Biological Nitrogen Fixation / edited by Frans J. de Bruijn
For agricultural purposes, drought related stresses negatively affect the Rhizobiaceae in at least three ways. Firstly, rhizobial populations are affected by desertification of agricultural soils. Secondly, the quality of dry-base inocula, also called formula, is negatively affected by a drying step, and thirdly, rhizosphere bacteria protect crop-plants against drought. Although survival of cultivatable bacteria has been studied intensively in dry-base seed inocula and in-vitro, thus far research has only marginally addressed the bacterial cell, its cellular structures and physiology. Many questions remain regarding the sensing of and physiological response of rhizobia to desiccation. This review will focus on the three different fractions of cells after desiccation, the membrane compromised cells, the viable but not culturable cells and the culturable cells.
