Characteristics of rice straw and sewage sludge as composting materials in Valencia (Spain).

This work supports the idea that composting can be useful for minimizing the rice straw and sewage sludge environmental impact. Several physical, chemical and microbiological properties of these raw materials were analyzed. The characteristics of the rice straw were complementary to those of the sewage sludge for the application of composting.

The SRD2 gene is involved in Saccharomyces cerevisiae morphogenesis.

Saccharomyces cerevisiaepresents two alternative vegetative forms of growth, switching between yeast forms to pseudohyphal forms depending on the specific environmental conditions. To identify genes involved in cell wall morphogenesis, a haploid S. cerevisiae monomorphic mutant, W27, which exhibits pseudohyphal growth in the absence of the normal external signals that induce the formation of filamentous forms, was characterized.
