Isolation and identification of some fungal species contaminating dried dates and the impact of some plant extracts on fungal species contaminating dried dates them

Abstract

The study included the preparation of aqueous extracts (using distilled water) of a group of local plants that included verum (Inamum), mint mint, Anisum pimpinella, Salvia officinalis, for the purpose of studying their effect on a group of pathogenic fungi, using the method of mixing the extracted plant with the nutrient medium at a concentration (5,10,15,20,25) mg/ml. For the effective evaluation of the plant extracts compared to the fungal isolates included in the study and the calculation of the activation ratio and the concentration value.

 Thirty (30) samples of dried palm fruits (Phoenix dactylifera) were collected from street vendors, shops and markets from different regions of Diyala governorate. Detection of fungal species. The investigation was based on cultural, microscopic and biochemical tests. C.guillermondii and C.albicans (7) isolates (23.33%) were diagnosed followed by C.krasei and C.stellatoiclea (5) isolates (16.66%), and C. (3) isolates (10%). So there is a need to treat these fruits appropriately before consumption to reduce the possibility of fungal infection.

Anisum-pimpinella extract concentration (5 mg/ml) is the highest, while (15 mg/ml) is the lowest, Salvia officinalis extract (5 mg/ml) is the highest and (25 mg/ml) is the lowest. The substance with the greatest concentration is inamomum ferrum (25 mg/ml). While the learner with a concentrate on (20 mg / ml) is the lowest, while mint with a concentration of (15) is the highest, while the learner with an emphasis on (25 mg / ml) is the lowest.
