Effect of baker's yeast separation effluent on barley (Hordeum vulgare) germination and growth.

Industrial waste; whatever the form in which it is released, still present as environmental dangers for the nature and survival of all living beings. Among these toxic products, the focus has been on liquid effluents from the baker's levy industry that cause real environmental problems throughout the Mediterranean region and precisely in Tunisia. In order to minimize these hazards and to take advantage of these wastes for the sake of our environment, the present work consists of valuing the effects of these effluents on the germination and growth of one of the main cereals our country which is barley. This has been put into play, using different doses of effluent solutions with or without dilution. The results showed that this waste is characterized by its richness in organic matter, and the presence of proteins traces. On the other hand, the microbiological analysis shows high rates of microbial load of coliforms and total germs. Furthermore, no phytotoxic effect of this effluent has been demonstrated, especially at a volume of 5 ml of diluted and filtered solution, the latter has triggered better germination and growth of the plant almost similar to that of the control.
