“…However, several studies have also revealed something identical to this study that can cause the death of crustaceans L. vannamei and Daphnia magna (Sineva et al, 2009;Velmurugan et al, 2015). In addition, it was also disclosed as the causative agent of ice-ice in seaweed (Riyaz et al, 2021).…”

The supply of coconut crabs (Birgus latro Linnaeus, 1767) has been sourced from capture in the wild. Development efforts in aquaculture have succeeded in producing eggs. However, further development with larval maintenance failed because it was constrained by a low survival rate. This study aimed to identify the potential probiotic bacteria in coconut crabs. Coconut crab samples were collected from Moor Island, South Patani District, Central Halmahera Regency, North Maluku Province, Indonesia. The intestines of coconut crabs were taken as much as 1 g, then ground on a porcelain dish and added to Tri-Salt. The scouring liquid was taken in 0.1 ml and spread on a petri dish containing Nutrient Agar. The isolated used were marked with BL1, BL2, BL3, BL4, and BL5. Molecular identification was performed with sequencing and then analyzed using the Basic Local Alignment Search Tool (BLAST). The selection of isolates from the gastrointestinal tract of coconut crabs showed that the bacteria obtained were Enterobacter tabaci (BL1), Enterobacter hormaechei (BL2), Bacillus horneckiae (BL3), Pseudomonas stutzeri (BL4), and Acinetobacter variabilis (BL5). Further testing revealed that the bacteria A. variabilis (BL5) is a probiotic isolate in coconut crabs. Highlight Research The intestinal bacteria from coconut crabs identified were E. tabaci, E. hormaechei, B. horneckiae, P. stutzeri, and A. variabilis. The E. tabaci strain BL1, E. hormaechei strain BL2, B. Horneckiae strain BL3, and P. stutzeri strain BL4 are pathogenic bacteria. The A. variabilis strain BL5 is potential probiotics bacteria. The A. variabilis strain BL5 showed a better survival rate than other isolates.

“…Using established procedures for the acquisition of the carrageenan biopolymer, after algae extraction, polysaccharides are precipitated using ethanol or isopropanol [26,27]. In this way, the seaweed Furcellaria lumbricalis can be successfully used as a source for the development of a biodegradable force sensor matrix, in which electrically conductive elements (particles) are encapsulated at evenly distributed distances and approach each other corresponding to the applied force, thus, changing the electrical resistance [28,29].…”

The development of low-cost biodegradable pressure or force sensors based on a carrageenan and iron (III) oxide mix is a promising way to foster the spread of green technologies in sensing applications. The proposed materials are inexpensive and abundant and are available in large quantities in nature. This paper presents the development and experimental study of carrageenan and iron (III)-oxide-based piezoresistive sensor prototypes and provides their main characteristics. The results show that glycerol is required to ensure the elasticity of the material and preserve the material from environmental impact. The composition of the carrageenan-based material containing 1.8% Fe2O3 and 18% glycerol is suitable for measuring the load in the range from 0 N to 500 N with a sensitivity of 0.355 kΩ/N when the active surface area of the sensor is 100 mm2. Developed sensors in the form of flexible film have square resistance dependence to the force/pressure, and due to the soft original material, they face the hysteresis effect and some plastic deformation effect in the initial use stages. This paper contains extensive reference analysis and found a firm background for a new sensor request. The research covers the electric and mechanical properties of the developed sensor and possible future applications.

“…Therefore, it is meaningful to develop an efficient and controllable degradation method to prepare ultra-low molecular weight carrageenan with excellent biological activity so as to promotes the resource conservation and efficient use of carrageenan. Carrageenan is susceptible to various degradation techniques such as acid hydrolysis( Russo Spena et al, 2023 ), ultrasonic degradation ( Tecson, Abad, Ebajo Jr., & Camacho, 2021 ), oxidative degradation (T. Sun, Tao, Xie, Zhang, & Xu, 2010 ), and enzymatic degradation ( Riyaz et al, 2021 ), all of which can achieve degradation targets. Chemical hydrolysis is cost-effective and easy to operate.…”
