Alkaline Environment - an overview | ScienceDirect Topics
An alkaline environment refers to a soil or medium with a high pH level above 7, which can induce nutrient deficiencies in plants by making certain nutrients inaccessible. Some plants have adaptations to cope with alkaline environments by secreting organic acids to solubilize nutrients.
Microbial Life in Alkaline Environments - SERC
2006年9月12日 · Cells face many challenges in an alkaline environment. Of greatest significance is the ability to maintain internal pH. If cells are to survive in an alkaline environment, they must make their cytoplasm more acidic to buffer the alkalinity.
Alkaline Environment - Corrosionpedia
2024年7月19日 · What Does Alkaline Environment Mean? An alkaline environment is a setting that is strongly basic or contains alkali components. This usually refers to an environment with a pH value higher than 7.0, since a pH below 7.0 is considered acidic. Alkaline environments are less prone to cause corrosion than acidic environments, but it is possible for ...
Stable alkaline conditions are caused by an unusual combination of climatic, geological, and topological conditions. Soda lakes represent the most stable high-pH environments on Earth and commonly have pH values above 11.5.
Revealing the role of double-layer microenvironments in pH
2023年10月31日 · In order to obtain the molecular pictures of double-layer microenvironments around metal reactive center at alkaline and acid interfaces under ORR conditions, the FeCo-N 6 -C/electrolyte...
Alkaline Environment - an overview | ScienceDirect Topics
Potential fuels, such as alcohols, borohydrides, ammonia, hydrazine, and other relatively complex molecules, have faster oxidation kinetics in alkaline media, making alkaline fuel cells the technology of choice. An alkaline environment is also considered as less corrosive
Challenges and Adaptations of Life in Alkaline Habitats
2019年7月5日 · Studies on alkaline active enzymes are done to understand the molecular mechanisms behind their structural and functional adaptation to high pH environment. Comparative sequence analysis and mutational studies revealed that alkaline-active enzymes exhibit reduced alkali susceptible residues and tend to increase alkali tolerant residues ...
Due to the recent development of electrochemical oxidation tech-nology, including water, biomass, and alcohols, etc., and the demand of clean energy and green environment, we found the electrochemical urea oxidation reaction is also a promising key to unlock the above issues.
Microbial Diversity and Ecology of Alkaline Environments
Alkaliphiles are usually defined as organisms that grow at alkaline pH, with pH optima for growth around two pH units above neutrality (Kroll, 1990) although growth conditions may influence the pH range for growth (Horikoshi 1998). In this chapter, the term...
Bacterial Diversity in a Nonsaline Alkaline Environment: …
2004年3月23日 · Nonsaline alkaline environments are much more rare; their genesis is dependent on complex geological contexts, but they are probably all related to a single geochemical process known as serpentinization.
