Role of microorganisms in biodegradation of food additive Azo dyes: A review

Food additives Azo dyes are synthetic compounds added to foods to impart color and improve their properties. Some azo dyes have been banned as food additives due to toxic, mutagenic, and carcinogenic side effects. Long exposure to foods containing azo dye leads to chronic toxicity. Some microorganisms are capable to degrade these dyes and convert them to aromatic amines. In human body, microbiota can play a vital role...

An investigation of meristem culture in Anchote [Coccinia abyssinica (Lam.) Cong.] under the influence of plant growth regulators and media strength

Considering the potential benefit of meristem culture in the mass production of quality propagation materials, an experiment was conducted to investigate meristem culture in KUWE (G1) and 223098 (G2) genotypes of anchote. Concentration levels of 6-benzylamimopurine (BAP) with and without gibberellic acid (GA3) and naphthalene acetic acid (NAA) for shoot induction while BAP and kinetin (Kn) for shoot multiplication were...

Effects of inoculation with some native arbuscular mycorrhizal fungi on tomato (Solanum lycopersicum L.) growth

In Burkina Faso, tomato (Solanum lycopersicum L.) sector plays a very important socio-economic role. However, its production is confronted by many constraints, among which is the soil poverty in mineral elements such as nitrogen and available phosphorus resulting in an increase in the area of land that is sown for this crop and an increase in the use of chemical inputs. In addition, chemical inputs have shown their...

Development of starter cultures carrier for the production of high quality soumbala, a food condiment based on Parkia biglobosa seeds

In this study, three Bacillus subtilis (B7, B9 and B3) and one Bacillus amyloliquefaciens (I8) strains previously selected as potential starter cultures were cultivated on boiled dehulled African locust bean seeds to produce ready to use ferments. These ferments were then used to produce soumbala. The microbial load changes during ferments production were evaluated. Biochemical and microbiological characteristics of the...

Isolation and molecular characteristics of extended spectrum beta-lactamase-producing uropathogenic Escherichia coli isolated from hospital attendees in Ebonyi State, Abakaliki

This present study was designed to determine the occurrence frequency of blaCTX-M and blaTEM genes in extended-spectrum beta-lactamase (ESBL)-producing uropathogenic Escherichia coli, and their antibiotic resistance patterns among hospital attendees in Abakaliki, Nigeria. Out of the 73 uropathogenic E.coli isolates analyzed, 52 were identified to be ESBL producers using double disk synergy technique. The frequency of...
