Seasonal Dynamics of Periphyton in a Large Tropical Lake
Tropical aquatic systems are generally assumed to have little seasonality in productivity patterns. However, this study indicated that there was substantial seasonal variation in epilithic productivity and biomass in tropical Lake Tanganyika, due primarily to seasonal patterns in lake hydrodynamics that influence nutrient availability. Although they support much of the lake’s biological ...

Biosorption of methylene blue by nonliving biomass of the brown macroalga Sargassum hemiphyllum
The ability of Sargassum hemiphyllum to remove methylene blue (MB) from aqueous solution was evaluated. Batch experiments were conducted to examine the effects of parameters such as initial pH, contact time, biomass dose and initial dye concentration on adsorption capacity. S. hemiphyllum before and after MB adsorption was characterized by Fourier transform infrared spectroscopy (FT-IR), ...

Cr(III) uptake by marine algal biomass: equilibrium and kinetics
In this work, biosorption of Cr(III) by the marine brown algae Sargassum muticum was studied in a batch system. Kinetics and equilibrium experiments were conducted at different pH. Equilibrium data are well described by the Langmuir and Langmuir-Freundlich isotherms. The two mass transfer models give comparable results, but they did not provide a perfect representation of the sorption data. ...

The effects of Parachlorella kessleri cultivation on brewery wastewater
Bioindustrial wastewaters, often characterised by high carbon and nitrogen contents, have shown promise as a valuable resource for the cultivation of beneficial microorganisms. The purpose of this study was to assess if Parachlorella kessleri could utilise brewery wastewater (Br WW) for growth and production of metabolites. P. kessleri was cultivated on different concentrations of Br WW over ...

Pretreatment of brewery effluent to cultivate Spirulina sp. for nutrients removal and biomass production
Due to the low concentration of nitrate and high contents of organics, brewery effluent was not suitable for the cultivation of Spirulina sp. This work changed the nutrient profile of brewery effluent effectively by dilution, addition of nitrate, and anaerobic digestion. The result showed that the optimum dilution rate and NaNO3 addition for brewery effluent were 20% and 0.5 g/L, ...

Advancements In Algal Biomass Yield, Phase 2 Funding Announced
On January 15, 2016, the U.S. Department of Energy (DOE) announced up to $15 million in funding for the development of algal biofuel intermediate technologies. Technology applicants should be likely to produce 3,700 gallons of algal biofuel intermediate per acre per year on an annualized average basis in an outdoor test environment by 2020. Applicants should also address a topic area within the ...

Factors influencing flamingo (Phoenicopterus roseuis) distribution in the Pulicat Lagoon ecosystem, India
The shallow (1.5 m) Pulicat Lagoon in India supports a variety of migratory birds (125 species), especially flamingos and storks. Flamingo populations in this area are dominated by Phoenicopterus roseuis, and they are densely distributed in shallow areas and fringes of the lake where the water level is below 40 cm. Eighteen flamingo groups are distributed around the lagoon with ~750 individuals ...

Cultivation of an Arthrospira platensis with digested piggery wastewater
An Arthrospira platensis strain ZJWST-S1 was isolated in Jiaxing City, China, which proved able to proliferate quickly in undiluted digested piggery wastewater (DPW), and the protein content in the algal biomass was high. Single factor experiments showed that the strain was able to quickly grow in a Zarrouk medium as the dosage of sodium bicarbonate, nitrate-nitrogen and phosphate-phosphorus ...

Effects of pulsed atrazine exposures on autotrophic community structure, biomass, and production in field‐based stream mesocosms
We performed a multiple‐pulsed atrazine experiment to measure responses of autotrophic endpoints in outdoor stream mesocosms. The experiment was designed to synthetically simulate worst‐case atrazine chemographs from streams in agricultural catchments to achieve 60‐day mean concentrations of 0 (control), 10, 20, and 30 µg/L, respectively. We dosed triplicate streams with pulses of 0, 50, 100, ...

Interest in DOE Algae Biomass Program/BETO technologies diminishes because they have proven to not be scalable outside the lab in demonstration or pilot tests.
After over 10 years of attempts at collaboration between the DOE Algae Biomass Program/BETO, university algae researchers and commercial algae producers over highly advertised pay-to-play taxpayer funded technologies, NAA and its algaepreneurs have no further interest. Why? On information and belief, many of these hyped technologies have not been able to be proven outside the lab in demo and ...

Algae biomass cultivation in nitrogen rich biogas digestate
Because microalgae are known for quick biomass growth and nutrient uptake, there has been much interest in their use in research on wastewater treatment methods. While many studies have concentrated on the algal treatment of wastewaters with low to medium ammonium concentrations, there are several liquid waste streams with high ammonium concentrations that microalgae could potentially treat. ...
