Projects

Research and development of recycling mushroom cultivation waste using insect larvae (2022-2025)
The basic idea behind the project was that during mushroom cultivation, compared to the weight and volume of the mushroom, a multiple amount of harvested compost and other picking "waste" is generated, which due to its large volume can only be economically transported over a limited geographical distance. This nutrient-rich biomass can, however, be suitable for recycling with insect larvae. However, according to the hypothesis of the experts of Bio-Fungi Kft. and MATE, only a very small number of insect larvae can consume the harvested mushroom compost, and within that very few that can effectively utilize the nutrients in the compost. One of the main goals of the project, which is supported by the European Union, is to find the insect species whose larvae can be shown to have a significant positive effect when fed with mushroom compost.

In-depth investigation of the food safety risk of mycotoxins potentially present in the mushroom industry, development of compost production and mushroom cultivation technology using new knowledge (2017-2019)
During the research, we explored the scientific background of the microbiological processes that favorably change the mycotoxin concentration of the mushroom compost and the substrate. We were the first to develop a validated liquid chromatography-mass spectrometry method for the quantitative determination of toxins on mushroom compost matrices. We determined the bacterial species that are suitable for the quantitative breakdown of mycotoxins during mushroom production.
Based on the analytical measurements, we have developed a computerized management method for the mycotoxin monitoring procedure for the mushroom industry. The developed compost registration system, with continuous data registration, is suitable for the production of healthy bio-mushrooms that are safe for the food industry and far below the toxin limit.

Studies aimed at reducing the chemicals used in mushroom cultivation (2013-2015)
As a result of two and a half years of research work, new practical and scientific results that are unique in our country and remarkable at the international level have been produced. Our results regarding organic mushroom cultivation can be summarized below. We have developed a routine procedure that can be used to assess and characterize the hygienic status of conventional and organic mushroom growing plants. We have determined the critical points of mushroom growing plants, which we continuously share with the growers during personal consultations and through trade magazines. As a result of regular plant hygiene surveys, the amount of chemicals used in the cultivation of saffron can be reduced due to the reasonable and targeted use of substances. It has been confirmed that agents with little impact on the environment (e.g. hypo) also have a satisfactory disinfecting effect.
