Abstract

Hepatocellular carcinoma (HCC) is among the most prevalent and deadly cancers globally, with limited treatment options and poor prognosis in advanced stages. This study evaluated the therapeutic potential of methanol leaf extract of Annona senegalensis against diethylnitrosamine (DEN)-induced HCC in Wistar rats and investigated its antibacterial properties. Thirty-six male albino rats were allocated into six groups: Group I (normal control) received no treatment; Group II (negative control) was induced with HCC using DEN (50 mg/kg b.w., intraperitoneally) weekly for three weeks without therapy; Group III (positive control) received DEN followed by silymarin (100 mg/kg b.w.); while Groups IV, V, and VI received DEN followed by A. senegalensis extract at 200, 400, and 600 mg/kg b.w., respectively, administered orally for 14 days. Biochemical analysis showed that the extract significantly (p < 0.05) ameliorated DEN-induced hepatotoxicity, with the 400 mg/kg dose most effective in reducing AST (48.71 ± 1.21 IU/L) and ALT (20.74 ± 1.06 IU/L) compared to the negative control (69.52 ± 0.88 IU/L and 54.97 ± 1.54 IU/L, respectively). Hepatic synthetic function was restored, as indicated by increased total protein (6.37 ± 0.13 g/L) and albumin (5.11 ± 0.10 g/L). Histopathological analysis confirmed marked architectural recovery with reduced necrosis and inflammatory infiltration. The extract also demonstrated significant antibacterial activity, exhibiting dose-dependent inhibition zones against Gram-positive (Staphylococcus aureus, Bacillus subtilis) and Gram-negative (Escherichia coli, Pseudomonas aeruginosa) bacteria, with effects comparable to standard antibiotics. These findings suggest that A. senegalensis leaf extract exerts hepatoprotective effects—likely through antioxidant, anti-inflammatory, and antiproliferative mechanisms—while also offering broad-spectrum antimicrobial benefits. The 400 mg/kg dose emerged as the most effective, highlighting its promise as a cost-effective complementary therapy for managing HCC and bacterial infections, particularly in resource-constrained settings. Further research should focus on isolating and characterizing the bioactive compounds and elucidating their mechanisms of action.

Abstract

Microbial production of antimicrobial compounds remains a fundamental area of biotechnology and pharmaceutical development, and its efficiency is strongly influenced by the carbon source available in the growth medium, which functions not only as an energy substrate but also as a regulator of microbial metabolism and secondary metabolite synthesis. This study aimed to evaluate the effects of five carbon sources—glucose, lactose, sucrose, starch, and glycerol—on microbial biomass yield, strain-specific growth preferences, metabolic compatibility, antimicrobial potency, inhibition zones, and bioactive metabolite production. Seven microbial strains, including Streptomyces, Bacillus, Pseudomonas, Actinomyces, and Clostridium, were cultured in media supplemented with each carbon source. Biomass yield was measured gravimetrically, growth rate indices were calculated on a scale of 0–10, antimicrobial potency was assessed using zone of inhibition assays against S. aureus, E. coli, P. aeruginosa, and K. pneumoniae, and metabolite yield was quantified in mg/L using spectrophotometric analysis. All experiments were conducted in triplicate. The findings showed that glucose produced the highest biomass yield and growth rates across all strains, with Bacillus and Pseudomonas each scoring 10. Lactose demonstrated selective effectiveness, particularly for Streptomyces, whereas sucrose supported moderate growth and selective antimicrobial activity. In contrast, starch and glycerol consistently resulted in low biomass production and minimal antimicrobial potency. The zone of inhibition results further confirmed that glucose and lactose were the most effective substrates, with inhibition zones exceeding 20 mm. Similarly, metabolite yield was highest with glucose (120 ± 5.4 mg/L) and lactose (115 ± 4.9 mg/L), while glycerol produced the lowest yield (30 ± 1.5 mg/L). The study concludes that carbon source selection plays a critical role in microbial proliferation and antimicrobial compound production, with glucose and lactose emerging as the most suitable substrates for broad-spectrum antimicrobial activity and high metabolite yield. These findings contribute practical evidence for optimizing fermentation strategies according to microbial metabolic profiles to enhance antimicrobial synthesis.
