“…Several PGPB genera show association with different species of agricultural importance, such as Azospirillum, Bacillus and Pseudomonas (Zeffa et al, 2018). These bacteria can stimulate plant growth by a series of mechanisms, including but not restricted, the production of phytohormones, such as salicylic acid, gibberellins, cytokinins and indole-3-acetic acid (IAA) (Cassán and Diaz-Zorita, 2016;Fukami et al, 2017), phosphate solubilization (Ludueña et al, 2018;Qi et al, 2018), nutrient availability increase (Galindo et al, 2018b), production of indolic compounds and siderophores (Ambrosini and Passaglia, 2017), increase on 1−aminocyclopropane−1−carboxylate deaminase activity (Ambrosini and Passaglia, 2017), biological nitrogen fixation (BNF) (Pankievicz et al, 2015), biological control of plants, production of natural antibiotics and protective effect against secondary soil phytopathogens (Zhou et al, 2016;Mishra and Arora, 2018;Shameer and Prasad, 2018).…”

The use of plant growth promoting bacteria (PGPB) that can solubilize phosphorus (P) has shown potential to improve nutrient availability in grass crops such as corn (Zea mays L.) This study was developed to investigate if inoculation with Azospirillum brasilense, Bacillus subtilis or Pseudomonas fluorescens associated with P 2 O 5 rates can improve phosphorus use efficiency (PUE) reflecting on greater corn development and yield. The field trial was set up in a Rhodic Hapludox under no-till system under Savannah conditions, in a completely randomized block design with four replicates. Treatments were tested in a full factorial design and included: (i) five P 2 O 5 rates (0 to 105 kg ha −1) and (ii) four PGPB seed inoculation (Control-without inoculation, A. brasilense, B. subtilis or P. fluorescens). Inoculation was found to increase grain yield by 39.5, 29.1, and 15.9% when B. subtilis was inoculated in the absence of P 2 O 5 rates and associated with 17.5 and 70 kg P 2 O 5 ha −1 and by 34.7% when A. brasilense was inoculated with application of 105 kg P 2 O 5 ha −1. In addition, inoculation with B. subtilis and A. brasilense were found to increase P uptake, benefiting productive components development, leading to an improved PUE, and greater corn grain yield. The results of this study showed positive improvements in P uptake as a result of B. subtilis and A. brasilense inoculation, with an increase of 100.5 and 54.6% on PUE, respectively; while the P. fluorescens inoculation were less evident. Further research should be conducted under biotic or/and abiotic conditions such as attack of pathogens and insects, drought, salinity, water flooding, low and high temperature to better understand the role of PGPB, inoculated alone or in combination as the co-inoculated method.

“…Hence codigestion improved and enriched the biofertilizer properties of the resultant digestion product. This increase in populations of PGPB could be attributed to the use of goat manure as co-substrate and studies have shown that anaerobic digestate can serve as sources of biofertilizing bacteria through the addition of readily available nutrients to soil [21,34,41].…”

“…For example, the available nitrogen in the digester is converted to ammonium and nitrates which remain in the digester until the end of the anaerobic digestion process [19]. Besides being imbued with nutrients such as nitrogen, phosphorus and potassium, the digestate from biogas plants/digesters has been shown to be rich in populations plant growth promoting bacteria (including Bacillus and Pseudomonas species) with remarkable biofertilizer attributes hence its potential for use as biofertilizer [20,21]. Notwithstanding, the digestate is not entirely innocuous (as it may harbour some pathogens) thus requiring continuous monitoring and evaluation of its quality before use on arable land [22][23][24][25][26].…”

Comparative assays were conducted to assess the biogas and biofertilizer production efficiency from anaerobically codigested goat manure (GM) and harvest residues: corn stover (CS) and rice straw (RS). All digesters were operated simultaneously under mesophilic temperature of 40°C and notable phosphate solubilizing and nitrogen fixing bacterial populations indicated qualitative biofertilizer quality of the digestates. Codigestion of the substrates significantly increased biogas yield (p < 0.05) compared to monodigestion, and the highest cumulative yield of 573 ml/g VS was obtained from codigested rice straw (RS) and goat manure (GM). With a significant decimation in number of pathogens (p < 0.05), a 2 – 3 fold increase in populations of plant growth promoting bacteria (Bacillus and Pseudomonas species) was observed in digestate from codigestion assays when compared to monodigestion (control) and were identified as Clostridium sp., Bacillus subtilis, Bacillus megaterium, Lactobacillus sp., Pseudomonas fluorescens including methanogens: Methanothrix sp., Methanobacterium sp. and Methanosarcina sp. On the average, codigestion assays resulted in enhanced biogas yield and biofertilizer quality that was 2.3 – 4.1 times higher than single substrate digestion and generally improved the efficiency of biogas and biofertilizer production.

“…Effluent commonly contains many microorganisms which are the function components for bio-fertilizers manufacture. For example, Clostridium and Klebsiella can be responsible for nitrogen fixation, while Bacillus and Pseudomonas can be used for phosphate solubilization [146][147][148][149][150]. Overall, when compared to chemical fertilizers, degraded organic matter and these microorganisms can accelerate the microbial processes in the soil and promote the availability of fertilization nutrients to plants.…”

Municipal solid waste (MSW) management has emerged as probably the most pressing issue many governments nowadays are facing. Traditionally, Waste-to-Energy(WtE) is mostly associated with incineration, but now, with the emergence of the bioeconomy, it embraces a broader definition comprising any processing technique that can generate electricity/heat or produce a waste-derived fuel. Under the ambit of the circular economy many nations are looking for, additional effort must be made to be sure of acquiring the most updated information and paving a sustainable path for managing MSW in such a frame. In this regard, we have undertaken a critical review of various technologies, with their updated progress, involved in the exploitation of MSW as a renewable resource, along with the critical advantages and limitations on energy and material cycling for sustainable MSW management. Incineration, the most widely used method, is nowadays difficult to further apply due to its dubious reputation and social opposition. Meanwhile, to address the organic fraction of MSW which currently is mostly unrecycled and causes disposal issues, the biological approach presents an attractive option. The new emphasis of bioeconomy leads us to understand how environmental biotechnologies should be better connected/integrated for more sustainable MSW management. This article is concluded with advances of future prospects, which can serve as a timely reminder to encourage competent authorities/researchers to work towards further improvement of the present MSW management system.
