Q

What the defition of obligate aerobes 🖤

A

البكتريا الهوائية اجباريأ :. بكتريا تحتاج الاكسجين للنمو كما تسخدمه ك متقبل الكتىوني نهائي خلال عملية التنفس الهوائي

Q

What the defition of obligate anaerobes ?

A

بكتيريا لاهوائية اجباريا : هي بكتريا لا تحتاج ولا تسخدم الاكسجين بل وتعتبر مادة سامة لها خيث بامكانها ان تقتلها او تمنع نموها💛
They do not need or use o2 but in fact the O2 is toxic substance for them , which etheir kill or inhibits thier growth,💜

Q

What the deifition of facultative anaerobies

A

بكتيريا لاهوائية اختيارية :وهي البكتريا التي بامكانها ان تحول عمليات الايضية هوائية او لا هواىبة
١_تحت ظروف الاهوائية فانها ستنتج طاقة بشكل رئيسي من التخمر
٢_في حالة وجود الاكسجين فانها تحول الى التنفس الهوائي

Q

What the defiftion of aerotolerant anaerobes♥️♥️♥️

A

بكتيريا لاهوائية محتملة الاكسجين : نوع من انواع البكتيريا ع وجه الحصر لاهوائي اي يحتاج الى تخمر ولكن نها غير حساسة او لاتموت بوجود الاكسجين اي انها تعيش بعملية التخمر لوحدها سواء بوجود الاكسجين او عدم وجوده
These are bacteria that are exclusively anaerobic they are insensitive (not killed) to the presence of O2 they live by fermation alone whether or not o2 is present in thier envermrnt
