The aim of this study was to determine the effect differences addition culture medium concentrations on growth microalgae type Chlorella sp. Samples were obtained from Center for Brackish Water Cultivation Fisheries (BBPBAP), Jepara. This research conducted at Laboratory Nutrition and Natural Feed Sorong Marine Polytechnic with an experimental method using four treatments walne medium, there A ...

The use of pesticides in agriculture has ensured the production different crops. However, have become an emerging public health problem for Latin American countries due to their excessive use, inadequate application, toxic characteristics, and minimal residue control. current project evaluates ability two strains algae (Chlorella Scenedesmus sp.) one cyanobacteria (Hapalosyphon remove excess ot...

In photosynthesis, a very small amount of the solar energy absorbed is transformed into chemical energy, while the rest is wasted as heat and fluorescence. This excess energy can be harvested through biophotovoltaic platforms to generate electrical energy. In this study, algal biofilms formed on ITO anodes were investigated for use in the algal biophotovoltaic platforms. Sixteen algal strains, ...

Currently microalgae are considered as an efficient biological producer of oil.Present study was conducted to explore the lipid yield percentage three microalgal strains Chlorellasp., Oedogonium sp. and Spirogyra Bligh Dyer, Soxhlet, Folch Microwave assistedextraction methods were employed for oil extraction. It observed that Dyer method withChloroform-methanol (1:2, v/v) gave maximum extractio...

Although single-species laboratory toxicity tests with microalgae are sensitive and highly reproducible, they lack environmental realism. Interactions between algae and their associated bacteria, either in the plankton or in biofilms, may alter algal sensitivity to contaminants, which are not mimicked in laboratory toxicity tests. This study investigated the effects of simple algal-bacterial re...

One of the biggest global challenges in mining industry is managing risks associated with contamination by potentially toxic elements (PTEs) resulting from their activity. The oxidation sulfides main cause polluted mine drainage through leaching PTEs waste and galleries to water systems. Mine can be highly acidic often has a high concentration PTEs, particularly arsenic, one environment’s most ...
