Özet
Biyoteknolojide son gelişmelerden biri de organik ve inorganik kirleticileri yüksek oranda tutma kapasitesi olan biyolojik kökenli yeni adsorbentlerin belirlenmesi yönündedir. Yeni bir biyosorbent olarak Penicillium lanosa-coeruleunı biyokütlesinin ağır metal biyosorpsiyon kapasitesi üzerine ön işlemlerin etkisi incelenmiştir. Bakır, kurşun ve nikel iyonlarının biyosorpsiyonu üzerine etkisini incelemek üzere, biyokütle ısı ve kimyasal işlemlere (sodium hidroksit, hidrojen peroksit, ticari çamaşır deterjanı ve dimetil sulfoksit) maruz bırakılmıştır. Canlı biyokütle ile kıyaslandığında, biyokütlenin ısı, sodyum hidroksit ve deterjanla ön işlemi kurşun (%27) ve bakır (% 106, %95, %162) biyosorpsiyonunu önemli oranda artırırken, glutaraldehitle ön işlemi nikel (% 72) biyosorpsiyonunu artırmıştır. P. lanosa-coeruleum biyokütlesi, atık sulardan kurşun, bakır ve nikel giderimi için düşük maliyetli, etkili bir biyosorbent geliştirilmesinde kullanılabilir
One of the recent developments in biotechnology is the identifıcation of a new type of adsorbents of biological origin which have high sequestering capacity for organic or inorganic pollutants. The effect of pretreatment on the heavy metal biosorption capacity of Penicillium lanosa-coeruleum biomass was investigated as a new biosorbent. The biomass was subjected to heat and chemical treatmenis including sodium hydroxide, formaldehyde, glutera ldehyde, acetic acid, hydrogen peroxide, detergent and dimethyl sulfaxide to study their effects on biosorption of copper, lead and nickel. It was found that heat, sodium hydroxide and detergent pretreatments signifıcantly improved biosorption of lead (27%) and copper (106%, 95%, 162%) whereas gluteraldehyde increased nickel biosorption (72%) in comparison with the living biomass. The fungal biomass of P. lanosa-coeruleum may be applied to develop an inexpensive, effective biosorbent for removing lead, copper and nickel from waste waters.
