الملخص
يعتبر فطر Aspergillus من أكثر أنواع الفطريات التي تلوث الخضروات وله أهمية كبيرة اذ يُستخدم في صناعات الغذاء والصيدلة. ومن ناحية أخرى، بعضها يكون ضارًا لصحة الإنسان. في هذه الدراسة، تم دراسة الخصائص المورفولوجية والفيسيولوجية لبعض أنواع هذا الفطر مثلA. niger ، A. flavus، A. fumigatus، A. tubingensis، وأنواع Aspergillus أخرى تم عزلها من ثمار الخضراوات (البصل، الجزر، الفلفل، الخيار، والطماطم) وزُرعت في وسط بطاطس الديكستروز لمدة أسبوع. بعد ذلك، تم دراسة الخصائص الماكروسكوبية للمستعمرة بالعين المجردة والفحص المجهري. وقد تم التوصل إلى واحدة من أهم النتائج وهي سرعة نمو هذه الأنواع وتكيُّفها مع الظروف المحيطة. والشبه بين أنواع أسبيرجيلوس السوداء والتباين بين الأنواع الأخرى. بالإضافة إلى ذلك، يتمثل العلاقة بين الخصائص المورفولوجية والفسيولوجية لهذه الأنواع في قدرتها على إفراز الإنزيمات، والسموم، والمركبات الحيوية الأساسية، والأيض. نظرًا لأهمية الخصائص المورفولوجية وعلاقتها بالخصائص الفيسيولوجية لأنواع أسبيرجيلوس، نوصي بتوسيع الدراسات لتشمل المزيد من الأنواع في ظروف بيئية مختلفة ومناطق متعددة بناءً على التأثير الذي يمثله ذلك على هذه الخصائص وللحصول على معلومات دقيقة وشاملة أكثر.
