Özet

Hücre dışı
polimerik maddeler (HPM), mikroorganizmalar tarafından salgılanan, hücre
parçalanmasından üretilen yüksek moleküler ağırlıklı kompleks bir polimer
karışımından ve atıksudan adsorbe edilen organik maddelerden oluşmaktadır.
HPM’nin başlıca bileşenleri (karbonhidratlar, proteinler, hümik maddeler ve
nükleik asitler) ve karakteristikleri (adsorpsiyon, biyolojik parçalanabilirlik
ve hidrofiliklik/hidrofobiklik) mikrobiyal agregaların özelliklerini önemli
ölçüde etkilemektedir. HPM, çok kompleks özelliklere sahip olduğundan biyolojik
atıksu arıtma tesislerindeki rollerini tam olarak anlamak için çok çalışma
yapılması gerekmektedir. Bu çalışmada; HPM’nin bileşenleri ve dağılımı, HPM’nin
karakteristikleri, HPM üretimine etki eden faktörler, HPM ekstraksiyonu, HPM
analiz yöntemleri, mikrobiyal agregalarda HPM’nin rolü başlıkları altında HPM
ayrıntılı olarak verilmiştir.
