Soil application of biosolids as an organic fertiliser continues to be a cost-effective way to
beneficially utilise its carbon and nutrient contents to maintain soil fertility. However, ongoing …

The coexistence of algae and bacteria in nature dates back to the very early stages when life
came into existence. The interaction between algae and bacteria plays an important role in …

Anoxygenic phototrophic bacteria (APB) are a phylogenetically diverse group of organisms
that can harness solar energy for their growth and metabolism. These bacteria vary broadly …

Sustainable development is driving a rapid focus shift in the wastewater and organic waste
treatment sectors, from a “removal and disposal” approach towards the recovery and reuse …

The use of chemical fertilizers in agriculture poses problems for the health of the soil and the
environment. Biofertilizers and microalgal biostimulants emerge as an alternative to reduce …

Food waste can be used via anaerobic digestion (AD) to produce biogas. The liquid by-
product (digestate) contains nitrogen (mainly as ammonium) which is susceptible to N loss …

The use of microalgae for nutrient recovery from wastewater and subsequent conversion of
the harvested biomass into fertilizers offers a sustainable approach towards creating a …

Phototrophic microorganisms (microbial phototrophs) use light as an energy source to carry
out various metabolic processes producing biomaterials and bioenergy and supporting their …

The continuous growth of the world population has imposed major challenges on
agriculture. Consequently, farmers generalized the overuse of synthetic fertilizers and …

Within the biorefinery concept, microalgal cultivation has potential as one component of the
wastewater treatment toolkit for anaerobic digestates. Recovering nutrients from digestate …
