“…This friable consistency may be less or absent in coarse textured EFBC compost material, making the attachment of bacterial cells to the surface of the support material less efficient. BRHs play the role of a nutrient-rich carrier material containing carbon, reducing sugars, nitrogen, and vitamins to stimulate microbial growth (Wang, 2012;Chen et al 2016). The EFBC also play an important role in providing nutrients to the microorganisms.…”

The current interest in minimizing the use of inorganic fertilizers and the increasing demand for the combined action of beneficial microorganisms and agricultural wastes is considered to have a positive impact on soil, crop productivity and sustainable agriculture. The objective of this study was to prepare a series of combinations of empty fruit compost (EFBC) and burnt rice husk (BRH) as carrier materials for selected nitrogen-fixing bacteria, evaluate their suitability, and determine the ability of the inoculated EFBC-BRH carrier materials. Different ratios of EFBC and BRH were used to prepare the carrier materials for the selected N₂-fixing bacteria, namely strains Sb35 and Sb42 of Bacillus sp. Both coarse and fine EFBCs were used for the preparations. The suitability of the combinations of EFBC-BRH as a bacterial carrier was tested by inoculating the different ratios of organic material combinations with the N₂-fixing bacteria and incubating them at room temperature for eight weeks, after which the effects on the bacterial population, pH, moisture content, and contaminants were determined. The results showed that the fine-textured EFBC-BRH carriers’ formulation (T5 to T8) were better carriers compared to the formulation of coarse-textured EFBC-BRH carriers (T1 to T4). The inoculated carrier T6 (1 fine structured EFBC: 1 BRH) showed the best response with an increase in Sb35 and Sb42 populations of 7.34% and 7.47%, respectively. In conclusion, T6 as a carrier material for Sb35 and Sb42 is suitable to be developed as a biofertilizer.

“…A novel study used an exogenous Bacillus subtilis to strengthen the IMEOR process [13]. IMEOR relies of the combination of various mechanisms, such as oil emulsification, oil bio-degradation, gas production, acid production and viscosity reduction [11,14,15]. In a large-scale IMEOR pilot field, 210,000 tonnes of crude oil were produced cumulatively by injection of nutrients with water [16].…”

This study stimulated functional microbial adaptation to the extreme environment of the Luliang oilfield reservoir and assessed the impact of indigenous microbial enhanced oil recovery treatment on the microbial community and oil recovery. By high-resolution pyro-sequencing, Acinetobacter, Pseudomonas, Sphingomonas, Thauera, Arcobacter and Hyphomonas were regarded as suitable candidates and a customised nutrient mixture was selected to activate the target microbes. The interfacial tension of crude oil and water decreased from 29.76 mN m À1 to 0.65 mN m À1 and the emulsion stability index increased from 5% to 92% after customised nutrient culture. The oil biodegradation experiments after the cultivation exhibited positive effects in degrading aromatics, resins and asphaltenes fractions and improving the mobility. Six target genera were activated markedly after 96 h of incubation. The oil recovery was enhanced from 51.2% to 60.7% using fermentation broth injection. Thus, injecting a customised nutrient mixture with injection brine into the stratum to stimulate functional microbes has the potential to enhance oil recovery in the Luliang oilfield.
