Heterotrophic nitrification in an Acid forest soil and by an Acid-tolerant fungus.
Nitrate was formed from ammonium at pH 3.2 to 6.1 in suspensions of a naturally acid forest soil; the maximum rates of formation occurred at ca. pH 4 to 5. Nitrate was also formed from soil nitrogen in suspensions incubated at 50 degrees C. Autotrophic nitrifying bacteria could not be isolated from this soil. Enrichment cultures produced nitrate in a medium with beta-alanine if much soil was ad...
متن کاملDiversity and functional properties of acid-tolerant bacteria isolated from tea plantation soil of Assam
In this study, we report on the bacterial diversity and their functional properties prevalent in tea garden soils of Assam that have low pH (3.8-5.5). Culture-dependent studies and phospholipid fatty acid analysis revealed a high abundance of Gram-positive bacteria. Further, 70 acid-tolerant bacterial isolates characterized using a polyphasic taxonomy approach could be grouped to the genus Baci...
متن کاملCultivation of an obligate acidophilic ammonia oxidizer from a nitrifying acid soil.
Nitrification is a fundamental component of the global nitrogen cycle and leads to significant fertilizer loss and atmospheric and groundwater pollution. Nitrification rates in acidic soils (pH < 5.5), which comprise 30% of the world's soils, equal or exceed those of neutral soils. Paradoxically, autotrophic ammonia oxidizing bacteria and archaea, which perform the first stage in nitrification,...
متن کاملInvestigation of Acid-Neutralizing Property of Bacillus cereus GUF8
Extreme pHs, especially acidic pHs, are among the environmental stresses that some bacteria face. The most important strategies that bacteria employ for acid adaptation include either production of acidophilic proteins, or raising the pH of the microenvironment by secretion of basic compounds including ammonia produced by the action of urease. Considering the importance of acid-neutralizing bac...
متن کاملEffect of Soil Application of Humic Acid and Fluvic Acid on Agronomic traits of Barley
One of the most important issues affecting environmental health and sustainable food production is application of organic fertilizers instead of chemical fertilizers. This study set out to investigate the effect of application of soil humic acid and fulvic acid on barley plant. To this end a factorial experiment was carried out on the basis of randomized complete block design with four replicat...
