Sib Sankar Giri 교수의 연구실은 수생 생물, 특히 고기류의 건강과 생장에 영향을 미치는 프로바이오틱스, 천연 첨가제 및 환경 오염 물질에 대한 저항성을 중심으로 연구를 진행하고 있습니다. 주로 균류, 박테리아 기반 프로바이오틱스 및 식물성 부산물(예: 바나나 껍질)을 활용한 수산양식의 지속 가능성과 면역력 향상을 목표로 하며, 중금속(lead) 등 환경 오염물질에 의한 스트레스에 대한 생리적 방어 기전을 규명하고 있습니다. 특히, 미생물, 항산화제, 천연 물질이 수생 생물의 생리적 기능과 면역 반응에 미치는 영향을 다각도로 분석하고 있습니다.

Labeo rohita fingerlings were fed for 60 days with basal diet (BD) or one of the following experimental diets: DI (BD + B. subtilis); DII (BD + B. subtilis + L. plantarum); DIII (BD + B. subtilis + P. aeruginosa) and DIV (BD + B. subtilis + P. aeruginosa + L. plantarum). Various growth and immune parameters were examined at 30 and 60 days postfeeding. The fish group fed DIV diet had better improvement (P < 0.05) in weight gain, specific growth rate (SGR) and feed conversion ratio (FCR) than the
Harmful effects of heavy metals are myriad. Lead (Pb) from soil and atmosphere contaminates water bodies and affects the aquatic animals. Our previous study confirmed the <i>in vitro</i> probiotic potential of <i>Lactobacillus reuteri</i> against Pb toxicity, but further investigation is necessary for gaining insights into the related protection mode. Therefore, in this study, we investigated the protective effects of the potential probiotic <i>L. reuteri</i> P16 against waterborne Pb exposure-i
This study aimed to isolate potential probiotic lactic acid bacteria from a traditional rice-based fermented beverage "bhaati jaanr" and to evaluate their role during preparation of the beverage. Among various isolates, <i>Lactobacillus plantarum</i> strain L7 exhibited satisfactory <i>in vitro</i> probiotic characteristics such as acid resistance and bile tolerance, cell surface hydrophobicity, auto-aggregation, antibiotic susceptibility, and antimicrobial activities. Therefore, performance of
To explore the feasibility of Musa acuminata (banana) peels as a feed additive, effects of banana peel flour (BPF) on the growth and immune functions of Labeo rohita were evaluated. Diets containing five different concentrations of BPF (0% [basal diet], 1% [B1], 3% [B3], 5% [B5], and 7% [B7]) were fed to the fish (average weight: 15.3 g) for 60 days. The final weight gain and specific growth rate were higher (P < 0.05) in the B5 group. The most significant improvements in immune parameters such
Multifarious applications of <i>Bacillus licheniformis</i> VS16-derived biosurfactant were explored. <i>Labeo rohita</i> fingerlings were injected intraperitoneally with 0.1 mL of phosphate-buffered saline (PBS) containing purified biosurfactant at 0 (control), 55 (S55), 110 (S110), 220 (S220), or 330 (S330) μg mL<sup>-1</sup> concentrations. Various immunological parameters and the expression of immune-related genes were measured at 7, 14, and 21 days post-administration (dpa). At 21 dpa, fish
