Summary: This study investigated the effects of bacterial lysates on the differentiation of 3T3-L1 pre-adipocytes. The results showed that these lysates can inhibit lipid droplet accumulation and affect the expression of adipogenic-related transcription factors and molecules. These findings suggest that bacterial lysates may have anti-adipogenic effects.

Summary: The function of the Aat gene was studied in Pediococcus acidilactici FAM 18098 through gene knockout experiments. It was found that Aat plays a crucial role in the synthesis of 3-phenyllactic acid and 4-hydroxyphenyllactic acid, as well as the catabolism of phenylalanine. Pyruvic acid was identified as an amino group acceptor in transamination reactions in P. acidilactici. This study reveals the important metabolic function of Aat in P. acidilactici.

Summary: This study found that four different Pediococcus acidilactici strains showed some improvement in the time to the first black-stool defecation and gastrointestinal transit rate in constipated mice. There were significant differences in the gastrointestinal regulatory peptides and gut microbiota among the different groups, especially with the bacteriocin-producing strains. Overall, while constipation-related symptoms were only mildly alleviated, the administration of these strains effectively regulated the gut flora and potentially provided health benefits to the host.

Summary: This study aimed to investigate the effects of fermented feed on the growth performance and gut microbiota of nursery pigs. The results showed that the fermented feed improved daily weight gain and significantly increased the concentration of acetate, butyrate, and total short-chain fatty acids in the feces. In addition, the addition of the fermented feed led to significant changes in the structure and membership of the gut microbiota. The study found that the fermented feed enriched beneficial bacteria that produce short-chain fatty acids, and some of these bacteria also had anti-inflammatory and other beneficial functions.

Summary: The experiment showed that feeding crayfish with a diet containing 20 g/kg of encapsulated Na-propionate resulted in the best growth performance and highest survival rate. This diet also led to increased enzyme activities in the crayfish gut. Optimum dietary levels of encapsulated Na-acetate, Na-butyrate, Na-lactate and Na-propionate were suggested to be 30.7, 31.8, 31.4 and 33.5 g/kg, respectively, for crayfish reared in culture conditions based on regression analysis.

Summary: The compensatory growth response (CGR) was observed in both sobaity and yellowfin seabream juveniles following a period of feed restriction, with the sobaity exhibiting a full CGR during the refeeding period. Different physiological parameters, including body weight, feed conversion ratio, and antioxidant enzyme activities, showed varied responses to the feed restriction among the two species, indicating that increasing the severity of feed restriction may lead to oxidative stress and compromise the health condition of the fish.

Summary: The aim of this study was to enrich high-performance microbial communities for the removal of ammonium and nitrite from aquaculture water. Ammonium oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) were enriched from different environmental water samples and adapted to different temperatures. The microbial communities containing Nitrosomonas oligotropha and Nitrobacter winogradskyi showed the highest removal activity at all temperatures and do not contain any pathogenic bacteria. Using the enriched microbial communities, a significant improvement in the removal of ammonium and nitrite was achieved compared to commonly used communities in biofilters.

Summary: This study investigated the effects of different levels of DHA enrichment on the growth, survival, fatty acid profile, digestive enzymes, antioxidant parameters, and histology of yellowtail clownfish larvae. The results showed that a DHA concentration of 6% in rotifer enrichment was sufficient to fulfill the DHA requirements and maximize the growth rate of the larvae. High levels of DHA (36%) decreased larval survival, while the DHA12 group had the lowest growth due to lower digestive enzymes and antioxidant activities.

Summary: This study evaluated the effects of humic acid (HA) on nutrient removal efficiency of aquatic duckweed plants and the growth performance and hematological properties of Nile tilapia fish. The results showed that increasing the concentration of HA improved the removal efficiency of ammonia nitrogen and phosphorous by the duckweed plants, as well as the growth performance of the fish. Different concentrations of HA had no adverse effect on the hematological properties of Nile tilapia. Therefore, adding HA to water can effectively improve water quality and fish growth performance in a water recirculating system.
