Microbial Analysis, Physicochemical Content and Insect Vectors Associated with Selected Dumpsites in Ijebu-Ode, Nigeria

Öz

This study analyzed the types of insect vectors in dumpsite locations and the microorganisms associated with the insect vectors and dumpsites. The physicochemical and heavy metal content of the soil samples were also determined. Bacteria and fungi were isolated from the soils, housefly and cockroaches collected from the dumpsites. Atomic absorption spectrophotometer was used to determine the mineral content of the soil samples. Bacterial and fungal counts were also determined using the Quebec colony counter. Dehydrogenase, phosphatase, catalase, urease and peroxidase activities were estimated. Of the ten bacterial species identified Pseudomonas aeruginosa was the most prevalent isolate occurring at all the samples collected with a frequency of 20.3% while Streptococcal faecalis had the least percentage frequency of 3.1%. Seven fungal genera were identified. They include; Aspergillus niger, Trichoderma spp, Penicillium spp. The study showed a statistically significant (P<0.05) increase in the enzyme activities of the enzymes in the soil samples from the dumpsites compared to the control. Peroxidase and catalase activities of dumpsite soils were significantly higher (P≤0.05) than their control soil samples. There were significant differences (P≤0.05) in the mineral and heavy metal content of soil samples. The Na, Fe, Zn, Cu, Pd and Cd contents of the dump site soil samples were significantly higher than their control soil samples. However, the Ca, Mg, K contents of the control soil samples were significantly higher than those of the dump site soils. Fe had the highest value of 33.57±10.22 mg/kg compared to the other soil samples.

Nijerya’nın Ijebu-Ode Bölgesinde Seçilmiş Çöp Depolama Alanlarıyla İlişkili Mikrobiyal Analiz, Fizikokimyasal Bileşim ve Böcek Vektörleri

Öz

Bu çalışmada, çöp depolama alanlarında bulunan böcek vektörlerinin türleri ile bu böcek vektörleri ve depolama alanlarıyla ilişkili mikroorganizmalar incelenmiştir. Ayrıca, toprak örneklerinin ağır metal ve fiziko-kimyasal içerikleri de belirlenmiştir. Çöp depolama alanlarından toplanan toprak, ev sineği ve hamamböceği örneklerinden bakteri ve mantarlar izole edilmiştir. Toprak örneklerinin mineral içeriklerinin belirlenmesinde atomik absorpsiyon spektrofotometresi kullanılmıştır. Bakteri ve mantar sayımları ise Quebec koloni sayacı kullanılarak gerçekleştirilmiştir. Dehidrogenaz, fosfataz, katalaz, üreaz ve peroksidaz enzim aktiviteleri değerlendirilmiştir. Tanımlanan on bakteri türü arasında, %20,3'lük görülme sıklığı ile Pseudomonas aeruginosa en yüksek orana sahip olurken, %3,1'lik görülme sıklığı ile Streptococcus faecalis en düşük orana sahip olmuştur. Yedi mantar cinsi tanımlanmıştır. Bunlar arasında Aspergillus niger, Trichoderma spp. ve Penicillium spp. yer almaktadır. Çalışmada incelenen çöp depolama alanı topraklarında, analizler sonrasında enzim aktivitelerinde anlamlı düzeyde artış (P≤0,05) gözlenmiştir. Depolama alanı topraklarının peroksidaz ve katalaz aktiviteleri, kontrol toprak örneklerine kıyasla daha yüksek bulunmuştur. Çöp depolama alanı topraklarında belirlenen Na, Fe, Zn, Cu, Pb ve Cd içerikleri, kontrol topraklarında elde edilen değerlerden daha yüksek bulunmuştur. Buna karşın, kontrol topraklarının Ca, Mg ve K içerikleri, depolama alanı topraklarına göre anlamlı derecede daha yüksek olarak belirlenmiştir. İncelenen elementler arasında Fe, 33,57 ± 10,22 mg/kg değeri ile en yüksek konsantrasyona sahip olmuştur.
