The effect of ozone and ozone plus a biological catalyst (catalase) on the degradation processes of Reactive Black 5 was investigated. The ozonation process was carried out in a laboratory-scale batch reactor with a volume of 500 ml. Chemical oxygen demand (COD), pH, color removal and the BOD 5 /COD ratio were measured during the process. At the first stage, only ozonation was performed, at the second stage, ozonation plus NaCl and Na 2 CO 3 , and at the third stage, ozonation plus catalase enzyme were used. As a result of the oxidation of Reactive Black 5 with only ozone and ozone plus textile auxiliaries, chemical oxygen demand (COD) removal was 34% and 19%, respectively. COD removal efficiency was 43% when 10 ml of catalase was added to the ozone reactor. Carbonate and salt have a negative effect on the oxidation of reactive Black 5 with ozone. Reactive Black 5 was degraded into sub-components, and the biodegradability of the wastewater increased. The pH value decreased from 3.3 down to 1.6, which showed that organic acids were formed as a result of degradation. The use of enzymes in combination with ozonation shows that Reactive Black5 can rapidly convert into the intermediate within the 270-min ozonation time (BOD 5 /COD = 0.46). COD removal was not as high as color removal efficiency. This may have resulted from the formation of colorless oxidation products. The significant increase in biodegradability after ozonation in the presence of the catalyst may also be seen as a reduction of toxic intermediates.

Evaluation of antioxidant peptides generated from Jiuzao (residue after Baijiu distillation) protein hydrolysates and their effect of enhancing healthy value of Chinese Baijiu

BACKGROUND: Jiuzao is the residue after Bajiu distillation which is usually used as forage for livestock. However, it is not fully utilized yet considering the content of protein remained. The present study aimed to isolate antioxidant peptides from Jiuzao protein hydrolysates, then add these peptides into Baijiu product to enhance the healthy value of Baiju. Meanwhile environmental pollution caused by massive Jiuzao can be mitigated indirectly. RESULTS: Four peptides Ala-Tyr-Ile(Leu) (AYI(L)) andAsp-Arg-Glu-Ile(Leu) (DREI(L)) were identified from Jiuzao protein hydrolysates, the extraction contents of AYI + AYL and DREI + DREL were 896.10 and 110.51 mg kg −1 Jiuzao, respectively. On the one hand, antioxidant activities of these peptides were investigated. For in vitro antioxidant assays, AYI, AYL and DREI exhibited strong capacities in oxygen radical absorbance capacity (ORAC) assay. Furthermore, three levels of four peptides were assessed by 2,2'-azobis(2-methylpropanimidamidine) (AAPH)-induced HepG2 cells model. The results showed that these peptides exerted a degree of antioxidant activities in cells. Meanwhile, selected peptides concentrations according to cell assays remined at effective doses after in vitro digestion. On the other hand, the influence of these four peptides on the characteristic aroma compounds in Baijiu was studied. Most characteristic aroma compounds releases were increased with the addition of peptides.CONCLUSION: In the study, antioxidant activities of peptides were evaluated, the feasibility of utilizing Jiuzao protein hydrolysates to obtain beneficial peptides was also proved. Healthy effect of Baijiu or other food can be increased by adding these functional substances. The findings might contribute to food application and Baijiu industries.

“…For CAT, the reaction involves the disproportionation of H 2 O 2 to water and oxygen. CAT is known to have one of the highest enzymatic turnover rates with the capability to decompose more than one million H 2 O 2 molecules per molecule of enzyme . HRP catalyzes the H 2 O 2 ‐mediated oxidation of various substrates and exhibits CAT‐like production of oxygen if H 2 O 2 is available as a unique substrate in neutral solution .…”

Enzyme‐powered micro‐ and nanomotors are tiny devices inspired by nature that utilize enzyme‐triggered chemical conversion to release energy stored in the chemical bonds of a substrate (fuel) to actuate it into active motion. Compared with conventional chemical micro‐/nanomotors, these devices are particularly attractive because they self‐propel by utilizing biocompatible fuels, such as glucose, urea, glycerides, and peptides. They have been designed with functional material constituents to efficiently perform tasks related to active targeting, drug delivery and release, biosensing, water remediation, and environmental monitoring. Because only a small number of enzymes have been exploited as bioengines to date, a new generation of multifunctional, enzyme‐powered nanorobots will emerge in the near future to selectively search for and utilize water contaminants or disease‐related metabolites as fuels. This Minireview highlights recent progress in enzyme‐powered micro‐ and nanomachines.
