Anhydrobiosis in tardigrades—The last decade
Journal of Insect Physiology, 2011The current state of knowledge about anhydrobiosis in tardigrades is presented. In response to adverse environmental conditions tardigrades arrest their metabolic activity and after complete dehydration enter the so-called "tun" state. In this ametabolic state they are able to tolerate exposure to various chemical and physical extremes.

Antonie Van Leeuwenhoek, 2014
The yeast Saccharomyces cerevisiae was shown to be extremely sensitive to dehydration-rehydration treatments when stationary phase cells were subjected to conditions of severe oxygen limitation, unlike the same cells grown in aerobic conditions. The viability of dehydrated anaerobically grown yeast cells never exceeded 2 %.

Anhydrobiosis of Adineta ricciae: Costs and Benefits
Hydrobiologia, 2005To study the effect of anhydrobiosis on the rotifer life cycle, we dried a bdelloid species, Adineta ricciae, and determined the life-history traits of 1) the rehydrated animals and 2) the offspring produced after a period of dormancy. In the first experiment, a cohort was dried when 8-days-old, kept dry for 7 days and then rehydrated.

THE ROLE OF VITRIFICATION IN ANHYDROBIOSIS
Annual Review of Physiology, 1998▪ Abstract Numerous organisms are capable of surviving more or less complete dehydration. A common feature in their biochemistry is that they accumulate large amounts of disaccharides, the most common of which are sucrose and trehalose. Over the past 20 years, we have provided evidence that these sugars stabilize membranes and proteins in the dry ...

Anhydrobiosis: A strategy for survival
Advances in Space Research, 1992Many organisms from a wide variety of taxa have the ability to survive extreme dehydration, a phenomenon called "anhydrobiosis." Concomitantly with resistance to the adverse effects of drying, these organisms are also resistant to the effects of freezing to very low temperatures, elevated temperature for brief periods, and the effects of ionizing ...

Trehalose, anhydrobiosis for the eye
Acta Ophthalmologica, 2010Abstract Purpose To determine whether topically applied trehalose could heal ocular surface epithelial disorders caused by ocular surface desiccation. Methods This study used a novel murine model of dry eye induced by continuous controlled low‐humidity air velocity in an intelligently controlled environmental system.

Anhydrobiosis in yeast: Stabilization by exogenous lactose
Microbiology, 2009We have found that incubation in lactose solutions (0.75 M) of yeast culture Saccharomyces cerevisiae sensitive to dehydration damage increased the stability of the cells during dehydration. Simultaneously with this increase in viability, a decrease in plasma membrane permeability during rehydration was seen.

Anhydrobiosis, the exceptional adaptation of some organisms to enter a state approaching suspended animation after losing most cellular water, has fascinated scientists and non-scientists since Anthony van Leeuwenhoek described the phenomenon over 300 years ago.

ANHYDROBIOSIS INCREASES SURVIVAL OF TRICHOSTRONGYLE NEMATODES
Journal of Parasitology, 2006This study demonstrates that infective-stage larvae of 2 trichostrongyle ruminant gastrointestinal nematodes, Haemonchus contortus and Trichostrongylus colubriformis, can enter into anhydrobiotic states when completely desiccated. Larvae of control trichostrongyle species, Heligmosomoides polygyrus and Nippostrongylus brasiliensis, that infect mice ...

Survival kit of Saccharomyces cerevisiae for anhydrobiosis
Applied Microbiology and Biotechnology, 2014Yeast cells are well adapted to interfacial habitats, such as the surfaces of soil or plants, where they can resist frequent fluctuations between wet and dry conditions. Saccharomyces cerevisiae is recognized as an anhydrobiotic organism, and it has been the subject of numerous studies that aimed to elucidate this ability.
