“…Benzene acetic acid was one of those compounds found. A previous study has reported that benzene acetic acid exhibited antifungal and antibacterial properties (Tayade and Jadhao, 2012, Arasu et al, 2017, Arasu et al, 2019). Therefore, further chemical analyses will be conducted on crude extract of Al-Dhabi-2 to determine the compound/compounds responsible for the antimicrobial activity.…”

Filamentous bacterial belonged to Streptomyces species were novel drug source for medical and industrial applications. However, the detailed identification of Streptomyces species from Saudi Arabian extreme environment for the identification novel drug source for medical and industrial applications were rarely studied. The Streptomyces strain Al-Dhabi-2 obtained from the thermophilic region kingdom of Saudi Arabia, exhibited antimicrobial potentials against the pathogenic microorganism were characterized. Biochemical and phylogenetic analysis confirmed that the strain was closely associated to the Streptomyces species. The chromatogram of GC-MS analysis of this ethyl acetate extract (EA) had diverse of chemical compounds namely benzene acetic acid (7.81%), acetic acid, methoxy-, 2-phenylethyl ester (6.01%) were the major compounds. EA of Al-Dhabi-2 showed inhibition zone ranged from 14 to 25 mm at 5 mg/well concentration against the tested microbial pathogens. Results revealed that the significant MIC values were observed against B. cereus, and E. faecalis by (less than 39 μg/ml) and against S. agalactiae with (78 μg/ml). Minimum inhibitory concentrations (MIC) for fungi: were also reported against Cryptococcus neoformans and Trichophyton mentagrophytes by (156 μg/ml), whilst Candida albicans and Aspergillus niger by (312 μg/ml). Results of this study showed that thermophilic actinobacteria could be promise source in the context of searching for unique antimicrobial agents with novel properties.

Nowadays, green synthesis methods have gained growing attention in nanotechnology owning to their versatile features including high efficiency, cost-effectiveness, and eco-friendliness. Here, the aqueous extract of Chlorophytum comosum leaf was applied for the preparation of iron nanoparticles (INPs) to obtain spherical and amorphous INPs with a particle size below 100 nm as confirmed by TEM. The synthesized INPs managed to eliminate methyl orange (MO) from the aqueous solution. The concentration of MO can be easily checked via ultraviolet-visible (UV-Vis) spectroscopy throughout the usage of INPs at the presence of H 2 O 2 . The synthesized INPs exhibited MO degradation efficiency of 77% after 6 h. Furthermore, the synthesized INPs exhibited antibacterial activity against both Gram-negative and Gram-positive bacteria. The prepared INPs have an impressive effect on Staphylococcus aureus at concentrations below 6 μg/ml. Overall, the synthesized INPs could considerably contribute to our combat against organic dyes and bacteria.

“…Microbial lipases have very broad substrate specificity and high stability toward various organic solvents (Elibol and Ozer, 2000). Microbial synthesis of enzymes has influenced by various factors such as, pH, temperature carbon source, nitrogen source, incubation time and type of fermentation (Palaniyappan et al, 2009, Arasu et al, 2019a). Among these factors, nitrogen, carbon sources and their concentrations have been of potent interest to industries for the use of low cost media.…”

In this study, Streptomyces sp. Al-Dhabi-49 was isolated from the soil sample of Saudi Arabian environment for the simultaneous production of lipase and protease in submerged fermentation. The process parameters were optimized to enhance enzymes production. The production of protease and lipase was found to be maximum after 5 days of incubation (139.2 ± 2.1 U/ml, 253 ± 4.4 U/ml). Proteolytic enzyme increases with the increase in pH up to 9.0 (147.2 ± 3.6 U/ml) and enzyme production depleted significantly at higher pH values. In the case of lipase, production was maximum in the culture medium containing pH 8.0 (166 ± 1.3 U/ml). The maximum production of protease was observed at 40 °C (174 ± 12.1 U/ml) by Streptomyces sp. Lipase activity was found to be optimum at the range of temperatures (30–50 °C) and maximum production was achieved at 35 °C (168 ± 7.8 U/ml). Among the evaluated carbon sources, maltose significantly influenced on protease production (218 ± 12.8 U/ml). Lipase production was maximum when Streptomyces sp. was cultured in the presence of glucose (162 ± 10.8U/ml). Among various concentrations of peptone, 1.0% (w/v) significantly enhanced protease production. The lipase production was very high in the culture medium containing malt extract as nitrogen source (86 ± 10.2 U/ml). Protease production was maximum in the presence of Ca2+ as ionic source (212 ± 3.8 U/ml) and lipase production was enhanced by the addition of Mg2+ with the fermentation medium (163.7 ± 6.2 U/ml).
