Abstract This contribution is a scientific journey divided into three parts. In the first part, we review the role that silica biomorphs of alkaline earth metals have played in the formation of complex structures as a reminiscence of the chemistry of the primitive life on Earth. These biomorphs, and their variety of forms synthesized by simple chemical reactions, can nowadays be experimentally used to explain some mechanisms of biomineralization in living organisms. In the second part, we review...

The Earth has undergone at least four great glaciations, during which the ice layers and the glaciers have expanded all over the planet, corresponding to significant drops in global temperatures that lasted millions of years. Since the Precambrian era, ice ages have occurred at intervals of several millions of years. It is considered that the impact on the biosphere was large, because life was on the brink of disappearing completely from the planet. During these glaciation periods, carbon was re...

: The aim of the present work was to evaluate whether Candida species can reduce both precious and toxic pure metals from the respective molecular ions. From these results, the nanoparticles formed were studied using scanning electron microscopy with energy-dispersive spectroscopy, Raman spectroscopy, X-ray fluorescence spectroscopy and synchrotron radiation. Our results showed that the metal ions were reduced to their corresponding metallic nanoconglomerate or nanoparticles by Candida species. ...

A gel can be considered to be a two-phase (liquid and solid) system, which lacks flow once it reaches a stationary state. The solid phase is usually a tridimensional polymeric mesh, while the liquid phase is usually found in three forms: contained in great cavities, retained in the capillary pores between micelles, or adsorbed on the surface of a micelle. The influence of the use of gels in crystal growth is diverse and depends on the type of gel being used. A decrease in solubility of any solut...

The Precambrian era is associated with the origin of life on primitive Earth. It was, in fact, in that era that ribonucleic acid (RNA) was first acquired. From this evolved the genomic deoxyribonucleic acid (DNA) that later generated the biomolecules that formed the first cell. In this way, with the ongoing changes in environmental factors, the first cells evolved to give rise to higher multicellular organisms, i.e., plants and animals. Radiolarians and diatoms are organisms that have been conse...

The origin of life from the chemical point of view is an intriguing and fascinating topic, and is of continuous interest. Currently, the chemical elements that are part of the different cellular types from microorganisms to higher organisms have been described. However, although science has advanced in this context, it has not been elucidated yet which were the first chemical elements that gave origin to the first primitive cells, nor how evolution eliminated or incorporated other chemical eleme...

Abstract Background In the last three decades the species of Candida have been of great interest due to the high mortality rates that they cause in immunocompromised and hospitalized patients. These species are opportunistic pathogens and they have inhabited other environments long before colonizing human cells. Among these environments we find wastewater from mines, and water from aquifers and soils that contain high concentrations of precious metals as well as toxic and base metals. Aims The a...

The use of microorganisms for in vivo synthesis of quantum dots (QDs) not only makes it possible to obtain useful materials with tunable characteristics under mild conditions, but can also ensure the removal of toxic heavy metals from polluted water systems. Because real water treatment schemes contain more than one pollutant, this work attempted to determine the responses of Candida to exposure to two cations with known different survival pathways: Pb(II) and Cd(II). Five Candida species, C. al...
