“…Bacillus is distinguished from other endospore-forming bacteria by being a strict or facultative aerobe, rod-shaped, and catalase positive. Korzybski et al (1978) and Zimmerman et al (1987) reported that most Bacilli produce antibiotics such as difficidin, oxydifficidin, bacitracin, polymyxin, subtilin, mycobacillin, bacillin, gramicidin, or bacillomycin B and are antagonistic to pathogenic bacteria in both in vivo and in vitro conditions confirming the present results for B.…”

The present studies were conducted to isolate, select, identify and characterize gut bacteria as antimicrobial and growth promoting agent for the feed of economically important fish Cirrhinusmrigala. Intestinal microflora were isolated, counted, and identified, and their in vitro antibacterial properties were determined. The results have revealed that occurrence of gram negative rods was around 75% and of gram positive rods was 25%. Amongst the isolates gram positive were maintained in nutrient agar slants at 4°C. Of these, eight strains were replica-plated on agar seeded with Aeromonashydrophila and only one strain CM2 (Cirrhinus mrigala 2) exhibited antibacterial properties in vitro showing inhibition against fish pathogen by well diffusion assay. This isolated strain was identified as Bacillus cereus. This bacterium was mass cultured and incorporated in the pelleted diet (40% protein and 18 kJ g-1 gross energy) of C. mrigala to investigate its effect on growth performance, digestibility, nutrient retention and activities of digestive enzymes. The results of feeding trial revealed significantly (P<0.05) high growth performance in terms of specific growth rate, growth percent gain in body weight (272.4±1.5), high apparent protein digestibility ((79.9±0.30)%) and low food conversion ratioin the group of fishes fed on diet containing B. cereus in comparison to the fishes fed on diet without probiotics. The carcass composition also revealed high accumulation of proteins ((15.28±0.15) g 100 g-1) in fishes fed on diet containing probiotics. Intestinal enzyme activities of protease, amylase and cellulase were also significantly (P<0.05) high in the group of fishes fed on diet supplemented with probiotic indicating the extracellular enzyme production by B. cereus. These results indicate that probiotic stimulate the digestion through the supply of digestive enzyme and certain essential nutrients to animals. Also significantly (P<0.05) low excretion of metabolites, i.e., ammonia excretion and phosphate production (mg kg-1 BW d-1) was observed in the fishes fed with probiotic based diets. Thus, B. cereus appears to be a promising candidate for ptobiotic applications which can enhance growth performance and nutrient retention in C. mrigala.

“…Gramnegative bacteria count in the nontreated group was significantly higher than that in the treated group. Hence, B. subtilis has been shown to produce a wide variety of antibacterial and antifungal compounds in culture media (Alexander 1977;Katz & Demain 1977;Korzybski et al 1978). It produces novel antibiotics such as difficidin and oxydifficidin that have activity against a wide spectrum of aerobic and nonaerobic bacteria (Zimmerman et al 1987) as well as more common antibiotics such as bacitracin, bacillin and bacillomycin B (Parry et al 1983).…”

A feeding experiment was conducted to investigate the effect of Bacillus subtilis bacterium, on larval growth and development rate of Macrobrachium rosenbergii (de Man) during February 28 to April 8, 2005 in University Putra Malaysia hatchery. Newly hatched larvae of M. rosenbergii were reared with two dietary treatments consisting of newly hatched Artemia salina nauplii with B. subtilis (108 cells ml−1), and newly hatched A. salina nauplii without B. subtilis carried out in triplicate in 60‐L aquarium (50 L−1). After trial, the larvae that fed B. subtilis‐treated Artemia naupli were found to have higher survival and a faster rate of metamorphosis than larvae that were fed with nontreated Artemia naupli. There were significant differences between B. subtilis‐treated Artemia naupli and nontreated Artemia diet in larval growth and development rate of metamorphosis (P < 0.05). Larval survival after 40 days was significantly greater (P < 0.05) in the B. subtilis‐treated groups (55.3 ± 1.02) compared with the nontreated groups (36.2 ± 5.02%).

Most Bacilli produce antibiotics such as difficidin, oxydifficidin, bacitracin, polymyxin, subtilin, mycobacillin, bacillin, gramicidin, or bacillomycin B and are antagonistic to pathogenic bacteria in both in vivo and in vitro conditions (Korzybski et al, 1978;Zimmerman et al, 1987). Bacilli are not associated with aquatic organism pathology and are widely accepted and used as probionts (Moriarty, 1998).…”

As from January 2010 The Israeli Journal of Aquaculture-Bamidgeh (IJA) will be published exclusively as an on-line Open Access (OA) quarterly accessible by all AquacultureHub (http://www.aquaculturehub.org) members and registered individuals and institutions. Please visit our website (http://siamb.org.il) for free registration form, further information and instructions. This transformation from a subscription printed version to an on-line OA journal, aims at supporting the concept that scientific peer-reviewed publications should be made available to all, including those with limited resources. The OA IJA does not enforce author or subscription fees and will endeavor to obtain alternative sources of income to support this policy for as long as possible.
