Hydroponic food production in greenhouses is challenged by reduced exposure to ultraviolet (UV) light and beneficial soil microorganisms, which predisposes plants to antioxidant deficiencies and disease susceptibility. The objective of this study was to investigate the effects of UV light exposure and compost tea treatment on hydroponically grown plants. Garnet Giant mustard greens were hydroponically grown in both indoor and outdoor greenhouse settings, with and without UV light blocking and supplementation of compost tea. Plants grown outside in greenhouses produced more dry mass than those grown indoors. Compost tea supplementation boosted nitrogen and mineral accumulations in the absence of UV-blocking. Increased UV exposure resulted in more red pigmentation and higher antioxidant activities of the mustard greens, while compost tea supplementation reduced antioxidant activities. Compost tea treatment increased beneficial bacteria and decreased fungal pathogens. Overall, exposure to UV radiation and beneficial microorganisms improved the performance and nutrient profile of the mustard greens.

“…Members of the Brevibacillus genus are rod-shaped, Gram-positive or Gram-variable firmicutes that belong to the Paenibacillaceae family ( De Vos et al, 2011 ; Panda et al, 2014 ). The endospore-forming Brevibacillus species were genetically reclassified as a distinct genus from the Bacillus brevis (B. brevis) cluster in 1996 ( Ray et al, 2020 ), and now consists of 29 validly published species (available at: https://lpsn.dsmz.de/genus/brevibacillus ). Members of this genus are widely distributed in nature, occurring in soil, plants, aquatic environments, intestinal tracts of insects, and animals ( Panda et al, 2014 ; Yang and Yousef, 2018 ).…”

Underexplored bacteria as reservoirs of novel antimicrobial lipopeptides

Natural products derived from microorganisms play a prominent role in drug discovery as potential anti-infective agents. Over the past few decades, lipopeptides produced by particularly Bacillus, Pseudomonas, Streptomyces, Paenibacillus, and cyanobacteria species, have been extensively studied for their antimicrobial potential. Subsequently, daptomycin and polymyxin B were approved by the Food and Drug Administration as lipopeptide antibiotics. Recent studies have however, indicated that Serratia, Brevibacillus, and Burkholderia, as well as predatory bacteria such as Myxococcus, Lysobacter, and Cystobacter, hold promise as relatively underexplored sources of novel classes of lipopeptides. This review will thus highlight the structures and the newly discovered scaffolds of lipopeptide families produced by these bacterial genera, with potential antimicrobial activities. Additionally, insight into the mode of action and biosynthesis of these lipopeptides will be provided and the application of a genome mining approach, to ascertain the biosynthetic gene cluster potential of these bacterial genera (genomes available on the National Center for Biotechnology Information) for their future pharmaceutical exploitation, will be discussed.

“…Brevibacillus is a Gram-positive or Gram-variable, rod-shaped bacterium that can form endospore. It is reclassified from Bacillus brevis based on 16S rDNA sequence, and there are currently 23 species in this genus [17]. This bacterial strain is widely found in diverse environments, including soil, plants, and seawater [18].…”

Identification and Characterization of a Potential Antimicrobial Peptide Isolated from Soil Brevibacillus sp. WUL10 and Its Activity against MRSA Pathogens

et al. 2022

Methicillin-resistant Staphylococcus aureus (MRSA) is a severe threat to public health globally. The development of novel agents has encountered the repeated mechanism of drug resistance. This study aimed to investigate an anti-MRSA substance isolated from a promising soil bacterium. The result showed that an isolate (WUL10) was in the Brevibacillus genus. The minimum inhibitory concentration (MIC) of the purified substance was 1 µg/mL against S. aureus TISTR 517 and MRSA strains. This substance showed the bactericidal effect at the concentration of 1–2 µg/mL against these bacterial indicators. The activity of the substance retained more than 95% when encountering high temperatures and a wide range of pH, but it was sensitive to proteolytic enzymes and SDS. It was identified as a novel antimicrobial peptide (KVLVKYLGGLLKLAALMV-COOH) with the predicted structure of α-helix. The substance could rupture the cell wall of the tested pathogen. MIC and MBC of the synthesized peptide were 16 and 64 µg/mL, respectively. The difference in the activity between the isolated and synthetic peptides might be from the synergistic effects of other AMPs in the purified substance. This novel AMP would provide an advantage for further development of anti-MRSA substances to manage the situation of antibiotic resistance.
