“…The intake of molecular oxygen or the generation of CO 2 can be used to measure microbial activity and aerobic metabolism using respirometry [145]. Furthermore, respirometric studies can be used to examine the possible decomposition in soil of petroleum hydrocarbons, nutritional limits, the heavy metal ability to, toxic chemicals, clayey acidic soil, and the impact of pH on soil microbial activity [146][147][148][149].…”

“…Slurry bioreactors of various sizes can also be used to test biodegradation capability. These bioreactors have numerous benefits, such as effective aeration, mixing and better substrate supply, as well as can drastically shorten treatment time [145,149]. Fourier-transform infrared spectroscopy (FTIR), high-performance liquid chromatography (HPLC), mass spectrometry (MS), gas chromatography, infrared (IR) absorption, and thin-layer chromatography (TLC) among other techniques are used to evaluate the rates of contaminant degradation and product creation [148].…”

The rise in environmental pollution over the past few decades due to rapid industrialization and unsafe agricultural practices has become a major challenge. The presence of toxic pollutants such as nuclear wastes, heavy metals, pesticides, and hydrocarbons has been languishing the environment as well as the human health. Bioremediation using microbial communities is emerging as an incredible, eco-friendly, and cost-effective approach to ameliorate the adverse effects of toxic pollutants. Microbes possess astonishing metabolic capabilities to alter most forms of organic material and can survive in extreme environmental conditions which make them attractive candidate for the bioremediation. Microbes are the treasure houses for environmental cleaning and recovering of contaminated soil and they have been reported from diverse environmental conditions including hot, cold, drought, and saline. Different groups of bioremediating microbes have reported from diverse conditions, that is, bacteria, fungi including yeast, and algae. Microbes belonging to genera Alcaligenes, Aspergillus, Bacillus, Flavobacterium, Ganoderma, Methosinus, Nocardia, Phormidium, Pseudomonas, Rhizopus, Rhodococcus, and Stereum have been reported as potential and efficient bioremediators for the degradation of different pollutants of the environment such as xenobiotics, heavy metals, hydrocarbons, and paper and pulp effluent. The present review focuses on microbial diversity in bioremediation, techniques applied in bioremediation, bioremediation of different environmental pollutants, and how bioremediation processes could be monitored.

Casuarina equisetifolia (Casuarinaceae) growth in soil with diesel and application of biostimulation and bioaugmentation. Phytoremediation is an ecologically sound biotechnology directed to cleaning up contaminated soils. The study of tree species to treat petroleum contaminated soils is scarce; moreover, the combination of phytoremediation with bioaugmentation and biostimulation processes is also limited. Thus, this work evaluated the effects of the inoculation of Glomus intraradices, a bacterial consortium (M2BOS1-R2 and M2BOSI-F4) and Trichoderma viride, on the growth of Casuarina equisetifolia, fertilized with Floranid ® or Triple 17, when sown in a diesel-contaminated soil (7 500mg/kg). The factorial experiment 2x5x3 included 30 treatments with 10 replicates in a completely randomized design under greenhouse conditions for 120 days. Diesel significantly diminished plant height, total biomass, and plant index quality (PIQ). Glomus or bacterial consortium significantly increased plant height, total biomass and PIQ when compared to the inoculation of the three microorganisms or to the control. Floranid had negative effects on plant growth and PIQ at diesel contamination. Fertilization with Triple 17 combined with the three microorganisms stimulated plant growth in the absence of diesel, whereas in the presence of this contaminant the treatments combining Triple 17 with the bacterial consortium or with Trichoderma had better plant growth and PIQ. Mycorrhizal colonization was inhibited due to diesel contamination, and especially when Floranid was applied. The fertilizer Triple 17 (biostimulation) combined with the beneficial microorganisms (bioaugmentation) improved growth responses of C. equisetifolia in diesel-contaminated soil.
