“…Therefore Aspergillus spp. can shorten the maturation period of the substrate by releasing certain enzymes such as cellulase, amylase, xylanase, and pectinase for the decomposition of lignocellulosic waste (Naeem et al 2021). Furthermore, genera Coprinellus, Clonostachys, Arizonaphlyctis, Bolbitius, and Rhizophlyctis were dominant with leguminous green manure.…”

Green manure can sustain agricultural production, preserve biodiversity, and mitigate soil degradation caused by long-term application of chemical fertilizers. Moreover, the application of green manure can improve soil health through increased soil biological activities. Nevertheless, little attention has been paid to the effects of leguminous and non-leguminous plants on phosphorus-and carbon-related enzyme activities and fungal community composition in soil. In this study, a pot experiment was carried out to elucidate the effects of two green manures on plant growth promoting potential, phosphorus-and carbonrelated enzyme activities, and soil fungal community composition. Two green manure treatments (Brassica juncea and hairy vetch), poultry compost and control (no amendment) were applied and soil samples were collected after incorporation of green manure and after plant harvest. The results revealed that plant growth with hairy vetch was significantly higher than that with B. juncea and poultry compost, and soil enzyme activities were markedly higher with hairy vetch than with B. juncea. Both green manure amendments altered the soil fungal community composition. It is possible that the incorporation of green manure into soil and their mineralization and decomposition were controlled by the carbon: nitrogen ratio of the manures and that these manures were easily degradable by soil fungi. In particular, the incorporation of leguminous (hairy vetch) green manure with a low carbon: nitrogen ratio resulted in better plant growth through fast mineralization. Our findings suggest that green manure incorporation is an effective practice and provides substantial benefits to the soil-plant system.

“…There are few reports about IPF activity as solubilizers of nutrients. Some studies showed similar data using the well-known genus Trichoderma [ 71 ] and others using the saprophyte Aspergillus niger showing abilities as phosphorus solubilizers [ 72 , 73 , 74 , 75 ]. Recent studies by Barra-Bucarei et al [ 11 ] showed differences between five isolates of B. bassiana .…”

Endophytic insect pathogenic fungi have a multifunctional lifestyle; in addition to its well-known function as biocontrol agents, it may also help plants respond to other biotic and abiotic stresses, such as iron (Fe) deficiency. This study explores M. brunneum EAMa 01/58-Su strain attributes for Fe acquisition. Firstly, direct attributes include siderophore exudation (in vitro assay) and Fe content in shoots and in the substrate (in vivo assay) were evaluated for three strains of Beauveria bassiana and Metarhizium bruneum. The M. brunneum EAMa 01/58-Su strain showed a great ability to exudate iron siderophores (58.4% surface siderophores exudation) and provided higher Fe content in both dry matter and substrate compared to the control and was therefore selected for further research to unravel the possible induction of Fe deficiency responses, Ferric Reductase Activity (FRA), and relative expression of Fe acquisition genes by qRT-PCR in melon and cucumber plants.. In addition, root priming by M. brunneum EAMa 01/58-Su strain elicited Fe deficiency responses at transcriptional level. Our results show an early up-regulation (24, 48 or 72 h post inoculation) of the Fe acquisition genes FRO1, FRO2, IRT1, HA1, and FIT as well as the FRA. These results highlight the mechanisms involved in the Fe acquisition as mediated by IPF M. brunneum EAMa 01/58-Su strain.

“…The current study determines the potassium mobilizing activity of P. aeruginosa CD6C by the creation of the transparent zone on Aleksandrov culture media containing an insoluble form of K as feldspar (Naeem et al 2022). However, very low potassium solubilizing activity was recorded after eight days of incubation (27.1 ± 1.1 µg/ml) with a signi cant drop in pH and reduced the pH to 6.1 from the initial pH of 7.0 of the medium.…”

The current study aimed to explore non-pathogenic, non-aflatoxigenic and competent microbial isolates accountable for producing hydrolytic enzymes and plant growth-stimulating hormones for proficient and augmented conversion of agricultural waste press mud (PM) into biofertilizer through composting. Four bacterial (B. altitudinis CD2E, P. aeruginosa CD6C, B. velezensis BS2, B. wiedmannii BTA) and one fungal isolate (A. niger PM-4) were selected for microbial inoculum formulation for composting of PM heaps in different treatments. The compatibility studies found that the bacterial isolates were compatible with each other, however, A. niger PM-4 was found non-compatible with P. aeruginosa CD6C and B. velezensis BS2. The heap containing bacterial consortium T3 (PM + consortium) found its maturity on the 21st day by reducing more C/N, total organic carbon (TOC), higher total Kjeldahl nitrogen (TKN) 2.15+0.02%, total phosphorous (TP) (1.42+0.01%), and total potassium (TK) (1.0+0.03%) than any other treatments.
