“…A recent research study was conducted to evaluate the effect of microalgae biofilm as phytoremediation agent of petroleum contaminated water. Percentage removal efficiency of physicochemical parameters was found as turbidity 81%, alkalinity 28.4%, BOD 16.7%, COD 8%, electrical conductivity 51.2%, TDS 7.9%, TSS 26%, and salinity 23.4% (Ugya et al, 2021). This study showed lower percentage efficiency of parameters compared to the current study.…”

BackgroundTannery wastewater effluents contain many toxic and carcinogenic heavy metals and physiochemical parameters that need to be removed before these effluents enter in the main water bodies or rivers. In this study, the effluents from the tannery industry are treated through aeration, coagulation, and Chlorella vulgaris pond treatment processes for the removal of physiochemical: parameters only.MethodsThe effect of removal efficiencies (%) was studied on the physicochemical parameters, including salinity, electrical conductivity (EC), total dissolved solids (TDS), turbidity, total suspended solids (TSS), biochemical oxygen demand (BOD), and chemical oxygen demand (COD).ResultsThe key results showed that the removal of EC, TDS, turbidity, TSS, BOD, and COD was 80.2%, 67%, 81%, 80.8%, 68.6%, and 100%, respectively, in raw wastewater treatment having 25, 50, and 70 g of algae C. vulgaris doses. The removal efficiencies (%) of salinity, EC, TDS, turbidity, TSS, BOD, and COD were 83%, 87.1%, 77.1%, 80%, 40%, 97%, and 98%, respectively, during coagulated wastewater treatment with three doses of algae. The observed improvement in treated wastewater indicated that the removal efficiencies (%) of salinity, EC, TDS, turbidity, TSS, BOD, and COD were 85.7%, 39.3%, 81.3%, 67.8%, 50.3%, 97%, and 98%, with C. vulgaris.ConclusionThis study confirmed that the treatment of tannery wastewater by these processes increased the pollutant removal efficiencies as all the physiochemical parameters were exceeding the permissible limits.Results contribution in futureThis research will be helpful to treat the industrial wastewaters or effluents before it further mixes up in the main water streams. In this way, water quality will be better, aquatic life will be saved, and further researchers can analyze more ways for efficient treatments as they have a baseline data through this study findings.Practitioner Points One of the most pollutant sources in terms of both physical and chemical parameters is the produced wastewater from tannery industries. The effluents from tannery industry are treated through aeration, coagulation, and algae ponds treatment processes. These treatment made the tannery wastewater as environmental friendly.

Petroleum hydrocarbons are one of the most prevalent and ubiquitous environmental pollutants, causing health and environmental risks, so some isolates from cows and buffalos were used in this study to remove these pollutants. Nine isolates of Lactobacillus spp from 20 samples of cows and buffalos milk types. 5 Lactobacillus acidophilus isolates were used in this study because of their excellent production of bacteriocin compared with the other species. The isolates were purified as follows: 70% saturation of ammonium salt followed by gel filtration on Sephadex -G150 was used to purify the bacteriocin. It resulted in a 47.75 % yield with 4.7-fold purification. The results of this study showed the use of 80µg/ml of bacteriocin increased the removal of hydrophobic pollutants from the burned motor and engine oils by 41% after 24 hours, which was more efficient than high doses of bacteriocin. For example, 100 µg/mL of bacteriocin removed only 33% of the contaminants. Furthermore, by extending the incubation period to 7 days, the hydrocarbon degradation percentage was increased by 78% in engine oil and 89% in burned motor oil. Thus, it can be concluded that bacteriocin bioremediation is an efficient and cost-effective biological treatment for eliminating petroleum hydrocarbons from water and protecting natural resources.

“…Microalgae are an important biotechnological tool which has diverse industrial application including biofuels, food, feed, cosmetics, aquaculture, and pharmaceuticals (Raja et al, 2018). The studies on the use of microalgae biomass as a source of renewable energy is intensifying, because under suitable culture conditions, most microalgae species tend to accumulate up to 50-70% of lipid per dry weight which are suitable for the synthesis of biofuels (Amaro et al, 2017;Ugya et al, 2021c).…”

The autotrophic forms of microalgae are referred to as "efficient biological factories", because they play a significant role in CO 2 removal from the atmosphere by utilizing it for the process of photosynthesis. The industrial application of microalgae biomass includes the production of cosmetics, health products, fertilisers, biofuel, feeds, and food. Microalgae biomass is also an important tool used in the treatment of wastewater. The current review is aimed at reviewing the progress and prospects of microalgae resource modelling and optimisation as a tool for sustainable biotechnology. The mechanism of biomass production by microalgae tends to vary according to whether the microalgae are autotrophic, heterotrophic, or mixotrophic organisms. In the current study, the modelling and optimisation of microalgae biomass production were discussed, as well as the modelling of CO 2 sequestration, light intensity, nutrients, and photobioreactor. The role of microalgal biomass production in attaining sustainable biotechnology has also been extensively studied. Microalgae are an emerging tool used in the phycoremediation of wastewater and reduction of high CO 2 level. The modelling and optimisation of microalgae biomass production will help to upscale the production of the microalgal based fuel and bioproducts from model scale to the money-making level.
