“…Many P. mirabilis , P. vulgaris , P. penneri , P. genomospecies 4, and unidentified Proteus sp. strains isolated from the intestines of black tiger shrimp, cobia marine fish, snubnose pompano marine fish, and ornate spiny lobster in Vietnam demonstrated probiotic properties linked to bacteriocin production and their antagonistic activity towards many pathogenic bacteria [97]. …”

Proteus spp. bacteria were first described in 1885 by Gustav Hauser, who had revealed their feature of intensive swarming growth. Currently, the genus is divided into Proteus mirabilis, Proteus vulgaris, Proteus penneri, Proteus hauseri, and three unnamed genomospecies 4, 5, and 6 and consists of 80 O-antigenic serogroups. The bacteria are known to be human opportunistic pathogens, isolated from urine, wounds, and other clinical sources. It is postulated that intestines are a reservoir of these proteolytic organisms. Many wild and domestic animals may be hosts of Proteus spp. bacteria, which are commonly known to play a role of parasites or commensals. However, interesting examples of their symbiotic relationships with higher organisms have also been described. Proteus spp. bacteria present in soil or water habitats are often regarded as indicators of fecal pollution, posing a threat of poisoning when the contaminated water or seafood is consumed. The health risk may also be connected with drug-resistant strains sourcing from intestines. Positive aspects of the bacteria presence in water and soil are connected with exceptional features displayed by autochthonic Proteus spp. strains detected in these environments. These rods acquire various metabolic abilities allowing their adaptation to different environmental conditions, such as high concentrations of heavy metals or toxic substances, which may be exploited as sources of energy and nutrition by the bacteria. The Proteus spp. abilities to tolerate or utilize polluting compounds as well as promote plant growth provide a possibility of employing these microorganisms in bioremediation and environmental protection.

“…The sequences of bacterial isolates were analyzed using Basic Local Alignment Search Tool (BLAST) at www.ncbi.nlm.nih.gov to the database of 16S ribosomal RNA sequences (Bacteria and Archaea). The gene sequences were aligned with multiple alignments using Clustal W and Bioedit was used to remove the gap's region (Nguyen et al 2014).…”

Abstract. Nurhikmayani R, Daryono BS, Retnaningrum E. 2019. Isolation and molecular identification of antimicrobial-producing Lactic Acid Bacteria from chao, South Sulawesi (Indonesia) fermented fish product. Biodiversitas 20: 1063-1068. Chao is traditional fermented fish made of anchovy (Stolephorus sp.), rice, salt, and fermented naturally on controlled environment. The product comes from Pangkep Regency, South Sulawesi. Chao has the potential for the source of high-grade lactic acid bacteria isolates, especially for antimicrobial compound. Antimicrobial compound produced by lactic acid bacteria is a biopreservative compound with many advantages. The purposes of this investigation were to isolate antimicrobial-producing lactic acid bacteria from chao and to identify their isolates based on the molecular properties. Lactic acid bacteria were isolated from chao using Man Ragosa Sharpe Agar (MRSA) medium added with 0.1 % CaCO3, followed by the ability test to produce antimicrobial compound against Staphylococcus aureus FNCC 0047 as an indicator. The spectrum of crude antimicrobial as cell-free supernatant (CFS) was determined by antagonism against S. aureus FNCC 0047 and Escherichia coli FNCC 0049 on agar well diffusion test. Selected isolates of antimicrobial-producing lactic acid bacteria molecularly identified from 16S rRNA marker using primer 27F and 1492R. We obtained four isolates of lactic acid bacteria that showed the antimicrobial activity. This crude antimicrobial compound could inhibit both gram-positive Staphylococcus aureus FNCC0047 and gram-negative bacteria Escherichia coli FNCC0049. The highest crude antimicrobial activity of isolates was observed on IB1C strain. The results of molecular characterization suggested that the IB1C and IB3B strain were identified as Lactobacillus plantarum, whereas IB3E and IB3F were identified as Pediococcus pentosaceus.

“…By contrast, most of the PCL+ bacterial isolates appear capable of coexisting on the tail fans. As the bacteria which are inhibited by other bacteria are less likely to survive in an open environment, such as on a lobster tail fan, those bacteria capable of coexisting or inhibiting others are more likely to be persistent and capable of colonizing hosts (Nguyen et al., ; Sant'ana et al., ; Zeng et al., ). The relevant result suggests that a number of PCL+ bacterial isolates may be collectively associated with TFN.…”

“…Antimicrobial activities among bacteria are common (Nguyen, Pham, Nguyen, Nguyen, & Hoj, ; Sant'ana, Barbosa, Destro, Landgraf, & Franco, ; Smaoui et al., ; Zeng et al., ), but unreported in bacteria associated with classical shell disease, including TFN. Among the bacteria on the tail fan of lobsters, the bacteria associated with TFN may be advantaged by the ability to inhibit other bacteria.…”

Tail fan necrosis (TFN) is a common condition found in commercially exploited spiny lobsters that greatly diminishes their commercial value. Bacteria possessing proteolytic, chitinolytic and lipolytic capabilities were associated with TFN in spiny lobsters, Jasus edwardsii. In this study, 69 bacterial isolates exhibiting all the three enzymatic capabilities from the haemolymph and tail fans of J. edwardsii with and without TFN were further characterized and compared, including morphology, biofilm formation, antimicrobial activity, antimicrobial resistance, and production of siderophores, melanin and ammonia. The genomic patterns of the most common Vibrio crassostreae isolates were also compared between TFN-affected and unaffected lobsters. Biofilm formation was stronger in bacterial isolates from both haemolymph and tail fans of TFN-affected lobsters compared to those from the unaffected lobsters, while melanin production and siderophore production were stronger in the isolates from tail fans of lobsters with TFN. By contrast, the other characteristics of isolates were similar in lobsters with and without TFN. The Vib. crassostreae isolates from the affected lobsters had similar genomic patterns. Overall, the results indicate that in addition to proteolytic, chitinolytic and lipolytic activities, the bacteria associated with TFN commonly have enhanced activity of important virulence factors, including biofilm formation, melanin production and siderophore production.
