In this work, cattle manure was diluted and pre-treated with biomass ash to yield a liquid fraction solid precipitate. Microalgae grown in the fraction, batch semi-continuous mode, achieved maximum productivities of 522.9 554.3 mg L−1 day−1 (12 days) for Chlorella protothecoides Tetradesmus obliquus, respectively. Nutrient removal efficiency highest semicontinuous mode replacement 10% reactor v...

Some vegetables have the ability to accumulate cadmium (Cd)at levels that are toxic most other plants. The objective of thisstudy was evaluate Cd accumulation and its effects on edible vegetables.
