical models are obtained in the form of quadratic polynomials characterizing the influence of design parameters on energy characteristics. The influence of the design parameters of the device and the technological properties of the exposed materials in the form of wax raw materials on the values of active and reactive power has been proved. It has been established that the most rational measure for increasing the energy characteristics of devices for separating wax raw materials is to optimize their design and technological parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
