“…Their cellulase activity of CF may release organic fertilizer-associated nutrients, including N. As a result of nitrogen mineralization during the decomposition of organic fertilizers, the carbon content of the organic fertilizers decreases while the total nitrogen content rises. Similar reasons are also reported [36,37] Another possibility was that those microorganisms varied the number of organic chemicals they released, such as amino acids and sugars, to enhance the N content of organic fertilizers [17,38,39]. Those chemicals were components of bacterial and fungal cell walls [40,41].…”

Cellulolytic fungi are involved in releasing nutrients from organic sources. The objective of this study was to determine the effect of cellulolytic fungi on the total nitrogen (N), total phosphorus (P), and total potassium (K) contents in different organic fertilizers. This study was arranged in randomized block design 3 X 3 with three replications. There were two factors, cellulolytic fungi (Talaromyces pinophilus strain MR107, Penicillium sp. isolate SR18, and Purpureocillium lilacinum isolate PIGD23i) and organic fertilizers (cow manure, compost, and vermicompost). The results indicated that Penicillium sp. isolate SR18 had a better effect than other cellulolytic fungi species on tot. N, tot. P and tot. K contents of cow manure; tot. N and tot. K contents of compost; and tot. P content of vermicompost while P. lilacinum isolate PIGD23i showed a better effect on tot. N and tot. K contents of vermicompost. The highest tot. N, and tot. K contents were found in P. lilacinum isolate PIGD23i-inoculated vermicompost while the tot. P content was in Penicillium sp. isolate SR18-inoculated vermicompost. Overall, adding cellulolytic fungi is an alternative way to improve the nutrient content of organic fertilizer.

“…e performance of P solubilization with the aid of using JEC4 strain was considered and located to be within the range of 92 μg/ml-284.4 μg/ml (from Figures 1(a)-1(c)), that is similar to the PSB isolated from the rhizosphere of Allium hookeri thwaites (124.8-266.4 μg/ mL) [38] and better than PSB of Bacillus sp.

“…Additionally, the authors of [40] observed maximum soluble phosphate at 7 days of growth. e reason for the increased solubility of phosphate is due to the production of acids with the increase in the period of incubation [41]. But, the additional increase in incubation time has led to a decrease in phosphate solubilization activity; subsequently, the efficiency of the microorganism population to affect phosphate solubilization from tricalcium phosphate would be discounted if this variable were to be excessively high.…”

Plant growth-promoting rhizobacteria (PGPR) are an important bacterial resource as biofertilizers, which can promote plant growth and increase crop yields. In this study, isolation, characterization, and its effect on plant promotion were assessed by isolating PGPR using soil samples collected from Jimma, Ethiopia. Out of 10 isolates, three of them (JEC3, JEC4, and JEC7) exhibited PSB traits in Pikovskaya media by solubilizing phosphate and producing IAA. Of the three isolates, JEC4 recorded the maximum phosphate solubilization index (4.98), soluble phosphate (283 μg/ml), and IAA production (10.21 μg/ml). The findings of the isolates' morphological and biochemical tests showed that JEC3, JEC4, and JEC7 as Bacillus sp., Pseudomonas sp., and Enterobacter sp., respectively. The optimization of phosphate solubilization was done using different incubation times and sources of carbon and nitrogen. Furthermore, the isolate (JEC4) was tested for plant growth-promoting (PGP) activities and indicated the production of ammonia, hydrogen cyanide, and siderophore. JEC4 isolate showed a significant increase in sideways (%) seed germination, root and shoot length, fresh and dry weight of root, and shoot of maize in field experiments than the untreated ones. The results indicate that the JEC4 isolate can be developed as a biological fertilizer for promoting crop productivity and ecosystem dynamics.

“…Previous studies have shown that the addition of exogenous composite bacterial systems can change the indigenous microbial community structure to some extent, which means that increasing significantly the abundance and diversity of predominant bacteria and maintaining long-term stability ( Chen et al, 2021 ; Nigussie et al, 2021 ). Recent studies have shown that exogenous composite microbial systems can be directly applied to incorporated straw.…”

Low temperature is one of the bottleneck factors that limits the degradation of straw during rice straw incorporation. Determining strategies to promote the efficient degradation of straw in cold regions has become a highly active research area. This study was to investigate the effect of rice straw incorporation by adding exogenous lignocellulose decomposition microbial consortiums at different soil depths in cold regions. The results showed that the lignocellulose was degraded the most efficiently during straw incorporation, which was in deep soil with the full addition of a high-temperature bacterial system. The composite bacterial systems changed the indigenous soil microbial community structure and diminished the effect of straw incorporation on soil pH, it also significantly increased rice yield and effectively enhanced the functional abundance of soil microorganisms. The predominant bacteria SJA-15, Gemmatimonadaceae, and Bradyrhizobium promoted straw degradation. The concentration of bacterial system and the depth of soil had significantly positive correlations on lignocellulose degradation. These results provide new insights and a theoretical basis for the changes in the soil microbial community and the application of lignocellulose-degrading composite microbial systems with straw incorporation in cold regions.
