“…As for amylase activity B. mojavensis J7 was positive while B. pumilus B16 was negative. B. pumilus B16 and B. mojavensis J7 had the production capacity of extracellular hydrolytic enzymes, which made them potential probiotic candidates for the enhancement of digestion and nutrient uptake by the host (Nimrat et al 2011). Members of Bacillus, compared with other species of probiotics, have achieved considerable success by the use of endospore-forming agents (Hong et al 2005), the screened B. pumilus B16 and B. mojavensis J7 in this study provided new probiotic candidates.…”

Acute gastroenteritis caused by pathogenic Vibrio parahaemolyticus is one of the major factors affecting the development of aquaculture and the safety of seafood. Using the antagonism of probiotics against pathogens is an alternative strategy to antibiotics and a common trend to control food-borne pathogenic bacteria. In this study, a total of 249 isolates were isolated from four types of seafood (Litopenaeus vannamei, Oratosquilla oratoria, Mactra veneriformis and Portunus trituberculatus) and coastal sediment from Liaodong Bay in the Bohai Sea, China with five different separation agars. The most isolates came from the sample of coastal sediment and on agar of 2216E, which accounted for 36.14 and 54.62 % respectively. Twenty-four among 249 isolates displayed direct antimicrobial activity to V. parahaemolyticus with spot inoculation. Sixteen active isolates were selected for extracellular antimicrobial activity using the Oxford cup method. Only strains of B16 and J7 showed extracellular antimicrobial activity and were identified as Bacillus pumilus and Bacillus mojavensis respectively based on the physiological identification and 16S rRNA sequence analysis. Both of the strains B16 and J7 exhibited extracellular hydrolytic enzyme activity and antagonism against more than one indicator bacteria in vitro, which indicates that the two strains have broad potential application as suitable probiotic candidates in aquaculture while B. mojavensis was first reported to inhibit pathogenic Vibrio spp. in vitro. There is no particular trait as to antagonism of B. pumilus B16 or B. mojavensis J7 to Gram-positive or Gram-negative indicator bacteria.

“…Selain itu, penelitian lain menyebutkan bahwa Bacillus merupakan salah satu kelompok bakteri yang telah dimanfaatkan sebagai bakteri probiotik di bidang akuakultur. Beberapa penelitian telah menunjukkan bahwa bakteri kelompok Bacillus sebagai probiotik secara signifikan dapat meningkatkan kualitas air (Nimrat et al, 2011;Nimrat et al, 2012), rasio konversi pakan (FCR), laju pertumbuhan (SGR), rasio konversi protein (PER) (Merrifield et al, 2010), peningkatan respons imun dan resistensi terhadap penyakit (Li et al, 2009).…”

This study aimed to analyze the genetic diversity of bacteria associated in bioflocs using 16S-rRNA polymerase chain reaction (PCR) with ARDRA technique. A total of 38 dominant bacterial isolates was obtained from bioflocs samples and of these isolates, 16S-rRNA gene was then isolated and amplified using PCR. The 16S-rRNA gene of the isolates was then cut using HaeIII (5'-GG↓CC) and HhaI (5'-GCG↓C) restriction enzymes resulting an ARDRA pattern which was further used as the binary data for the construction of phylogenetics tree that was used to estimate the group of bacteria. The result with HaeIII cut restriction enzyme from biofloc-associated bacteria gave 11 ARDRA patterns, while with the restriction enzyme HhaI gave eight ARDRA patterns. Phylogenetics of bacterial populations from biofloc-based cultivation system water consisted of at least 13 different bacterial species. Result of sequencing from two gene sample 16S-rRNA were identified as Microbacterium foliorumand and Pseudomonas putida.

“…A biorremediação é uma opção para o desenvolvimento da aquicultura sustentável, uma vez que a utilização dos antibióticos e outros produtos químicos deve ser limitada para manter a qualidade da água e das condições ambientais em viveiros de cultivo de camarão (Jha, 2011). Desta forma, o desenvolvimento de probióticos para a substituição de antibióticos é um dos fatores-chave para a gestão na aquicultura sustentável (Nimrat et al, 2011).…”

RESUMOA carcinicultura é uma atividade importante da agroindústria em várias partes do mundo e que sofre perdas significativas devido à ocorrência de doenças. Dentre os agentes patogênicos, as bactérias do gênero Vibrio têm destaque pelos elevados índices de mortalidade registrados. O emprego de antibióticos é a opção mais frequente no combate a essas enfermidades, entretanto seu uso não criterioso aumenta a pressão seletiva sobre estirpes bacterianas resistentes no ambiente aquático, o que resulta em risco ambiental e para a saúde de animais e humanos. Novas tecnologias vêm sendo desenvolvidas no combate de doenças nos ambientes de cultivo de organismos aquáticos prevenindo assim, perdas econômicas. Esforços vêm sendo aplicados para a compreensão dos processos infecciosos e rotas de invasão das estirpes de Vibrio em camarões cultivados a fim de estabelecer melhores técnicas de combate aos patógenos. Procedimentos de biossegurança nos cultivos devem ser desenvolvidos integrando conceitos de saúde, nutrição, genética e qualidade ambiental para um efetivo controle e combate de enfermidades. Este trabalho de revisão tem como objetivo traçar um perfil sobre esse novo panorama que se desenha na atividade da carcinicultura e as alternativas no combate às vibrioses.Palavras-chave: biossegurança, carcinicultura, vibriose, patógeno. ABSTRACTShrimp farming, an important agribusiness activity worldwide, experiences significant losses due to diseases.
