Probiotic Paenibacillus polymyxa HGA4C and Bacillus licheniformis HGA8B combination improved growth performance, enzymatic profile, gene expression and disease resistance in Oreochromisniloticus.

Bacterial consortium containing two bacterial strains such as Paenibacillus polymyxa HGA4C and Bacillus licheniformis HGA8B incorporated in the diet of Oreochromis niloticus at a concentration of 1 × 10 CFU g (PB1) and 1 × 10 CFU g (PB2) revealed the probiotic potentials of the bacterial combination. The probiotic feed enhanced the growth performance, digestive enzymes, and antioxidant enzymes in the liver and intestine. Probiotic mediated growth enhancement was further substantiated by the up-regulation of genes such as GHR-1, GHR-2, IGF-1, and IGF-2 and the up-regulation of immune-related genes viz.

Catechin rich butanol fraction extracted from Acacia catechu L. (a thirst quencher) exhibits immunostimulatory potential.

Acacia catechu L., (Fabaceae) named as "catechu" is a plant, the decoction of heartwood of which is daily consumed as thirst quencher by a good percentage of the population in South India. The plant is mainly distributed in India and other Asian countries.

Antagonism Against Fish Pathogens by Cellular Components/Preparations of Bacillus coagulans (MTCC-9872) and It's In Vitro Probiotic Characterisation.

Bacterial fish pathogens are pervasive in aquaculture. Control of bacterial fish pathogen is a difficult task among aquaculture practitioners. A large number of antibiotics are used for the control of prevalent bacterial pathogens in aquaculture.

Efficient visible light induced synthesis of silver nanoparticles by Penicillium polonicum ARA 10 isolated from Chetomorpha antennina and its antibacterial efficacy against Salmonella enterica serovar Typhimurium.

The green synthesis of silver nanoparticles (AgNPs) using biological systems such as fungi has evolved to become an important area of nanobiotechnology. Herein, we report for the first time the light-induced extracellular synthesis of silver nanoparticles using algicolous endophytic fungus Penicillium polonicum ARA 10, isolated from the marine green alga Chetomorpha antennina. Parametric optimization, including the concentration of AgNO, fungal biomass, ratio of cell filtrate and AgNO, pH, reaction time and presence of light, was done for rapid AgNPs production.

Green synthesized silver nanoparticles by marine endophytic fungus Penicillium polonicum and its antibacterial efficacy against biofilm forming, multidrug-resistant Acinetobacter baumanii.

Acinetobacter baumanii, a gram-negative, non-motile, encapsulated coccobacillus which causes infections worldwide. The objective of this study was to find a fungal strain that could be utilized to biosynthesize antibacterial silver nanoparticles (AgNPs) against Acinetobacter baumanii. The present investigation explains rapid and extracellular biosynthesis of silver nanoparticles by the algicolous endophytic fungus, Penicillium polonicum, isolated from the marine green alga Chetomorpha antennina.

Antibacterial activity and probiotic characterization of autochthonous Paenibacillus polymyxa isolated from Anabas testudineus (Bloch, 1792).

Microbial fish pathogens are prevalent in aquaculture. Control of bacterial fish pathogens is important and bio control of pathogenic bacteria is a novel field of study. The aim of this study was to evaluate the antagonistic activity of bacteria isolated from Anabas testudineus against potent fish pathogens.

Antibacterial activity of autochthonous bacteria isolated from Anabas testudineus (Bloch, 1792) and it's in vitro probiotic characterization.

Antimicrobial potentials of bacteria isolated from Anabas testudineus have been evaluated through in vitro antagonistic activity against potent fish pathogens. The cellular components and filtered culture medium were effective against six fish pathogens. Altogether 110 strains were isolated from the fish gut, out of which 10 strains were selected through well diffusion method.
