The dearth of information surrounding the utilization of Opuntia cladode alkaloids underscores a critical gap in understanding their pharmacological properties and therapeutic potential, emphasizing the need for further comprehensive investigations. The present study aims to investigate the in vitro anti-inflammatory, anticoagulant, and antimicrobial activities of alkaloïds belonging to young cladodes (nopals) of inermis Algerian Opuntia ficus indica. The assessed alkaloïds showed a moderate anti-inflammatory effect regarding the BSA protein protection with a maximum of 51.04±1.84 % compared to 84.22±2.38 % for Diclofenac sodium as a positive standard. However, their stabilization of red blood cells membrane against induced hemolysis was greater than Diclofenac (52.38±2.01 % vs 48.97±2.73 %). The two assays had a significant correlation (< 0.05) of 0,968. Nopal alkaloïds extended the coagulation time (1.24 fold) by significantly affecting the exogenous pathway PT only, whilst they were ineffective against the endogenous pathway APTT. Conversely, Algerian nopal alkaloïds had neither bacteriostatic nor bactericide influence at 2 mg ml-1 on Candida albicans yeast or the six tested pathogenic bacterial strains. In perspective, the purification of these Opuntia nopal alkaloïds and understanding their accurate mechanism of action are clearly the strategic steps to illustrate their overall curative potential.

Whey, a by-product of cheese industry, poses environmental challenges when discharged untreated. This study aimed to mitigate whey pollution and transform it into value-added products using black soldier fly larvae (BSFL). By investigating whey effects on BSFL growth and performance, an innovative waste management strategy was explored. The five-old-day larvae were fed with four diets; dry spent coffee ground (SCG) as the control diet, while SCG wetted with acid, sweet and fermented whey were the test diets. The results showed that whey types increased significantly (p < 0.05) BSFL growth compared to the control, the dry weight (53.83±0.49 Vs 25.10±0.18 mg/larva), growth rate (1.59±0.06 Vs 0.44±0.01 mg/day) and survival rate (78.83±1.25 Vs 68.50±1.5 %) of larvae and reduced their development time (28.00±01 Vs 37.00±01 day). Furthermore, mixing SCG diet with whey enhanced positively their performance by increasing the waste reduction (26.73±0.81 Vs 16.87±0.37 %), waste reduction index (0.85±0.03 Vs 0.45±0.01 %/day), approximate digestibility (36.49±1.52 Vs 20.29±0.53 %) and bioconversion rate (17.94±0.47 Vs11.65±0.52%). Adding whey to SCG diet increased protein content of BSFL (40.11% vs. 34.18%) and reduced fat (36.06 vs. 37.87 %) in dry mass. Whey also improved the composition of frass by increasing the phosphorus and total nitrogen levels. This approach demonstrates a sustainable solution for dairy industries waste, contributing to the circular economy and offering potential applications in animal feed and fertilizer production.
