Abstract
We studied the influence of microorganisms isolated from permafrost on the psychophysiological parameters of birds. Significant effect of the microbiota of the paleoecosystems of the cryolithozone on locomotor activity, psycho-emotional state, and psychophysiological lateralization of brain function of Gallus gallus chickens. The involvement of both the autonomic and the higher central nervous systems in this regulatory process via synthesis of neuropeptides by symbionts is discussed.

Isolation and characterization of plant growth-promoting endophytic bacteria Bacillus stratosphericus LW-03 from Lilium wardii. 3 Biotech 2020; 10:305. [PMID: 32612899 PMCID: PMC7313711 DOI: 10.1007/s13205-020-02294-2] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2019] [Accepted: 06/07/2020] [Indexed: 02/01/2023] Open
Abstract
In the present study, a new strain of Bacillus stratosphericus LW-03 was isolated from the bulbs of Lilium wardii. The isolated endophytic strain LW-03 exhibited excellent antifungal activity against common plant pathogens, such as Fusarium oxysporum, Botryosphaeria dothidea, Botrytis cinerea, and Fusarium fujikuroi. The growth inhibition percentage of Botryosphaeria dothidea was 74.56 ± 2.35%, which was the highest, followed by Botrytis cinerea, Fusarium fujikuroi, and Fusarium oxysporum were 71.91 ± 2.87%, 69.54 ± 2.73%, and 65.13 ± 1.91%, respectively. The ethyl acetate fraction revealed a number of bioactive compounds and several of which were putatively identified as antimicrobial agents, such as 4-hydroxy-2-nonenylquinoline N-oxide, sphingosine ceramides like cer(d18:0/16:0(2OH)), cer(d18:0/16:0), and cer(d18:1/0:0), di-peptides, tri-peptide, cyclopeptides [cyclo(D-Trp-L-Pro)], [cyclo (Pro-Phe)], dehydroabietylamine, oxazepam, 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphocholine like compound (PC(0:0/20:4), phosphatidylethanolamine (PE(18:1/0:0)), 3-Hydroxyoctadecanoic acid, 7.alpha.,27-Dihydroxycholesterol, N-Acetyl-d-mannosamine, p-Hydroxyphenyllactic acid, Phytomonic acid, and 2-undecenyl-quinoloin-4 (1H). The LW-03 strain exhibits multiple plant growth-promoting traits, including the production of organic acids, ACC deaminase, indole-3-acetic acid (IAA), siderophores, and nitrogen fixation activity. The beneficial effects of the endophytic strain LW-03 on the growth of two lily varieties were further evaluated under greenhouse conditions. Our results revealed plant growth-promoting activity in inoculated plants relative to non-inoculated control plants. The broad-spectrum antifungal activity and multiple plant growth-promoting properties of Bacillus stratosphericus LW-03 make it an important player in the development of biological fertilizers and sustainable agricultural biological control strategies.

Abstract
The establishment of a benign system for the nanoparticle (NPs) synthesis, is a key in nanotechnology for the environmental and health care industries. Therefore, enrichment of novel biological systems for the green synthesis is in significant demand, to lift up these compounds in the biomedical industries. The present work, reports the green synthesis of ZnO NPs, employing a novel thermophile, identified as Bacillus haynesii (GeneBank: MG822851) isolated from the leaf of date palm plant (Phoenix dactylifera), as an eco-friendly nanobiofactory. Physiochemical characterization of ZnO NPs (50 ± 5 nm in size), was achieved by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), diffuse reflectance UV-Visible spectroscopy (DR UV-Vis spectroscopy), Thermogravimetry analysis (TGA), scanning electron microscopy (SEM) and transmissiom electron microscopy (TEM). The morphogenesis and antimicrobial activity of synthesized ZnO NPs, was studied by evaluating the minimum inhibitory/bactericidal concentration (MIC&MBC) against Escherchia coli (8 and 16 mg/mL) and Staphylococcus aureus (4 and 8 mg/mL), respectively. The present study encourages the use of B. haynesii for the green synthesis of ZnO NP. To the best of our knowledge, this is the first report on the study of thermophilic, B. haynesii for green synthesis of NPs in general and ZnO NPs in particular.

WASTE MANAGEMENT (NEW YORK, N.Y.) 2019; 93:63-71. [PMID: 31235058 DOI: 10.1016/j.wasman.2019.05.026] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Revised: 05/10/2019] [Accepted: 05/15/2019] [Indexed: 06/09/2023]
Abstract
The main goal of this work is the production of a biopesticide through solid-state fermentation of biowaste digestate inoculated with Bacillus thuringiensis (Bt) at pilot scale using different configurations of reactors. Fermentations were carried out using insulated and non-insulated, stirred and non-stirred reactors at different scales (10, 22 and 100 L) in order to assess the influence of the reactor configuration on the biopesticide production process. A maximum temperature of 60 °C was reached in 10-L insulated non-stirred reactors where increments of Bt viable cells and spores with respect to initial values of 1.9 and 171.6 respectively, were attained. In contrast, when temperature was regulated by using 22-L non-insulated stirred reactors the increment of viable cells and spores were 0.8 and 1.9, respectively, at a stable temperature of 27 °C. When the non-insulated stirred reactor was scaled up to 100-L, the increase of viable cells and spore counts were 1.2 and 3.8 respectively, with an average temperature of 28 °C. These results demonstrated that the election of a proper reactor configuration is important when considering the development of a new SSF process, especially when dealing with non-conventional substrates as digestate.
