The effect of UV radiation on O-7 Actinomycete in producing bioactive compounds in different growth conditions

Actinomycetes have been identified as an origin of many secondary metabolites, antibiotics and active components that impact microbial growth. Mediated mutations using UV in practice for the breeding of organisms. The objective of this study is to analyses the impact of UV radiation on the (O-7) Actinomycete isolate. This was a prospective analytical study of a several of actinomycetes. The isolates were screened for antimicrobial efficacy against multiple Gram-positive, Gram-negative bacteria, yeast, and fungi. Various factors such as UV, temperature, pH, light, agitation, fermentation durations and aeration have also been boosted for optimal antimicrobial production. The isolate (O-7) Actinomycete has been recognized as a highly bioactive producing organism. The isolate was exposed to various wavelengths, times under numerous growth conditions. It was found that 4% concentration of glucose as a carbon source is significantly optimal for the production of antibiotic for (O-7) UV exposed strain, however, concentration of 1% of lactose is significantly optimal for the production of antibiotic for (O-7) UV exposed strain. Yeast extract at a concentration of 1% was found to be the best source of nitrogen for (O-7) UV exposed, while pH 7.0 was found to be the most suitable for the same isolate. From the temperature optimization study, it was observed that (O-7) exposed strain showed good growth and maximum antibiotic production at 28 °C. The soil-isolated biological compounds (O-7) were effective against certain types of bacteria and fungi, and the research also demonstrated that exposure to UV radiation enhanced the production of these compounds.
