Bacillus licheniformis morphology

The maximum pectinase producing bacterial strain was identified as Bacillus licheniformis on the basis of morphological, physiological and biochemical characteristics. For further confirmation of identification, 16S rDNA sequence analysis was performed B. licheniformis is ubiquitous in nature, existing predominately in soil as spores. Unlike other bacilli that are typically aerobic, B. licheniformis is facultatively anaerobic, allowing for growth in additional ecological niches. The microorganism is usually saprophytic. Its production of proteases and ability to break down complex polysaccharide B. licheniformis is a rod-shaped, gram positive motile bacterium. It is spore-forming under harsh conditions and closely related to the widely studied B. subtilis. Unlike other bacilli which are predominately aerobic, B. licheniformis is a facultative anaerobe, which explains it's ability to grow in additional ecological niches and environments morphology is variable, and may give the appearance of a mixed culture. Colonies are round to irregular in shape, 2-4 mm in diameter, with margins varying from undulate to fimbriate. Color is whitish and may become brown. On agar media: colonies become opaque with dull to rough surface, hair-like outgrowts (licheniform), attached strongly to agar

B. licheniformis is a Gram positive, spore-forming, facultative anaerobic, rod-shaped bacterium. It was initially named Clostridium licheniforme by H. Weigmann and renamed Bacillus licheniformis by Frederick D. Chester. B. licheniformis displays a variety of colony morphologies, with the rough licheniform colonies giving the organism its name Bacillus species are the most common microorganisms used as probiotics in the feed industry. The current study investigated the growth and surfactin levels of Bacillus licheniformis in solid-state fermentation using different substrates and evaluated the effects of B. licheniformis -fermented products on growth performance and intestinal morphology in broilers exposed to C. perfringens

Additionally, Microgen Bacillus-ID identified 3 possible isolates with varied percentage of probability: B. subtilis, 82.7%, B. licheniformis with both 37.9% and 80.2% (Table 1). Moreover, the results showed that are positive to citrate utilization and have significant capability of fermentation of the sugars cellobiose, mannitole, mannose. Necrotic enteritis infection poses a serious threat to poultry production, and there is an urgent need for searching effective antibiotic alternatives to control it with the global ban on in-feed antibiotics. This study was conducted to investigate the effects of dietary Bacillus licheniformis replacing enramycin on the growth performance and intestinal health of subclinical necrotic enteritis. Bacillus spp. seem to be an alternative to antimicrobial growth promoters for improv-ing animals' health and performance. Within this regard, Bacillus licheniformis have the ability to sporulate, thereby making them stable during thermal treatment of feed and resistant to enzymatic digestion along the gastrointestinal tract (GIT) [16] The present study evaluated the effect of three feeding methods (dry feed, wet feed or wet feed fermented with Bacillus licheniformis) on the growth performance, intestinal histomorphometry and gene expression of the lipid metabolism- and growth-related genes of broiler chickens. A total of 360 one-day-old Cobb-500 broiler chicks were randomly allotted into three groups containing four.

THE occurrence of filamentous forms of rod shaped microorganisms is well documented, and in Escherichia coli mutant filamentous strains (lon) have been isolated and the locus of the gene mapped 1 . This gene has also been introduced into a coccal mutant of E. coli to give giant forms 2 . Filament formation can also be readily induced phenotypically by interfering with wall formation (for. Background Our laboratory has constructed a Bacillus licheniformis strain that secretes alkaline protease (AprE) with excellent enzymatic properties. B. licheniformis is generally regarded as safe and has a high industrial exoenzyme secretion capacity, but the host retains some undomesticated characteristic that increase its competitiveness and survival, such as spore-formation, which. Bacillus licheniformis can cause foodborne illness, with nausea, vomiting, diarrhoea and stomach cramps occurring 5-12 h after consumption of a variety of foods that have included ice cream, deserts, meat pies and sandwiches; counts, where made, ranged from 3 × 10 5 to 1 × 10 8 CFU g −1 of the implicated food (Salkinoja-Salonen et al.

For rod-shaped or filamentous bacteria, length is 1-10 µm and diameter is 0.25-1 .0 µm. E. coli , a bacillus of about average size is 1.1 to 1.5 µm wide by 2.0 to 6.0 µm long. Spirochaetes occasionally reach 500 µm in length and the cyanobacterium. Oscillatoria is about 7 µm in.
