(1) Microbiotic soil crust exists in desertification-prone areas.

(2) Soil hydrological process of microbiotic crusts (MC) has been a most debated problem with so much academic concerns all along.

(3) Soil microbiotic crusts are widespread in arid and semiarid regions, they are one of the major components of desert ecosystems, and their importance has been demonstrated by numerous researches.

(4) The results showed: the microbiotic soil crust inhibited the growth of the plant after promoting it in Northern semi-arid region.

(5) Intercepted precipitation and enhanced evaporation by microbiotic crusts were the two main factors threatening the water reservoir in sand dunes.

(6) In artificial vegetation-fixed sandy dunes, microbiotic crusts always occur with stabilizing of the environmental conditions in vegetation regions.

(7) Simultaneously, there is increased microbiotic invasion, due to increased nosocomial exposure, intestinal translocation, aspiration, skin lesions, and trauma.

(8) The relationship between microbiotic crust and soil hydrology has been being the most disputed hotspot in the microbiotic soil crust research field.

(9) The role and function of microbiotic crust in ecological restoration of arid and semiarid regions of China were discussed.

(10) Soil microbiotic crust is developed broadly and has an ecological significance in arid and semiarid regions.

(11) In arid and semi-arid zones[http://], appearance of microbiotic crusts will change the surface condition of sand dunes greatly.

(12) Experiments on seed germination and seedling emergence of two annual plants in microbiotic crusts and sand (as for contrast) were conducted in greenhouse.

(13) OBJECTIVE To investigate the incidence, relative factors of antibiotic related diarrhea and the effect of microbiotic therapy in the newborns.

(14) Objective To find the evidence of the effect of microbiotic collagenase in root surface caries by observing the destruction of collagenous matrix on root surface.
