The micro- and mycobiota of the fresh eggplant fruits phyllosphere of different botanical varieties Valentyna and Samurai (Japanese agriculture), Clorinda (Egg agriculture), Solaris (American agriculture) was studied. The possibility of oak bark and leaves, juniper berries, St. John’s wort, costmary, common plantain, wormwood and motherwort extracts use is considered. It is recommended to use extracts of oak bark and leaves, juniper berries and St. John’s wort on the base of studies of medicinal and vegetable raw material extracts potential toxicity. The studied extracts have antimicrobial activity against 4 reference strains: E. coli АТСС 25922, S. aureus АТСС 25923, P. aeruginosa АТСС 27853, C. albicans АТСС 885-653. Fungal growth inhibition zones are identified in the studied samples compositions: Cladosporium from 15 mm to 28 mm, Fusarium from 18 mm to 30 mm, Rhizopus from 16 mm to 30 mm. The effect of the film-forming agent type on the fungal culture growth inhibition is studied. It is determined that the medicinal and vegetable raw material extracts composition with chitosan use as film-forming agent has the greatest fungistatic properties. The studies results show the dependence of respiratory intensity on the eggplant fruits variety. The use of film-forming composition of medicinal and vegetable extracts on the base of low molecular weight chitosan reduces the amplitude of eggplant fruits respiration and allows storage prolonging by 2 – 2,3 times. |
