House dust contains different biocomponents. Algae are one of the important biocomponents of house dust and is present in the form of spores and filaments. Dust samples were collected from houses of patients suffering from respiratory allergy in Aurangabad city during September 2017 to August 2018. Total of 34 samples were collected and cultured in the petriplates containing agarized Bold’s basal medium (BBM). Algal forms belonged to Chlorophyceae, Bacillariophyceae and Cyanophyceae were cultured and identified. Cyanophycean algae dominated the algal flora of house dust. Algal taxa which were found abundant in house dust are Chlorococcum humicola, Chlorella vulgaris, Nitzshia palea, Aphanothece nidulans, Phormidium molle, Microcoleus acutissimus, and Plectonema gracillimum.  16 algal taxa recorded in the present study are allergenic to human beings.

The Impact

In the last years, nanoparticles such as TiO2, ZnO, NiO, CuO and Fe2O3 were mainly used in wastewater applications. In addition to the positive aspects concerning using nanoparticles in the advanced oxidation process of wastewater containing pollutants, the impact of these nanoparticles on the environment must also be investigated. The toxicity of nanoparticles is generally investigated by the nanomaterials’ effect on green algae, especially on Chlorella vulgaris. In this review, several aspects are reviewed: the Chlorella vulgaris culture monitoring and growth parameters, the effect of different nanoparticles on Chlorella vulgaris, the toxicity of photocatalyst nanoparticles, and the mechanism of photocatalyst during oxidative stress on the photosynthetic mechanism of Chlorella vulgaris. The Bold basal medium (BBM) is generally recognized as an excellent standard cultivation medium for Chlorella vulgaris in the known environmental conditions such as temperature in the range 20–30 °C and light intensity of around 150 μE·m2·s−1 under a 16/8 h light/dark cycle. The nanoparticles synthesis methods influence the particle size, morphology, density, surface area to generate growth inhibition and further algal deaths at the nanoparticle-dependent concentration. Moreover, the results revealed that nanoparticles caused a more potent inhibitory effect on microalgal growth and severely disrupted algal cells’ membranes.

Aim: The work was aimed at assessing the potential of Chlorella vulgaris in remediation of reactive dyes. Place and Duration of Study: Department of Biological Sciences, Department of Plant Biology and Department of Biochemistry, Bayero University, Kano, Nigeria, between January 2019 and December 2019. Methodology: Wastewater containing individual reactive dyes: reactive red 198 (RR198), reactive yellow 176 (RY176), reactive green 19 (RG19), reactive orange 122 (RO122), reactive red 195 (RR195) and reactive violet 1 (RV1) were collected from a local fabric re-dyeing pit at Kofar Na’isa, Kano, Nigeria. The green microalga C. vulgaris was cultured in Bold Basal medium (BBM) at 30 ± 2°C and subjected to adsorption and decolourization assays of the dyes. Results: The highest dye removal efficiency by enzymatic action was recorded after 48 hours, while that for the biomass adsorption was at day 14, at pH 11.3 and temperature of 30°C. The percentage dye removal by adsorption and decolourization were within the ranges of 68.1-97.8% and 69.8-99.9% respectively. Dye removal decreased with increase in contact time until saturation is attained. Freundlich’s isotherm model was best fitted for the adsorption of the dyes with a strong linear correlation coefficient, R2 ranging from 0.954-0.811. There was a strong linear relationship and high statistical significance among the dyes for both decolourization and adsorption (P value; .01). Conclusion: Chlorella vulgaris was found to be effective in the removal of reactive dyes from textile wastewater samples. The results revealed C. vulgaris to be a cost-effective and eco-friendly biosorbent that can be used for the treatment of wastewaters containing toxic dyes.

Nutrient Removal Efficiency

Domestic wastewater contains chemical compounds that can be used as nutrients for microalgae. Removing these chemical compounds from wastewater by microalgae might help in reducing the operation cost of wastewater management while minimizing the cultivation cost for large-scale microalgae metabolite production. In this study, domestic wastewater collected from Indah Water Konsortium (IWK), Kuala Lumpur, Malaysia, was assessed as growth media for two types of microalgae, namely Chlorella vulgaris and Haematococcus pluvialis. The biomass growth and nutrient removal efficiency of total nitrogen (TN), total phosphorus (TP), and total ammonia (TAN) in different concentrations of diluted wastewater were measured. The results showed that biomass concentration (0.227 g/L), biomass productivity (0.029 g/L/day), and specific growth rate (0,284 d-1) yielded by C. vulgaris in 14 days of 80% wastewater were comparable to those microalgae grew in standard Bold’s Basal medium (BBM). Besides, C. vulgaris grew in 50% wastewater to remove TN, TP, and TAN with the highest removal efficiency (>88%). For H. pluvialis, the biomass concentration in all wastewater concentrations was lower than BBM. The removal efficiencies of TN and TP were lower than 55%, but more than 80% for removal efficiency of TAN in 50% and 80% wastewater. Hence, C. vulgaris has better growth performance and nutrient removal efficiency than H. pluvialis. These findings indicated that IWK domestic wastewater could be used as growth media for microalgae, especially C. vulgaris.
