“…In this study, all bacterial and fungi species had a growth ability and are expected to be detoxification tools of potassium dichromate that blended with GA and PVA or both which leads to reduce the high absorption rate of chromium ion by animal, plant, and algae cells in the soil and enhancing the biodegradation of bioplastic membranes [25]. No yeast cells found in our samples and this is not agree with Jadhav et al [33] who proved that yeast are capable to reduce the toxicity of the dye in the environment to the permissible limit of discharge.…”

“…Moreover, the microbial communities of the bioplastic blends, namely (chromated GA/PVA=1:1), (chromated GA/PVA=1:0.75), (chromated GA/PVA=0.5) and (GA/PVA=1:0.25) contained Bacillus spp [25,45,46,49,53], Pseudomonas spp [27,31,47,48,50], Aspergillus spp, Rhizorpous spp, and Penicillium spp. [33]. It is worth to mention that Pseudomonas spp.…”

“…The buried chromated pure PVA membrane, the dominant species were Bacillus spp [25,45,46,47,48,49], Pseudomonas spp [27,31,50,47,48], Aspergillus spp [51] and Penicillium spp [27,47]. In addition, for the buried GA, the major species were Bacillus spp [6,12,45], Penicillium spp, Aspergillus spp, Rhizorpous spp, [6,33,34]. This results agree with Coleman and Paran [52] who concluded that Gram-negative chromium reducing-bacteria tend to be more sensitive to chromium ion, while Gram positive bacteria are significantly tolerant to chromate ion toxicity even at relatively high concentration of the ion [25,52].…”

“…[30,31], Staphylococcus aureus IFR-2, and Pediococcus pentosaceus IFR-3 [32], are the most bacterial strains having the abilities for detoxification of potassium dichromate, while Penicillium sp., Rhizopus sp., Aspergillus sp. were the most strains of fungi possessing this ability [33,34].…”

Gum Arabic (GA) collected from Acacia senegal trees was used with polyvinyl alcohol (PVA) to prepare of a series of biodegradable membranes doped and non-doped with potassium dichromate (K 2 Cr 2 O 7 ). Adding the K 2 Cr 2 O 7 to the GA/PVA blends slightly decreased their crystallinity index (CI) by about 2 %. Increasing the PVA concentration in the chromated GA/PVA blends was responsible for increasing the CI. Adding the K 2 Cr 2 O 7 to the pure GA solution modified its differential thermal behavior whereby the exothermic reactions occurred between 321°C and 433°C were disappeared. The K 2 Cr 2 O 7 increased the heat change drastically for all the bioplastic blends with the highest increase for the pure GA. Adding K 2 Cr 2 O 7 to the pure PVA increased the nanometric particle size (NPS) significantly. Increasing the PVA concentration in a blend had a greater effect than did the K 2 Cr 2 O 7 on the NPS. The buried bioplastic membranes in the control soil had different count and species of microbial communities. The numbers of bacteria and fungi in the initial soil sample were lower than those for chromated GA membranes and were greater than those for the chromated PVA. All bacterial and fungi species had growth ability and are expected to be detoxification tools of chromium ion-doped blends of GA and PVA leading to a green environment.

“…Even very small quantities of these dyes in aqueous environments can significantly affect the transparency and quality of bodies of water, leading to water pollution. Chemical dyes absorb and reflect sunlight that enters the water, and the absorption of light decreases algal photosynthesis and can disrupt the food chain (Indrani et al 2016;Pirsaheb et al 2016).…”

Water pollution due to the effluents from textile industries causes serious concern around the world. During the coloration process, the excess synthetic dyes are discharged into the wastewater stream. In the present research, kenaf core fiber (KCF) residue was chemically modified with (3-chloro-2-hydroxypropyl) trimethylammonium chloride (CHPTAC) to alter the surface properties and increase the surface area to develop more active sites that capture anionic dyes from aqueous solution. Fixed-bed adsorption studies were conducted to investigate the performance of using quartenized kenaf core fiber (QKCF) as an adsorbent for the removal of anionic acid dyes from a binary system. The effects of operational parameters, including inlet dye concentration, flow rate, and bed height, were studied in a fixed-bed column system, while other process parameters were fixed, i.e. pH and temperature at 7.5 and 27 ºC, respectively. The fixed-bed column performed better with lower influent dye concentration, less flow rate of the influent, and a higher adsorbent bed depth. Overall, the present study showed that QKCF is a potential adsorbent for anionic dye removal from aqueous solutions in a fixed-bed column system.
