These benefits are due to their broad spectrum of antimicrobial activity and mode of action, their ability to secrete these important peptides in large amounts (g/L level) in a culture medium, and the ubiquitous nature of producing strains. It is well known that fish farming industries are challenged with pathogenic infection, indiscriminate antibiotic use, and now linked to antibiotic resistance of pathogens due to poor sewage disposals and persistence in nature. To overcome these challenges and the quest to stop the unregulated use of conventional antibiotics in fish farming industries has encouraged studies toward more eco-friendly options such as probiotics and associated bacteriocins with antimicrobial potential. Therefore, this review summarized and discussed recent studies on the effectiveness of Bacillus strains probiotic application in fish farming, emphasizing the importance of their proper characterization, extended field trials and the need for specifications in the selection criteria of the potential Bacillus probiotic strains of interest before further investigations, approvals and registrations.

Different varieties of rice landraces are grown in Nigeria; Abakaliki rice is grown in Ebonyi State and consumed in almost all parts of the country. This study evaluated the fatty acid composition of parboiled and un-parboiled Abakaliki rice landraces. The GC-MS analysis revealed that myristic, myristoleic, oleic, linoleic and vaccenic fatty acids were the most dominant in the rice landraces. In addition, all study samples contain a total amount of vaccenic (34.45%), oleic (33.36%) and myristic (21.68%) fatty acid, however myristoleic (3.3%) and linoleic (7.5%) fatty acid is in low amount. This study reveals that these fatty acids are 63.82% higher in the parboiled rice cultivars than in the un-parboiled rice.
