Probiotic fermented milk can lower the incidence rate of hypertension and is beneficial to the regulation of the intestinal microecology. However, the underlying molecular mechanism remains elusive. Here, we evaluated the role of the gut microbiota and its metabolites in the antihypertensive effect of milk fermented by the Lactiplantibacillus plantarum strains SR37-3 (PFM-SR37-3) and SR61-2 (PFM-SR61-2) in Ng-nitro-L-arginine methyl ester induced hypertensive rats. The results showed that PFM-SR37-3 and PFM-SR61-2 intervention significantly lowered the blood pressure (BP) of NG-nitro-L-arginine methyl ester induced hypertensive rats and attenuated renal injury. In particular, long-term administration of PFM inhibited a progressive elevation in SBP (170.22 ± 8.40 and 133.28 ± 6.09 by model group and PFM-SR37-3 treated model group, respectively, at the end of the 4 weeks; p < 0.01 PFM-SR37-3 treated model group versus model group) and DBP (133.83 ± 5.91 and 103.00 ± 6.41 by model group and PFM-SR37-3 treated model group, respectively, at the end of the 4 weeks; p < 0.01 PFM-SR37-3 treated model group versus model group). PFM-SR37-3 and PFM-SR61-2 reshaped the gut microbiome and metabolome, and especially regulated the metabolic levels of L-phenylalanine, L-methionine and L-valine in the intestine and blood circulation. The analysis of the target organ’s aortic transcriptome indicated that the protective effects of PFM-SR37-3 and PFM-SR61-2 were accompanied by the modulation of the BP circadian rhythm pathway, which was conducive to cardiovascular function. Vascular transcriptomic analysis showed that circadian rhythm and AMPK might be potential targets of hypertension. In addition, the ACE inhibition rates of Lactiplantibacillus plantarum SR37-3 and Lactiplantibacillus plantarum SR61-2 in vitro were 70.5% and 68.9%, respectively. Our research provides new insights into novel and safe options for hypertension treatment.

“…Tujuh senyawa VFAs paling umum ditemukan dalam bioreaktor anaerobik adalah asam format, asam asetat, asam propionat, asam butirat, asam valerat, asam iso-valerat dan asam kaproat (Possente et al, 2022). Kehadiran VFAs dalam reaktor anaerob mengindikasikan adanya aktivitas mikroorganisme asidogen (Strazzera et al, 2021).…”

Minyak sawit merupakan salah satu komoditas unggulan, dan Indonesia merupakan salah satu produsen kelapa sawit terbesar di dunia. Limbah padat yang dihasilkan dari aktivitas industri kelapa sawit adalah Tandan Kosong Kelapa Sawit (TKKS). Kandungan selulosa di dalam TKKS dapat dimanfaatkan sebagai substrat peruraian anaerob untuk menghasilkan volatile fatty acids (VFAs). Pada penelitian ini digunakan pengolahan awal secara kimia (NaOH 8% w/V) untuk delignifikasi TKKS sebelum diproses dalam fermentasi anaerob. Digested cow manure (DCM) digunakan sebagai inokulum. Pengoptimalan proses untuk menghasilkan VFAs merupakan tantangan karena VFAs merupakan produk intermediet di jalur metabolik peruraian anaerob menuju pembentukan metana. Penelitian ini mengkaji potensi VFAs dari TKKS dengan menvariasikan suhu terhadap proses fermentasi anaerobik TKKS untuk memproduksi VFAs di reaktor batch. Variasi suhu yang dikaji adalah kondisi mesofilik (29 ℃) dan termofilik (55 ℃). Prediksi potensi VFA dapat dihitung dengan rumus molekul empiris dengan pendekatan stoikiometri reaksi. Hasil perhitungan, potensi VFA dari TKKS adalah sebesar 44,5x10-2 mg.mgTS-1. Eksperimen menujukkan kondisi termofilik menghasilkan VFAs 60% lebih tinggi dibandingkan mesofilik, terlihat dari percent completion RT mencapai 59% dan lebih mendekati potensi teoritis.

“…Groups K1, A1, A2, A3, A4 and A5 exhibited the peak values of 3.10, 1.50, 3.06, 5.59, 5.55 and 13.23 g/L on the 13th day, respectively. Much higher levels of VFAs have been reported for proteins and starches than other materials such as cellulose during the fermentation of putrefying waste (Strazzera et al, 2021). Therefore, the microorganisms mainly degrade the protein and starch in the substrates leading to the accumulation of acids, especially in A5, resulting in inhibited methanogenesis (see daily methane production pro le in Section 3.1).…”
