“…The anthropogenic factors mainly ballast water discharge along with tides and riverine discharge can alter the microbial community structure as a response thus altering the functional characteristics of the port and is a cause for concern (Kuchi et al., 2023). The species present in older ballast water are tougher and thus could have the potential to proliferate in non‐native environments (Ardura et al., 2021). Various factors such as salinity, temperature, dissolved inorganic nutrients, trophic conditions, anthropogenic input, nature of organic matter present in the habitat, substrate availability, abundance of planktons and grazing pressure influence the bacterial production, their diversity, and distribution of dominant phyla, class and genera (Eswaran & Khandeparker, 2017; Parvathi et al., 2021 and references therein).…”

“…The species present in older ballast water are tougher and thus could have the potential to proliferate in non-native environments (Ardura et al, 2021) The genus Bacillus consists of diverse species, which can utilize plant and animal debris, cellulose, hemicellulose, starch, lipids and proteins (Beleneva, 2008) and also produce antibiotics, biologically active compounds, and many of them are of ecological and biotechnological interest. The present study area, i.e., Kolkata and Kandla ports are characterized by distinct salinity, suspended particulate matter, dissolved oxygen, dissolved inorganic nutrients and chlorophyll concentration (Table 2).…”

The protein profiles of bacteria are useful markers in their identification. In this study, we examined the influence of environmental settings on the protein profiles of culturable bacteria using matrix‐assisted laser desorption ionization‐time of flight mass spectrometry (MALDI–TOF MS). We compared the protein profiles of bacteria collected from geographically distinct port environments (Kolkata, a freshwater port, and Kandla, a marine port) from India. The results indicated that bacterial species were distinctly different between the two ports, except for a few bacteria, that were common, such as Bacillus cereus, Enterobacter cloacae, Micrococcus luteus, Pseudomonas aeruginosa, P. putida, P. stutzeri, P. mosselii and Vibrio parahaemolyticus. Mass spectra of these common bacterial species, a few pathogenic among them, differed in their protein profiles and relative intensity of peaks. These variations point out that environmental settings/factors have a significant role in the protein expression and can result in differentiated virulence of pathogens. Identifying these risk factors is crucial in developing appropriate environmental port management practices.

“…The mean levels of total dissolved solids (TDS) (mg/L), total suspended solids (TSS) (mg/L) and total solids (TS) mg/L of Sample A were (100.00;40.17,and 140.17),Sample G (154.00;55.69,and 209.90),sample H (119.00;44.20,and 163.20),sample I (125.00;65.00,and 190.00),and Sample J (124.00;41.63,and 165.63), respectively, showed significant increases compared to other samples. The presence of these substances in ballast water can affect the distribution and diversity of potential pathogens in the water (Ardura et al, 2021). For example, the abundance of certain potential pathogenic genera, such as Pseudoalteromonas and Bacteroides, can vary depending on the ballast holding time (Hess-Erga et al, 2019).…”

The global menace of non-compliance with ballast water management poses a pressing environmental threat, as it facilitates the transfer of harmful organisms and sediment contaminants. This study investigates the environmental impact of ballast water discharged by ships, focusing on water quality and heavy metal concentrations. The release of ballast water, often containing elevated levels of heavy metals like mercury, lead, and cadmium, poses a significant threat to marine ecosystems. The research, involving water sample collection from ten different vessels across various countries, assesses physicochemical parameters and heavy metal concentrations. Results indicate variations in temperature, turbidity, conductivity, dissolved oxygen, and pH levels among samples. Turbidity values surpassing WHO limits suggest potential anthropogenic pollution. The study identifies significant differences in pH values, potentially influencing microbial populations. Total dissolved solids and total suspended solids values vary, affecting the distribution of potential pathogens. The results reveal varying total concentrations of heavy metals (mg/L) in the following decreasing order: SA>SE>SF>SB>SC>SD>SH>SI>SG>SJ(6.07 >4.95 > 2.07 > 1.59>0.24>1.22>0.09>0.04>0.03>0.01). The highest concentration of heavy metals is recorded for iron (SA= 5.78), zinc (mg/L) (SB = 1.36, SE = 1.30, and SF = 1.35) and lead (Pb) (SE = 2.39). The elevated iron levels in vessels from SA are potentially linked to corrosion processes. Cadmium, lead, and nickel were not detected, except for lead in the sample from SE. Copper concentrations were aligned with EU standards in the vessels. Proper ballast water management is vital for monitoring water qualities, preventing environmental spread of heavy metals, ensuring marine ecosystem health, and developing compliance strategies for ships docking in ports. Highlights Global shipping causes heavy metal pollution, affecting human and ecosystem health Physicochemical parameters variations suggest potential pollution and microbial impact Mercury, lead, and cadmium in ballast water (BW) pose threats to marine ecosystems Increased iron levels could be associated with corrosion processes Effective BW management is crucial for environmental conservation

“…The water will be discharged once the ship loads goods (Gollasch, 2018;Sayinli et al, 2021). Ballast water is also helpful in controlling the movement of ships while sailing or being hit by waves (Golash et al, 2018;Ardura et al, 2021). It is estimated that the ballast water transfers about 12 billion tons annually, equivalent to about 4 million Olympic-sized swimming pools (IMO, 2009) by the world shipping fleet and containing hundreds of species originating from coastal areas and having eutrophic water properties (Elçiçek, 2013).…”

The ballast water used as a ship's stabilizer when it is not loaded has a negative impact on health and the environment and even causes economic losses. One of them is caused by the pathogenic microbes in it. Therefore, the International Maritime Organization (IMO) enacted the Ballast Water Management (BWM) Convention to prevent the spread of pathogenic microbes that are very dangerous to health and the environment. The purpose of this study is to find out the extent of understanding of BWM Convention of the Deck and Engine Officer Class I and II in PIP Semarang. An analytical description and an overlap approach, including questionnaires, and in-depth interviews were applied to the research method. A total of 27 students from the deck and engine departments were included in the sample. According to the survey's findings, most participants don't fully comprehend the BWM contract. When being asked whether BWM was regulated, the correct answer was 0%. The right response when being asked whether Indonesia ratified the BWM was 0%. When being asked how the efficiency of BWM was 3.7% for the D-1 standard (ballast replacement) and 11.1% for the D-2 standard (ballast handling). However, 44.4% of respondents correctly identified the significance of treating ballast water, indicating that they are worried about the threat posed by this substance and that immediate action is required. The idea is to provide the student officers with knowledge via seminars, which could include training on maritime pollution or special ballast water training.
