Special Issue Information

Dear Colleagues,

Microalgae are tiny and diversity photoautotrophic organisms, which can be served or processed as nutriceutical, cosmetic, feed, biofertilizer, biofuels, and biomaterials. The microalgae industry has developed and expanded fast in recent decades due to the strong and multiple functions of microalgae. Photobioreactors (PBRs) are the key device for microalgae cultivation.The productivities of algal biomass and bioactive compounds are significantly influenced by the PBR design and operation. Thus, novel, efficient, and low-cost PBRs are urgently required to obtain high-quality and cost-effective algal biomass. In addition to traditional PBRs, such as raceway ponds, circle ponds, flat panels, and column and tubular bioreactors, special types including hybrid PBR, microalgal biofilm attached culture systems, inclined thin layer and membrane PBRs have recently developed fast, showing higher productivity or lower operation cost. They have great application potential especially in wastewater treatment, biofuel, and biofertilizer production.

This Special Issue welcomes recent reviews and original research manuscripts focusing on PBR design, modeling, and applications with innovations and new insights into microalgal bioreactor engineering and microalgae cultivation, aiming to upgrade PBR performance to accelerate the sustainable development of the microalgae industry.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Adding organic compounds to wastewater can improve the carbon/nitrogen ratio and benefit microalgae growth. We studied microalgal growth, nutrient removal and lipid accumulation of Chlorella pyrenoidosa cultured in a mixture of swine wastewater (SW) and furfural wastewater (FW). The mix ratio of SW:DFW [...] Read more.
Adding organic compounds to wastewater can improve the carbon/nitrogen ratio and benefit microalgae growth. We studied microalgal growth, nutrient removal and lipid accumulation of Chlorella pyrenoidosa cultured in a mixture of swine wastewater (SW) and furfural wastewater (FW). The mix ratio of SW:DFW (diluted furfural wastewater) had a significant effect on microalgae growth. As the mix ratio of SW:DFW decreased from 1:0.5 to 1:19, the maximum microalgal biomass increased, while the specific growth rate initially increased and then decreased. The efficiency of nutrient removal also depended on the mix ratio of wastewater. The highest chemical oxygen demand (COD) removal efficiency (57.30%) occurred at the mix ratio of SW:DFW = 1:3. The highest removal efficiencies of total phosphorous (TP) reached 61.93% when the mix ratio of SW:DFW was 1:9. Wastewater at the mix ratio of SW:DFW = 1:19 had a maximum lipid productivity of 49.48 mg L−1 d−1, which was 4.9 times higher than that at a mix ratio of SW:DFW = 1:0.5. These results showed that C. pyrenoidosa can be used to remove nutrients from mixed wastewater sources and simultaneously produce algal lipids. Full article
