“…Factors like pH, temperature, structure of dye, soluble salts, heavy metals, nutrients, etc., affect the degradation of dye (Al-Amrani et al, 2014). There are various reports available which shows degradation of different dyes using microorganisms (Mane et al, 2008;Varjani and Upasani, 2016;Kiayi et al, 2019;Li et al, 2019;Pratiwi et al, 2019).…”

Industrialization increases use of dyes due to its high demand in paper, cosmetic, textile, leather and food industries. This in turn would increase wastewater generation from dye industrial activities. Various dyes and its structural compounds present in dye industrial wastewater have harmful effects on plants, animals and humans. Synthetic dyes are more resistant than natural dyes to physical and chemical methods for remediation which makes them more difficult to get decolorize. Microbial degradation has been researched and reviewed largely for quicker dye degradation. Genetically engineered microorganisms (GEMs) play important role in achieving complete dye degradation. This paper provides scientific and technical information about dyes & dye intermediates and biodegradation of azo dye. It also compiles information about factors affecting dye(s) biodegradation, role of genetically modified organisms (GMOs) in process of dye(s) degradation and perspectives in this field of research.

A large number of industries use heavy metal cations to fix dyes in fabrication processes. Malachite green (MG) is used in many factories and in aquaculture production to treat parasites, and it has genotoxic and carcinogenic effects. Chromium is used to fix the dyes and it is a global toxic heavy metal. Face centered central composite design (FCCCD) has been used to determine the most significant factors for enhanced simultaneous removal of MG and chromium ions from aqueous solutions using marine green alga Enteromorpha intestinalis biomass collected from Jeddah beach. The dry biomass of E. intestinalis samples were also examined using SEM and FTIR before and after MG and chromium biosoptions. The predicted results indicated that 4.3 g/L E. intestinalis biomass was simultaneously removed 99.63% of MG and 93.38% of chromium from aqueous solution using a MG concentration of 7.97 mg/L, the chromium concentration of 192.45 mg/L, pH 9.92, the contact time was 38.5 min with an agitation of 200 rpm. FTIR and SEM proved the change in characteristics of algal biomass after treatments. The dry biomass of E. intestinalis has the capacity to remove MG and chromium from aquatic effluents in a feasible and efficient manner.

“…Akhtar et al 4 found that adsorption of nickel onto the biomass of Chlorella sorokiniana immobilized in loofa sponge was rapid and reached equilibrium after only 15 min. On the contrary, the biosorption capacity increased with increasing contact time up to 110 min, after which the equilibrium was attained and the biosorption capacity is less constant 53 . Pahlavanzadeh et al 39 stated that the biosorption capacity of nickel by dried algal biomass increased with increased time of contact and the equilibrium was attained within 120 min.…”

“…that can serve as metal binding sites 52 . The maximum adsorption percentage of methylene blue removal value was 92% from solutions using marine algae Ulva lactuca was found at around pH 8 53 . A fewer anionic adsorption sites were generated on the surface of the biosorbent (the dried algal biomass) at low pH values, and the sorption process decreased probably due to electrostatic repulsion between excess H + in the solution and the cationic dye molecules for sorption sites on the dried algal biomass 51 .…”

The pollution of water by heavy metal ions and dyes, particularly from industrial effluents, has become a global environmental issue. Therefore, the treatment of wastewater generated from different industrial wastes is essential to restore environmental quality. The efficiency of Gracilaria seaweed biomass as a sustainable biosorbent for simultaneous bioremoval of Ni2+ and methylene blue from aqueous solution was studied. Optimization of the biosorption process parameters was performed using face-centered central composite design (FCCCD). The highest bioremoval percentages of Ni2+ and methylene blue were 97.53% and 94.86%; respectively, obtained under optimum experimental conditions: 6 g/L Gracilaria biomass, initial pH 8, 20 mg/L of methylene blue, 150 mg/L of Ni2+ and 180 min of contact time. Fourier Transform Infrared Spectroscopy (FTIR) spectra demonstrated the presence of methyl, alkynes, amide, phenolic, carbonyl, nitrile and phosphate groups which are important binding sites involved in Ni2+ and methylene blue biosorption process. SEM analysis reveals the appearance of shiny large particles and layers on the biosorbent surface after biosorption that are absent before the biosorption process. In conclusion, it is demonstrated that the Gracilaria seaweed biomass is a promising, biodegradable, ecofriendly, cost-effective and efficient biosorbent for simultaneous bioremoval of Ni2+ and methylene blue from wastewater effluents.
