This work deals with the survival analyses of the symbionts isolated from the lichen E. pusillum under desiccation and starvation
stress. The mycobiont of the symbionts was under the desiccation in combination with starvation stress, and under starvation
stress alone as well. The phycobiont of the symbionts was under desiccation stress alone. The experiments were detected
by means of the biomass size, weight and cell density, deformity of the hyphae and cells, and metabolic activity through SEM
(scanning electron microscopy), TEM (transmission electron microscopy), FM (fluorescence microscopy), spectrophotometry,
and FCM (flow cytometry). The results show that the mycobiont can survive for seven months under desiccation stress in combination
with starvation stress, and for eight months under starvation stress alone. The phycobiont can survive for two months
under desiccation stress. It can provide a scientific basis for further research of the reproduction biology of lichens and arid
desert biocarpet engineering to fix sand and carbon.
