Burkholderia cepacia complex (Bcc) was originally recognized as a pathogen of onions. It causes sour skin of onions, what is associated with the yellow/brown coloured soft rot of onion tissue. It is a disease very important economically. Additionally, Burkholderia cepacia has positive environmental effects. The bacteria is able to produce antimicrobial compounds that protect plants, as well as some factors that promote plant growth. B. cepacia also can degrade a wide variety of compounds including pollutants, and therefore it might be used as a bioremediation agent.
The problem of waste which amounl is still growing is more and more important. New technologies of its reducing are being searched, especially reducing of organic waste. In this paper many recycling methods of processing vegetable-fruit waste were presented. A lot of valuable substances can be achieved from processing waste. They can be used in food, chemistry, cosmetic and pharmaceutical industry. Some of the waste are used in the production of biogas. From the other valuable manure - compost is produced. The selected strains of Trichoderma fungi are used in decomposition of organic matter. The mass of waste produced from raw materials in vegetable and fruit industry is also carrier for Trichoderma fungi in biopesticides production which are used in crop protection and also as organic fertilizers.
