Summary: The widespread use of nanoparticles leads to their presence in wastewater and landfills, posing a potential risk to the environment. However, the harmfulness of nanoparticles is still not well understood. This study examines the genotoxicity of aluminum oxide nanoparticles (Al2O3 NPs) using Escherichia coli bacteria and erythrocytes of Cyprinus carpio. The results indicate that Al2O3 NPs can potentially cause changes in the genetic material of the bioindicators.

Summary: Concern on the toxicity of final wastewater generated by the petroleum refining industry has increased due to potential health threats. This study found that petroleum refinery wastewater is mutagenic and genotoxic, posing risks to the environment. The substances responsible for this toxicity were identified as organic compounds and heavy metals present in the wastewater.

Summary: This study evaluated the effects of dietary supplementation with L-carnitine on growth performance, gut and muscle histological parameters, blood hematology, plasma biochemical parameters, and antioxidant enzymes in Nile tilapia juveniles. Results showed that supplementation with L-carnitine improved growth performance and reduced lipid content in the filet, while also increasing the activity of the enzyme catalase in the liver. Different inclusion levels of L-carnitine had varying effects on weight gain, fat deposition, and triacylglycerol in the fish.

Summary: The study revealed that the digestive tract exhibited more significant antioxidant responses to microplastic contamination compared to the gills. The levels of SOD and MDA in the gills were directly affected by the abundance of microplastics, while the levels of SOD and CAT in the digestive tract were directly influenced by the quantity of microplastics.

Summary: A raw starch digesting ?-amylase, AMY-T, was identified in the intestine of Nile tilapia. It showed high catalytic efficiency and adsorption towards various carbohydrates, with stable endo-activity under a wide range of pH and solvent conditions. Characterization revealed the end products of raw starch hydrolysis and the catalytic attack pattern on starch granules, suggesting high potential for industrial use.

Summary: The study experimentally assessed Nile tilapia as a potential paratenic host for Toxocara spp. It was found that despite shedding viable eggs through the gastrointestinal tract, tilapias may not play a role as a suitable paratenic host. Therefore, the risk of zoonotic transmission through fish meat consumption is low.

Summary: The study found that propofol has longer induction and anesthesia duration compared to eugenol in fish anesthesia, while also having a faster recovery rate. In terms of hematological indices, the propofol group showed a transient increase compared to the eugenol group. However, there were no significant changes in other indicators such as leukocytic counts between the two groups. During anesthesia, both propofol and eugenol groups showed a temporary increase in glucose and cortisol levels, which returned to baseline levels during the recovery period.

Summary: Biodiesel production from fish oil extracted from Nile tilapia waste was optimized using homogeneous alkaline transesterification with ethanol and potassium hydroxide as catalyst. The best condition achieved a biodiesel yield of 92% with KOH 2%, oil:ethanol molar ratio of 1:12, and reaction time of 4 hours, resulting in a product with low acid value, low kinematic viscosity, and low production cost. TLC and FTIR analyses confirmed the conversion of triglycerides into biodiesel, and gas chromatography showed no significant differences in fatty acid profiles between crude oil, bleached oil, and biodiesel.

Summary: This study presents the results of the first ever research on biodiversity and biogeography of marine benthic diatoms from coral reefs in Indonesia, revealing a high abundance and diversity of diatoms. Biodiversity indices were higher in Indonesia compared to other tropical oceanic islands, with habitat type playing a more significant role in taxonomic composition than geographic factors. Cosmopolitan taxa were dominant in relative abundance, while species richness was higher in tropical and local forms. Many taxa were identified only at the genus level, potentially indicating new species.

Summary: Cocconeis dapalistriata, originally classified as a member of the genus Cocconeis, is re-examined due to its unique ultrastructure. It shows differences in the valvocopulae compared to Cocconeis and shares similarities with Amphicocconeis. The raphe valve striae are similar to those in Cocconeis, but the sternum valve has distinct features, leading to the proposal of a new genus Upsilococconeis.
