Particulate matters critically prevented ARB from generating current in anode biofilm, showing 76% reduction of current density. Direct utilization of raw sewage improved current density up to 20%, indicating the significance of fermenters and their syntrophy with ARB.

“First time, ferulic acid (4-hydroxy-3-methoxycinnamic acid, FA) was isolated from Ferula foetida for its structure determination, and its name was based on the botanical name of plant [27]. In 1925, FA was chemically synthesized and structurally confirmed by spectroscopic techniques, depicted the presence of an unsaturated side chain in FA, and also existence of both cis and trans

isomeric forms [14] and [56]. The double bond present in the side chain is subjected to cis–trans isomerization ( Fig. 1), and the resonance stabilized phenoxy radical accounts for its effective antioxidant activity. It catalyzes the stable phenoxy radical formation upon absorption of ultra-violet light, which gives the strength to FA for terminating buy Dapagliflozin free radical chain reactions. FA is an enormously copious and almost ubiquitous phytochemical phenolic derivative of cinnamic acid, present in plant cell wall components as covalent side chains [66]. Collectively with dihydroferulic acid, it is the component of lignocelluloses, where it confers rigidity to the cell wall by making the crosslink between polysaccharides and lignin. It has been found that FA is linked with a variety of carbohydrates as glycosidic conjugates, different esters and amides with a broad range of natural products [73]. It makes esters by binding with oxyclozanide a variety of molecules such as polysaccharides,

long chain alcohols, various sterols of plant, tetra-hydroisoquinoline-monoterpene glucoside, a cyanogenetic glycoside and an amino-hydroxy-cyclopentenone, flavonoids and different types of hydroxycarboxylic acids including gluconic, tartaric, malic, hydroxycitric, tartronic, quinic, and hydroxy fatty acids [9], [17], [24] and [25]. The aim of this review is to provide the organized outline about natural sources, metabolism, and different applications of FA in biomedical, pharmaceutical, food, cosmetic and other industries, which will provide vast information to a wide range of researchers, working on the different applications of natural products. FA is commonly found in commelinid plants (rice, wheat, oats, and pineapple), grasses, grains, vegetables, flowers, fruits, leaves, beans, seeds of coffee, artichoke, peanut and nuts [8], [47], [48], [49], [72] and [85].
