The development and implementation of new and safe means of treating subclinical mastitis (SM) in the production process remains a pressing problem. Our study aimed to investigate the therapeutic effect of the Bacillus megaterium NCH 55 strain on cow SM. All animals with signs of SM were fed with a basic diet with probiotic's addition of 15 g/per day. The experiment was conveyed in 30 consecutive days. Milk and blood were collected on the 7 th , 15 th , and 30 th day of the experiment. Daily milk yield was increased by 32.2% and somatic cell count was decreased from 290.00±32.12 to 96.80±39.03 ths/cm 3 . A decrease in inflammation was indicated by a decrease in POM 370 (by 2.2 times) and POM 430 (by 2.8 times). No significant changes in the blood serum indices of cows were observed. A probiotic's positive effect has been established on the treatment of SM. The probiotic B. megaterium NСH 55 can be considered as an alternative to antibiotics and other chemotherapeutic drugs for treating SM in cows.

Abstract. Ginting CN, Piska F, Harmileni, Fachrial E. 2023. Molecular identification of thermophilic bacteria with antimicrobial activity isolated from hot springs in North Sumatra, Indonesia. Biodiversitas 24: 752-758. Microorganisms such as thermophilic bacteria are promising sources of antimicrobial compounds due to their abundance, which has yet to be widely investigated. Therefore, this study aims to identify thermophilic bacteria isolated from natural hot springs, Sidebuk Debuk, in North Sumatra, Indonesia. The bacteria were isolated from sediments and hot springs water. Isolated 10 bacteria were characterized and identified based on their morphological and biochemical properties, which included gelatinase activity, motility, citrate utilization, triple sugar iron agar test, catalase test, cell shape, color, and Gram staining. Antimicrobial activity was tested using the disc diffusion method against Escherichia coli and Staphylococcus aureus. The most potential isolates were identified molecularly by amplification of 16S rRNA genes using universal primers. The sequences result were trimmed and assembled using BioEdit and submitted to BLAST to determine the homology of the bacteria. The isolate ITU9 was identified as Bacillus megaterium and exhibited the best antimicrobial activity with an inhibition zone of 9.5 mm against S. aureus during 72 h of incubation. This research showed that the thermophilic B. megaterium strain ITU9 was successfully isolated from Sidebuk Debuk hot springs and had stable antimicrobial activity for 72 h against E. coli and S. aureus.

In response to climate change, the nature of endophytes and their applications in sustainable agriculture has attracted the attention of academia and agro-industries. We focused on the endophytic halophiles of the endangered Taiwanese salt marsh plant,Bolboschoenus planiculmis, and evaluated the functions of the isolates throughin plantasalinity stress alleviation assay usingArabidopsis. An endophytic strainPriestia megateriumBP01R2 that could promote plant growth and salinity tolerance was further characterised through multi-omics approaches. The transcriptomics results suggested that BP01R2 could function by tuning hormone signal transduction, energy-producing metabolism, multiple stress responses, etc. In addition, a cyclodipeptide, cyclo(L-Ala-Gly), identified by metabolomics analysis was later confirmed to contribute to salinity stress alleviation in stressed plants by exogenous supplementation. Here we provide a new perspective on host-microbe interactions in the wetland biome based on the multi-omics investigation and mixotrophic character of BP01R2. This study revealed a biostimulant-based plant-endophyte symbiosis with potential application in sustainable agriculture and facilitated our understanding of those enigmatic cross-kingdom relationships.
