“…The action of oxidoreductase on 2‐amino‐3‐(2‐hydroxyphenyl) propanoic acid broke it into 2‐amino‐3‐(2,6‐dihydroxyphenyl) propanoic acid with the reduction of NADPH to NADP. The final breakdown product 2‐amino‐3‐phenylpropanoic acid (phenylalanine) was mediated by the dehydrogenase with the removal of OH group, NAD+, or NADP+ as a receptor (Ahn & Obendorf, 2007) (Figure 2).…”

Reactive dyes are pernicious pollutants in textile effluent, which are to be treated passably before discharging into the environment. In the present study, a potential dye degrading bacterial strain Pseudomonas guariconensis was isolated from paddy rhizosphere and was characterized by 16S rRNA gene sequencing. The biodegradation ability of the strain was evaluated by time‐based study with immobilized bacterial cells in calcium alginate biocarrier matrix and also with free cells. The results indicated that the strain exhibited maximum degradation of 91% when immobilized in the biocarrier matrix. The enzymatic study revealed the production of oxidoreductase enzymes. The degraded products were identified as 2‐amino‐3‐phenylpropanoic acid and benzoquinone by gas chromatography–mass spectroscopy (GC‐MS) analysis, and a degradative pathway was derived based on the enzymatic profile. A packed bed column was designed using P. guariconensis VITSAJ5 immobilized in calcium alginate beads as a biosorbent for the removal of Reactive Red 120. The immobilized bacterial cells exhibited 87% uptake of RR120, whereas the nonimmobilized bacterial cells exhibited a maximum uptake of 37%. The phytotoxicity analysis by seed germination assay revealed an enhanced plumule and radicle length, indicating the nontoxic byproducts after the treatment of Reactive Red 120 by VITSAJ5 compared to the untreated Reactive Red 120 solution. Practitioner points Current study is the first report on Pseudomonas guariconensis capable of degrading reactive dyes (Reactive Red 120) It was observed that the degradation potential was maximum when cells were immobilized with Ca‐Ag biocarrier matrix Breakdown metabolism of Reactive Red 120 was derived through pathway prediction Employing immobilized bacteria in a packed bed column found to possess a prominent biosorption ability on the matrix enhancing the degradation process Toxic reactive dye was converted into nontoxic compounds, evidenced by phytotoxicity studies

“…Between the thermal and H2O2/UV/O2 degradation treatment, H 2 O 2 /UV/O 2 treatment is intended to induce a stronger oxidative environment than the thermal treatment by the production and reaction of hydroxyl radicals from H 2 O 2 (Ahn & Obendorf, 2007). The present data which showed that dihydroberberine was detected only in the 6 hour sample of H2O2/UV/O2 degradation while it was detected throughout the thermal degradation times clearly reflects the difference in the magnitude of oxidative strength between the two degradation conditions.…”

“…The data from such experiment can then be used as the pool of comparative standards for investigation the dye in archaeological textiles. Under such premise, previous researches on alizarin and curcumin have been successfully carried out (Ahn & Obendorf, 2004, 2007. And as part of the continuing effort for the identification of dye in archaeological textiles, the purpose of the present research was to examine the degradation behavior of berberine using gas chromatography mass spectrometry (GC-MS).…”

“…Following the previous method of analysis (Ahn & Obendorf, 2004, 2007, the thermal degradation in 100 o C oven temperature was chosen based on the researches simulating natural ageing of dyed textiles via accelerated thermal treatment (Brushwood, 1988;Needles et al, 1986;Needles & Nowak, 1989). Needles et al (1986) examined burial-induced color and strength changes in wool and silk fabrics and found that alizarin dyed fabrics became extremely dark and changed shade toward purple.…”

The degradation behavior of berberine is examined using GC-MS to select the fingerprint products that can be used to identify berberine dye in badly faded archaeological textiles. A total of 100 o C thermal and H2O2/UV/O2 degradation systems were used to degrade berberine chloride 0.1% solution up to 408 hours. The samples were analyzed using the GC-MS. Dihydroberberine, 2-pteridinamine, 6,7-dimethyl-N-[(trimethylsilyl)oxy]-, and 8-methoxy-11-[3-methylbutyl]-11H-indolo[3,2-c]-quinoline, 5-oxide were detected as the major products of thermal degradation and identified as the fingerprint products for berberine dye at the early stage of degradation. Isobenzofuran-1,3-dione,4,5-dimethoxy-, 9H-fluorene,3,6-bis(2-hydroxyethyl)-, 1,3-dioxolo[4,5-g]isoquinolin-5(6H)-one,7,8-dihydro-, and 3-tert-butyl-4-hydroxyanisole were detected as the major products generated by the H2O2/UV/O2 degradation and identified as the fingerprint products for berberine dye under severe degradation conditions.

“…That compound is consider one of the principal colouring components of curcumin. Curcumin is a colouring substance obtained by solvent extraction of tumeric and it is an orange-yellow crystalline powder (Ahn and Kay, 2007). Also, limonine, heptanol, caryophyllene, betasesquiphellandrene and pyridine were terpenoids and diarylheptanoid detected under the GC-MS instrumental conditions with concentrations of 0.5, 0.1, 0.4, 2.4 and 3.5, respectively.…”

In the present study, the anthocyanins and carotenoids contents in some plants, herbs and either vegetables or fruit wastes were considered. Anthocyanins were extracted from red beet roots (Beta vulgaris L.), dark roselle petals (Hibiscus sabdariffa L.) and eggplant peels (Solanum melongena). Meanwhile carotenoids were extracted from spinach leaves (Spinacia oleracea), tumeric (Curcuma Longa Zingibaraceae) and tangerine peels (C. reticulata Magnoliopsida). These extracts were examined as antimicrobial agents against Staphylococcus aureus, Bacillus subtilis, Salmonella sp., E.coli, Trichoderma viride and Candida utilis. The anthocyanins and carotenoids fractions in the extracts were quantitatively and qualitatively determined by HPLC and GC-MS and revealed the presence of great numbers of flavonoids and terpenoids compounds which have the ability to act as antimicrobial agents. Roselle extract proved the superiority over the other extracts against the tested microorganisms in exception with Staphylococcus aureus, whereas, the eggplant peels anthocyanins had the highest antibacterial action against it. However, red beet roots extract had negative effect against Trichoderma viride, Candida utilis and Bacillus subtilis. Similar effect of the inhibition zone values were observed between spinach and tangerine peels carotenoids toward the Trichoderma viride and Salmonella sp. Tangerine peels carotenoids were better than tumeric carotenoids toward Candida utilis, Bacillus subtilis and Salmonella sp., while tumeric carotenoids were better than both tangerine peels and spinach carotenoids toward Trichoderma viride, Staphylococcus aureus and E.coli. Red beet roots anthocyanins showed inhibitory effect higher than that of spinach carotenoids against Staphylococcus aureus, Salmonella sp and E.coli. Similar effect was also recorded with tumeric carotenoids and roselle petals anthocyanins against Trichoderma viride. Also, nearlly inhibitory effect found by tumeric carotenoids and eggplant peels anthocyanins against Bacillus subtilis. Obtained data suggest the possibility to use such extracts in food processing to control pathogens and for food preservation as well.
