TL;DR: This review summarizes the current technology status and challenges, economics, novel strategies for production of bacterial pigments and metabolic engineering of bacteria with a focus on applications of bacterial Pigments in food industry, pharmaceutical industry, dyeing as well as on other applications.

TL;DR: By virtue of their hydrogen donating ability, phenolic compounds with multiple hydroxyl groups such as protocatechuic acid, pyrogallol, caffeic Acid, gallic acid and propyl gallate exhibited higher free radical scavenging activity especially against DPPH• and O2•-.

TL;DR: In this article, the authors demonstrated the potential of using pineapple waste biomass as cheap and efficient raw materials to produce activated carbon for dye removal from wastewaters, which was evaluated for its dye removal efficiency using methylene blue (MB) taking into consideration the following parameters; contact time, initial concentration of MB and adsorbent dosage.

TL;DR: Possible application of a locally isolated environmental isolate, Acinetobacter haemolyticus to remediate Cr(VI) contamination in water system was demonstrated and the presence of electron-dense particles in the cytoplasmic region of the bacteria suggested deposition of chromium in the cells.

TL;DR: Pyroligneous acid finds application in diverse areas, as antioxidant, antimicrobial, antiinflammatory, plant growth stimulator, coagulant for natural rubber, and termiticidal and pesticidal agent; is a source for valuable chemicals; and imparts a smoky flavor for food.
