TL;DR: The developed two-step process provides a feasible strategy for commercial production of ketocarotenoids by the green microalga, Chlorococcum sp.
Abstract: The production of ketocarotenoids (KCs) from Chlorococcum sp. strain MA-1was investigated by a two-step process. In the first step, 18 g biomass l–1 was achieved by feeding glucose to the heterotrophic cultures; in the second step, the high-density cultures were treated with light illumination or chemical stress in dark, respectively, to induce KC synthesis. Light-treated cultures could produce 103 mg total KCs l–1 and 32 mg astaxanthin l–1, three times higher than those from chemical-treated cultures, in the 10 days of induction. The percentages of individual KCs (hydroxyechinenone, canthaxanthin, adonirubin and astaxanthin) in the total KCs were not markedly influenced by the different stress conditions. The developed two-step process provides a feasible strategy for commercial production of ketocarotenoids by the green microalga, Chlorococcum sp. strain MA-1.

TL;DR: A one-pot approach to produce HMF from aquatic microalgae with a yield up to 48.0% under mild reaction conditions over the commercial cheap H-ZSM-5 catalyst demonstrated excellent stability, and a slight loss of its activity can be easily recovered by simple calcination treatment.

TL;DR: In this article, the flocculation efficacy of different inorganic and organic amendments was evaluated on various microalgae genera and showed that widely available cheaper biopolymers such as rice starch, maize, and potato starch can be promising flocculants due to their better harvesting efficiency and low price.
Abstract: Cost-efficient harvesting of microalgae is a major challenge due to their small size and often low concentration in the culture medium. The flocculation efficacy of different inorganic and organic amendments was evaluated on various microalgae genera—one strain each belonging to Chlamydomonas, Chlorococcum, two of Botryococcus, and of Chlorella. An improvised medium comprising of commercial grade urea, single super phosphate, and muriate of potash was used to grow the microalgae for flocculation experiments. High pH induced increased flocculation efficiency (72–76 %) in selected microalgal strains. Ferric chloride was found to be the most efficient for most of the microalgal strains, while maize starch and rice starch proved superior for Chlorella sp. MCC6 and Botryococcus sp. MCC32. Although the highest flocculation efficiency was obtained with inorganic flocculant, i.e., ferric chloride (87.3 %) with Botryococcus MCC31, this was comparable with rice starch (86.8 %) for Botryococcus MCC32. This study showed that widely available cheaper biopolymers such as rice starch, maize, and potato starch can be promising flocculants due to their better harvesting efficiency (>80 %) and low price, thereby contributing to economical production of biodiesel from algae.

TL;DR: The hydrolysis products of fenamiphos, FSOP and FSO(2)P are more toxic to both fresh water and soil algae than their parent chemicals, and further fenAMiphos can be transformed and bioconcentrated by these algae.
