Summary: The effects of different Bacillus strains as initial indigenous species in biofloc system rearing Litopenaeus vannamei juveniles under low salinity conditions were investigated. The addition of B. cereus YB3 promoted biofloc formation, while B. subtilis NT9 improved shrimp growth performance. The specific growth rates and survival rates of shrimp were increased in the treatments with Bacillus strains.

Summary: This study aimed to investigate the effects of compound feed attractants on the growth performance, feed utilization, intestinal histology, protein synthesis, and immune response of Litopenaeus vannamei. The results showed that the diets supplemented with certain attractants promoted feed intake, growth performance, and antioxidant enzyme activity of the shrimp. However, some diets had negative effects on the hepatopancreas and intestine of the shrimp. The inclusion levels of certain attractants in the diets also had an impact on the weight gain and feed intake of the shrimp.

Summary: The commercial cultivation of Litopenaeus vannamei has greatly benefited the global shrimp industry in the past decade. However, there are no academic sources supporting its commercial farming in Bangladesh, which is an important player in the global shrimp industry. The declining shrimp industry in Bangladesh, caused by the low production of traditionally cultivated black tiger shrimp and its susceptibility to diseases, calls for immediate policy measures to introduce high-yielding Litopenaeus vannamei species.

Summary: This study investigated the effects of Pro-A on the growth performance, feed utilization, immune responses, and intestinal microbiota of whiteleg shrimp. The results showed that dietary supplementation with 0.1% Pro-A significantly improved the growth, protein efficiency ratio, feed conversion ratio, and survival rate of whiteleg shrimp. Additionally, Pro-A enhanced the digestive enzymes, hematological and immune profiles, and bacterial clearance efficiency. Furthermore, Pro-A reduced mortality after bacterial challenge. However, further research is needed to confirm these findings in commercial trials.

Summary: This study aims to identify the better stocking density of whiteleg shrimp in two intensive biofloc systems. The findings suggest that lower density (100/m^2) is associated with better growth performance, water quality, feed utilization, and gene expression of immune and growth-related genes when compared to high density (300/m^2) under biofloc system.

Summary: Bacteria generate and release extracellular reactive oxygen species (eROS), which significantly contribute to the natural ROS pool and play a crucial role in metabolic interactions of bacteria with their environment. Understanding the behavior of eROS-generating bacteria and its environmental implications is of great importance in the cycling of biogeochemical elements, transformation of organic matter, and regulation of antibiotic resistance genes.

Summary: Plastics and microplastics are widely present and accumulating in the environment, leading to increasing public attention. In addition to packaging plastics, materials from industries such as electronics, space and aviation are also accumulating, but receiving less attention. The production of degradable and biodegradable plastics is seen as a way to reduce environmental impacts, but enhancing the non-degradability of functional polymers is also a feasible option. Microbial colonization and deterioration pose significant challenges to these materials.

Summary: This study evaluated the keratinolytic activity of 37 strains of Trichophyton ajelloi and found that pigmented strains isolated from loamy soil were more efficient in degrading native feather keratin, while non-pigmented strains isolated from chernozem showed better abilities. The keratinolytic activity increased over time, as evidenced by the increase in extracellular keratinase activity and release of soluble proteins and peptides. Protease activity peaked in the first 7 days and again on day 28 of culture. The release of ammonium and sulfate ions, associated with an increase in pH, reached its maximum on day 21. Three pigment-producing strains were among the most active in releasing large amounts of ammonium and sulfate ions. The biodegradation of feather waste by Trichophyton ajelloi strains can be used to produce fertilizers suitable for plants with high sulfur requirements.
