Abstract:
AbstractA significant number of molecules that are used in contemporary biochemistry on Earth are found in interstellar and circumstellar regions as well as solar system environments. In particular small solar system bodies hold clues to processes that formed our solar system. Comets, asteroids, and meteorite delivered extraterrestrial material during the heavy bombardment phase ~3.9 billion years ago to the young planets, a process that made carbonaceous material available to the early Earth.

Abstract:
The inner Solar System—including the planet Earth—was heavily bombarded by comets, asteroids, and their fragments (i.e., meteorites, micrometeorites, and interplanetary dust particles) from 4.56 to about 3.5 billion years ago. This bombardment resulted in a rich assortment of organics delivered to the Earth, as comets and many asteroids contain carbonaceous material. These organic compounds were likely further processed on the early Earth (e.g., by impact-shock reactions), providing a feedstock of prebiotic molecules to the crust and oceans. In this chapter, we review the mechanisms of organic

Abstract:
Carbon, and molecules made from it, have already been observed in the early Universe. During cosmic time, many galaxies undergo intense periods of star formation, during which heavy elements like carbon, oxygen, nitrogen, silicon and iron are produced. Also, many complex molecules, from carbon monoxide to polycyclic aromatic hydrocarbons, are detected in these systems, like they are for our own Galaxy. Interstellar molecular clouds and circumstellar envelopes are factories of complex molecular synthesis. A surprisingly high number of molecules that are used in contemporary biochemistry on the

Abstract:
The unique rarefied flow and flash heating in meteors creates physical conditions that can change exogenous organic matter into unique prebiotic molecules. with the exception of rare giant comet impacts, most infalling matter at the time of the origin of life was deposited in the atmosphere during the meteor phase. Much new data has been obtained from observations in the Leonid Multi-Instrument Aircraft Campaign; a series of NASA and USAF sponsored Astrobiology missions that explored the 1998–2002 Leonid meteor storms. Here, we provide an overview of some of this recent insight, which provides

Abstract:
Carbonaceous meteorites are fragments of ancient asteroids that have remained relatively unprocessed since the formation of the Solar System. These carbon-rich objects provide a record of prebiotic chemical evolution and a window on the early Solar System. Many compound classes are present reflecting a rich organic chemical environment during the formation of the planets. Recent theories suggest that similar extraterrestrial organic mixtures may have acted as the starting materials for life on Earth.

Abstract:
Public awareness of healthy food is currently getting stronger. Food should be free from antibiotics. As consequence the use of antibiotics as feed additives should be prohibited because it has the potential to produce residues in livestock products and indirectly impact consumers. An alternative substitute for antibiotics that has been widely developed is the administration of synbiotics. Synbiotics are a combination of probiotics and prebiotics. The purpose of this study is to investigate Pediococcus pentosaceus strain N6 isolate as a probiotic and cassava peel as a prebiotic. The research d

The agricultural industry significantly drives global economic growth. However, the undeniable impacts of intensive use of chemical fertilizers, pesticides, and intensified farming practices contribute to soil erosion. Synbiotics, a combination of prebiotic and probiotic offer an alternative approach to preserve and improve the quality of soil. The main objective of this review is to provide comprehensive overview of the application of the synbiotic approach to the productivity of the agriculture.

Abstract:
The advanced version of the author’s inversion concept of the origin of terrestrial life and its application for life in the Universe has been substantiated. A key step in the transition to life consists in the thermodynamic inversion of non-living prebiotic microsystems when the contributions of free energy (F) and information (I) become prevalent over the contribution of entropy (S). It is based the thermodynamic corridor that is mandatory for all chemical scenarios for the origin of life: F + I < S (prebiotic microsystem) → F + I ≈ S (intermediate stage, inversion moment) → F + I > S

Abstract All living beings use the same genetic code; hence they derive from a common ancestor. Carbonaceous meteorites and comets contain organic matter, whose carbon isotopic signature points to an abiotic origin. However, these extraterrestrial precursor molecules of life never reach the complexity of the large molecules of living beings, such as proteins and nucleic acids. Miller’s experiment tried to reproduce the genesis of prebiotic molecules, but it used a reduced atmosphere with methane instead of carbonic dioxide that was unlikely at the time of life’s origin.

Abstract The initial combination of matter was then fixed largely by thermodynamic physicochemical selection (Chapters 2 and 3). However, after rapid cooling and when planets formed, phase separations occurred due to fields of gravity and in these cold bodies some compounds were produced in the presence of others with which they should react but they could not because the temperature was too low. It was then necessary to define many chemicals as components in compartments, not in equilibrated phase systems, in an operational manner.

Abstract We have described the basic principles of chemical binding at equilibrium in Chapters 2-6 after looking at the history of the development of ideas on the constitution of matter and energy in Chapter 1. This allowed us to consider the manner of the eventual appearance of the chemical elements as structured compounds and co-operative, condensed phases on the Earth. Simultaneously, in this process, energy was lost locally from the planet on cooling, but the pathways of energy loss often led also to a variety of chemical systems trapped out of equilibrium (Chapters 7-9).

Given the general trend of energy consumption, which leads to an increase in the amount of energy consumed worldwide, the cost of this energy is constantly increasing and its deficit is growing. Therefore, it is important to solve the problem of creating and large-scale implementation of modern energy-efficient heat technologies that reduce energy. This is especially true for providing the population to food, as an additional complication is that the production and processing of agricultural raw materials occurs in conditions of increased consumption of gas and other energy sources with low co
