Lipase and protease present in cell-free fractions of thermophilic Bacillus sp. cultures were analyzed by polyacrylamide gel (PAG) electrophoresis. After run, the gel is electrotransferred to another PAG copolymerized with glycerol tributyrate, olive oil, and gelatin. This multi-substrate gel was incubated first for lipase detection, until bands appeared, and then stained with Coomassie for protease detection. Advantages of this sequential procedure are the detection of two different enzyme activities on a single PAG, beside time and resource saving.

The effect of different feeding habits on gut morphology and digestive function has been intensively studied during the last decades but sympatric closely related fishes are relatively rare objects of such studies. In the present study, we have identified both morphological and physiological changes in the digestive system of a sympatric pair of whitefish represented by "normal" Coregonus lavaretus pidschian (benthivorous) and "dwarf" C. l.

The excessive use of antibiotics in mariculture has surpassed permitted levels, leading to their release into surrounding waters and accumulation in cultured organisms, which poses risks to human health and highlighting the urgent need for alternatives to reduce antibiotic use. Therefore, the present study aimed to test four microbes including Debaryomyces hansenii, Ruegeria mobilis, Lactobacillus plantarum and Bacillus subtilis, on lowering Vibrio, promoting population increase and survival of Brachionus plicatilis. The digestive enzymes activity including α-amylase, lipase and protease, microbial retention and biochemical composition of rotifers were analyzed.

Development of bio-supported photocatalysts has become a pressing need in the field of environmental remediation. This work reports the synthesis of bio-enzyme (from banana peels) inherited (ZnO/g-CN) nanocomposite by simple soft chemical method and its photocatalytic degradation ability against the mixed dye (Methylene blue (MB) + Rhodamine-B (RhB)) under UV irradiation. Synthesized nanoparticles were characterized using experimental techniques XRD, FESEM, TEM, EDAX, XPS, UV-vis-NIR spectroscopy and FTIR.
