Abstract Background Macrobrachium amazonicum is a freshwater prawn widely distributed in South America that undergoing speciation, so the denomination “ M. complex” used for it. The mitochondrial cytochrome c oxidase subunit I (COI) gene has been to elucidate this but heteroplasmies and pseudogenes have recorded, making separation difficult. Obtaining genes from cDNA (RNA) rather than genomic DNA an effective tool mitigate those two types of occurrences. aim study was assemble silico (mtDNA)...
Over recent years, Macrobrachium amazonicum has become a popular species for shrimp farming due to their fast growth, high survival rates, and marketability. Several studies have focused on the development of new technology culture this species, but many aspects nutrition physiology remain unknown. Thus, goal present study was obtain transcripts putative genes encoding digestive enzymes, based library cDNA from hepatopancreas M. amazonicum, sequenced in Ion TorrentTM platform. We identified...
The acid phosphatase (ACP) enzyme is responsible for the hydrolysis of phosphate monoesters under acidic conditions, being widely found in microorganisms, animals and plants. In crustaceans, ACP plays a key role defense mechanism distinct species. Furthermore, expression sensitive to pollution, particularly related stress response by exposure heavy metals organophosphate pesticides. However, most studies crustaceans refer biochemical properties but little known about its structural...
is an opportunistic and omnivorous species that primarily feeds on plant material. Recent studies have shown Endo-β-1,4-glucanase Endo-β-1,4-mannanase are expressed in the transcriptome of adult specimens, while juveniles capable digesting nutrients from purified cellulose their diet. In organisms degrade raw material, laccase plays a key role oxidizing phenolic compounds found lignin, leading to its depolymerization increasing access hemicellulose microfibrils.
The present study aimed to identify and characterize cellulase from the functional genome in hepatopancreas of Amazon river prawn (Macrobrachium amazonicum). Growth trials with post-larvae M. amazonicum validated endogenous expression cellulases based on analysis gene via RT-PCR evaluated effects cellulose-rich diet growth performance body composition prawn. endo-β-1,4-glucanase was identified as a part whose entire coding region corresponded 580 amino acids (aa), molecular mass 63.6 kDa...
In this study, we evaluated the utilization of two probiotics incorporated into water and in diet a larval culture system Amazon River prawn. Autochthonous probiotic bacteria from gut wild juveniles M. amazonicum commercial were tested following parameters analyzed: survival, productivity, fresh weight, length, condition index (LCI) stage (LSI). The colonization gastrointestinal tract by took place when they diet, while proved to be unsuccessful. use lactic acid had no significant effects...
