The SSF of the novel marine tunicate-associatedMicrococcusunila18D36-A2 on shrimp shell medium has never been re-ported before. Our knowledge of the ability of microorganismsto manufacture enzymes capable of chitin breakdown fromSSW into derivative chemicals through SSF is improved bythis work. As indicated by this study, actinomycetes derivedfrom tunicates exhibit robust growth on selective media com-prised of SSW during the fermentation process, leading toglucosamine production. This information is vital for futureresearch on developing medicinal preparations from naturalwaste products.

The solid-state fermentation (SSF) of the novel marine tunicate-associated *Micrococcus unila* 18D36- A2 on shrimp shell medium has not been previously documented. This research advances our
understanding of how microorganisms can produce enzymes that break down chitin from shrimp shell waste (SSW) into valuable chemical derivatives through SSF. The study shows that actinomycetes derived from tunicates exhibit strong growth on selective media made from SSW during the fermentation process, resulting in the production of glucosamine. This finding is important for future research focused on developing medicinal products from natural waste materials.

Based on the research findings, the following conclusions can be drawn: The highest methane gas production percentage in situ was observed in sample 10, which contained 3g of Ni, 1g of Al, and 2g of Fe, yielding 10.07%. The highest CO2 conversion percentage was also recorded in sample 10, with the same amounts of Ni, Al, and Fe, resulting in 2.70%. Additionally, an increase in Ni concentration was found to contribute to higher production levels.

This study evaluated a new coupling system for low rotation and minimal power transmission from an electric drive to a propeller in fish ponds, revealing that the bend angle (ɸ) significantly affects performance—establishing a maximum operational angle of 25 degrees for effective power and rotation transmission—and underscoring the necessity of considering bend angles in clutch design;
the introduction of grease reduced noise byapproximately 2%, highlighting lubrication's critical role in enhancing system efficiency and minimizing noise; while brass offers corrosion resistance and reduced noise, its lack of strength for high-load applications points to carbon steel with medium carbon content as a better material choice, offering improved strength, wear resistance, and structural stability; the study underscores the need to assess factors like wear, resilience to dynamic loads, and friction characteristics, recommending further research into energy losses and
environmental influences to optimize transmission system performance in aquatic environments.

This study assessed a new coupling system for low-speed rotation and minimal power transmission from an electric drive to a propeller in fish ponds. The results revealed that the bend angle (ɸ) plays a
significant role in system performance, establishing that an optimal operational angle of 25 degrees is necessary for effective power and rotation transfer. The study also highlighted the importance of considering bend angles when designing clutches. The introduction of grease resulted in a reduction of noise by approximately 2%, emphasizing the importance of lubrication in improving system efficiency and reducing noise. While brass offers advantages in corrosion resistance and noise reduction, its insufficient strength for high-load applications suggests that medium-carbon carbon steel is a better material choice due to its superior strength, wear resistance, and structural stability. The research stresses the need to evaluate factors such as wear, resilience to dynamic loads, and friction
characteristics, and recommends further investigations into energy losses and environmental factors to optimize transmission system performance in aquatic settings.
