Biodegradation of dairy effluent by using microbial isolates obtained from activated sludge

Use of Bacteria and Yeast Strains for Dairy Wastewater Treatment

“…To study the biodegradation efficiency of the microbial and yeast isolates, biomass of actively growing cells was prepared as described by Porwal et al [6]. Each bacterial strain was inoculated to 50 ml MRS broth medium and incubated at 37°C for 24 hours with 150 rpm agitation speed.…”

“…The comparison of the COD removal efficiency of single strains to mixed culture shows that, in the present study, the COD was reduced to 75.8% with bacterial consortium with an inoculums rate of 1%, however, the reduction efficiency of single cultures were 71.6% and 60.8%, respectively, for Lactobacillus plantarum and Lactobacillus casei at the same inoculums rate (1% (v/v)). Porwal et al [6] reported that a mixed culture of bacteria and yeast isolates has the best reduction efficiency of the effluent than single cultures with COD reduction rate of 86%, 73% and 66%, respectively, for mixed culture, yeast isolate and bacteria isolate. Chatterjee and Pugaht [15] had also reported 67.1% and 48.3% reduction in COD of dairy wastewater using a mixed culture with the use of two bacterial strains namely Neisseria sp.…”

Humic acid and trihalomethane breakdown with potential by-product formations for atmospheric air plasma water treatment

“…Biological processes, including the use of bio-filters may lead to the accumulation of suspended solids and release of bacteria [20]. Separation technologies such as biofilms and membrane filtration may be limited due to fouling [21]. Ozone's efficacy for humic substance breakdown in water has been demonstrated, however the process may result in the formation of brominated by-products [22].…”

Süt Endüstrisi Atıksuyunun Biyometanizayon Potansiyelinin İncelenmesi

“…Yenilenebilir enerji kaynakları; hidrolik, rüzgar, güneş, jeotermal, biyokütle, biyogaz (çöp gazı dahil), dalga,akıntı enerjisi ve gel git gibi fosil olmayan enerji kaynaklarıdır. Biyokütle, yeşil bitkilerin güneş enerjisini fotosentez yoluyla kimyasal enerjiye dönüştürerek depolaması sonucu meydana gelen ve canlı organizmaların kökeni olarak ortaya çıkan organik madde kaynakları olarak tanımlanmaktadır [2,3,4]. AB'nin yıllık toplam enerji tüketiminin yaklaşık %6'sı biyokütleden sağlanmaktadır.…”
