The long-term effects of hexavalent chromium on anaerobic ammonium oxidation process: Performance inhibition, hexavalent chromium reduction and unexpected nitrite oxidation.
TLDR
The results showed Anammox performance was not affected at low Cr(VI) concentration, but was severely inhibited at 0.8 mg L-1, and microbial community showed no enrichment of Cr( VI) reducing bacteria and other nitrogen transformation-related bacteria.About:

Quantitative determination of cavitation formation and sludge flotation in Anammox granules by using a new diffusion-reaction integrated mathematical model.
TL;DR: For quantitative evaluation of the Anammox granules flotation in upflow reactors, an integrated mathematical model was formulated based on the principles that the limitation of substrate diffusion would result in bacterial starvation, lysis and subsequently aiding the formation of cavitation in the inner zone of granules.

Deciphering the microbial and genetic responses of anammox biogranules to the single and joint stress of zinc and tetracycline.
TL;DR: The findings suggested that anammox could be inhibited by metals and antibiotics, but it has the potential to remove nitrogen from wastewaters containing both of them within the concentration threshold.

Visible-light-driven zeolite imidazolate frameworks-8@ZnO composite for heavy metal treatment
TL;DR: Zhang et al. as discussed by the authors developed a facile strategy for constructing ZnO sheets with defective zeolite imidazolate frameworks-8 (ZIF-8) to form visible-light-driven Zif-8@ZnO composite for efficient photoreduction of hexavalent chromium Cr(VI).

Simultaneous Cr(VI) bio-reduction and methane production by anaerobic granular sludge.
TL;DR: Methane production by anaerobic granular sludge was improved by the addition of Cr(VI) at a concentration lower than 500 µg·L-1, and Trichoccus accelerated the degradation of organic substances to generate acetates with a low Cr( VI) concentration, thereby enhancing methane production by acetotrophic methanogens.

TL;DR: In this article, a Cr(VI)-reducing bacteria (Pseudochrobactrum saccharolyticum LY10) was selected to simulate the biofilm grown in unsaturated habitats containing Cr (VI) and the X-ray fluorescence and absorption methods were used to characterize the temporal and spatial distributions of metal elements in the unsaturated biofilms.
