Inorganic nutrient application in Kappaphycus seaweed farming has been a practice in the southern Philippines for the past years. To investigate the inorganic nutrient’s influence on the number and assemblage of Vibrio and heterotrophic marine bacteria and on the presence of ice-ice disease-inducing bacteria in Kappaphycus striatus, a field experiment was conducted using ammonium phosphate (16-20-0) fertilizer at high concentration (HC, 8.82 g L–1), low concentration (LC, 0.01 g L–1), and control (C, 0.00 g L–1). Vibrio (VCs) and heterotrophic marine bacterial counts (HMBCs) were found similar among treatments. Based on 16S rRNA gene sequencing, isolates from source K. striatus, nutrient-enriched K. striatus (HC, LC, and C), farm seawater, and fertilizer solutions were identified as Vibrio alginolyticus (three strains), V. parahaemolyticus, V. brasiliensis, V. harveyi, Gilvimarinus chinensis, and species related to Bacillus sp. ST7, Psychrobacter sp. ST8, Enterococcus sp. ST5, Oceanobacillus sp. ST9, and Paracoccus sp. ST10. Bacillus sp. ST7 and Oceanobacillus sp. ST9 were unique and only present in HC and LC. The agarolytic activity of G. chinensis, isolated from all samples, suggests that it is an ice-ice disease-causing bacterium. The microbial community dynamics of farmed K. striatus, when enriched with inorganic nutrients, may pave way in addressing the occurrence of ice-ice disease.

Diseases and pests are major limiting factors to aquaculture production, 1 including seaweeds, 2 prompting global action to improve biosecurity and knowledge of important yield-limiting pathogens affecting sustainable production, both now and in the future. 3,4 Seaweeds comprise almost 30% of global aquaculture production by volume. 5 Production of the carrageenophyte red algal genera Kappaphycus and Eucheuma (collectively known as eucheumatoids) has increased rapidly in the past decade, accounting for 33.99% of global aquatic plant cultivation in 2018. 5 Eucheumatoids are commercially cultivated for production of carrageenans, polysaccharides widely used in the pharmaceutical, cosmetic and food industries.Much of this cultivation occurs in South-East Asia, particularly

“…Seaweed also has various secondary metabolite compounds that have potential in the treatment of various diseases caused by pathogenic microbes. The use of seaweed bioactive compounds has begun to be developed to replace the use of synthetic chemical raw materials, which are harmful to humans and the environment (Nasmia, 2014). Currently, seaweed processing is carried out in the industry.…”

The comparison of the concentration of Kappaphycus alvarezii seaweed is estimated to affect the total bacteria and yeast during the kombucha production process. The carbohydrate content in seaweed can be one of the factors for the formation of nata as a parameter for the success of making kombucha, as well as its effect on nutrition for bacterial and yeast growth. This study aims to determine the effect of comparing the concentration of seaweed on the total bacteria and yeast kombucha Kappaphycus alvarezii. The method used in this study is an experimental method with a completely randomized design (CRD) with six treatments and 4 replications. The results of this study indicate that the comparison of the concentration of Kappaphycus alvarezii seaweed affects the total bacteria and yeast during the kombucha making process. The total bacteria test showed that the total bacteria increased until the 3rd day and the highest total yield was found in the control treatment, which was 1,6x107 CFU/ml on the 3rd day. Then the total yeast also increased until the 3rd day and the highest yield was found in the control treatment of 2,3x107 CFU/ml.
