Producing a biofertilizer with microalgae and wastewater

Producing a biofertilizer with microalgae and wastewater

The high concentration of nutrients in wastewaters and in effluents of agro-industrial processes, particularly total N and P, is an environmental problem, and requires costly chemical-based treatments to remove them during wastewater treatment. The ability of microalgae to effectively grow in nutrient-rich…

A novel algae strategy for arsenic poisoning

A novel algae strategy for arsenic poisoning

The World Health Organization (WHO) estimates over 200 million people worldwide are exposed to arsenic concentrations in drinking water that exceed the guideline limit of 10 µg/L. This threshold may also be expressed as 10 parts per billion (ppb). The majority of arsenic exposure lies in southern Asian countries…

Can algae save children from heavy metals poisoning?

Can algae save children from heavy metals poisoning?

Approximately half a million U.S. children under five years of age have been tested with blood lead levels exceeding five micrograms per deciliter (µg/dL), the reference level at which CDC recommends public health actions be initiated. The number of children and adults at risk from the broader array of heavy metals…

Isolating Algal Species

Isolating Algal Species

Dr. Brad Elder’s algae research team at Nebraska’s Doane College created this video, featuring undergraduate researchers Ryan Corrigan and Jeff Hawken, to illustrate a method of isolating different algal species from large diverse populations of algae. The growth medium resists bacteria and fungal growth…

Researching the enormous strength of diatoms

Lori Dajose writes in PhysOrg that researchers in the lab of Julia Greer, professor of materials science and mechanics in Caltech’s Division of Engineering and Applied Science, have recently found that diatoms have the highest specific strength — the strength at which a structure breaks with respect to its density…

Algae Fuels boosted by NREL process

Algae Fuels boosted by NREL process

A new biorefinery process developed by scientists at the Energy Department’s National Renewable Energy Laboratory (NREL) has proven to be significantly more effective at producing ethanol from algae than previous research. The process, dubbed Combined Algal Processing (CAP), is detailed in a new paper by NREL’s…

An algae solution for Flint, Michigan’s Lead Poisoning? Part 2

An algae solution for Flint, Michigan’s Lead Poisoning? Part 2

The best way to lower an elevated blood lead level is to prevent continued exposure to lead. Flint children are now receiving bottled and other sources of clean water, which stops the bioaccumulation of lead in their bodies. However, many children are left with dangerously high levels of lead in the brains…
