“…Production of the same enzyme using Aspergillus ochraceus isolated from coffee pulp resulted in a specific activity of about 58 U/mg towards methyl ferulate. Moreover, this type C enzyme had a fivefold higher rate of synthesis of butyl caffeate compared to the type B enzyme (Romero Borbón et al, 2018).…”

“…Thus, isobutanol concentration can be enhanced if saccharification enzymes with a maximum activity at around pH 6.5 can be applied to SSF. Cellulase from Acetivibrio thermocellus [43], hemicellulase from Aspergillus ochraceus [44] and xylanase from B. subtilis [45] are known to show maximum activities at pH 6.5. To enhance isobutanol productivity, studies are planned on the production of isobutanol using batch fermentation, the aforementioned mutation to our isobutanol-producing E. coli strain and the use of the saccharification enzymes with maximum activity at around pH 6.5 in future studies.…”

Each year, near 40 million tons of banana peels are discarded around the world. This plant biomass could potentially be utilized for energy production. Simultaneous saccharification and fermentation (SSF) is an effective method for producing biofuels from plant biomasses. Since SSF with enzymatic hydrolysis and fermentation are performed simultaneously in the same reactor, the production process is simpler than most existing methods. Here, we describe isobutanol production using SSF with hydrothermally treated banana peel samples and an Escherichia coli strain able to utilize glucose and xylose to produce isobutanol. To enhance the glucose and xylose concentrations, the reaction conditions for the enzymatic hydrolysis of plant biomass using two kinds of saccharification enzymes were optimized, including the enzyme unit ratio, reaction temperature and sample gram. When the optimized conditions for enzymatic hydrolysis were applied to SSF, the glucose and xylose produced from the hydrothermally treated samples were consumed, producing isobutanol. Moreover, the isobutanol concentration increased with an increasing initial culture pH, reaching 1.27 g/L at pH 6.5, which was consistent with the optimal initial culture pH for isobutanol production by this E. coli strain. Taken together, these results indicate that the established method is potentially useful for industrial isobutanol production.

“…The enzymatic treatment involves feruloyl esterase enzyme (E.C. 3.1.1.73) (FAE), a key enzyme for the extraction of the ferulic acid from the plant cell wall [21][22][23][24][25][26][27] . The enzyme acts through delignification and depolymerization of polysaccharides and is able to hydrolyze the ester linkages between the arabinose sugar and ferulic acid [28][29][30][31][32][33] .…”

The ubiquitous compound 4-Hydroxy-3-methoxy cinnamic acid, also known as ferulic acid, constitute. A bioactive ingredient of many food that may offer a potential therapeutic effects useful in the treatment of cancer, diabetes, lung and cardiovascular disease. It is also effective against the disorders relative to oxidative stress, including certain neurodegenerative diseases. Ferulic acid is widely distributed in plants in either free or conjugated forms. Overall the pharmaceutical potential of ferulic acid can be attributed to its ability in scavenging free radicals. In recent years, it is also known to inhibit HNG-CoA reductase and activate glucokinase, thus contributing to the reduction of hypercholesterolemia and hyperglycemia. This review discusses the different properties of ferulic acid, establishing a relationship to several biological activities. FA is also used in a substantial amount in the food and cosmetic industries. So also, in recent years, it has been used as a cross-linking agent to manufacture edible food films. The review also discusses compound distribution, metabolism, and physiological role uses in the production of vanillin. INTRODUCTION:Ferulic acid (FA) is the most important hydroxycinnamic acid found abundantly in plant tissue 1-3 . In the plants, FA is rarely found in the free form. It is mainly found as an ester crosslinked with polysaccharides in the cell wall 4-5 . Ferulic acid was first isolated and purified from the plant Ferula foetida in 1866 and was chemically synthesized in 1925 [6][7][8] . FA is basically a phenylpropanoid and exists as a crystalline solid. FA also play a functional role in the structural integrity of the cell wall as it is associated with cellulose, hemicellulose, and lignin 9, 10 . Polyphenolic acids are secondary metabolites of a varying chemical structures and biological properties.
