Chitosan with pendant ()-5-((4-acetylphenyl)diazenyl)-6-aminouracil groups as synergetic antimicrobial agents.

Conventional antimicrobial agents are losing the war against drug resistance day-by-day. Chitosan biopolymer is one of the alternative materials that lends itself well to this application by fine-tuning its bioactivity using different pendant groups. Herein, we report the synthesis of novel chitosan with pendant ()-5-((4-acetylphenyl)diazenyl)-6-aminouracil (APAU) groups by forming Schiff base linkages between chitosan and the pendant groups.

Characterization of α-D-glucan produced by a probiont Enterococcus hirae KX577639 from feces of south Indian Irula tribals.

Exopolysaccharide (EPS) producing probiotic strain Enterococcus hirae KX577639 were isolated from the feces of South Indian Irula tribes. EPS yield was 18.57 g/L (dry weight) at 48 h in 2% sucrose supplemented MRS medium.

Health benefits of finger millet (Eleusine coracana L.) polyphenols and dietary fiber: a review.

The growing public awareness of nutrition and health care research substantiates the potential of phytochemicals such as polyphenols and dietary fiber on their health beneficial properties. Hence, there is in need to identify newer sources of neutraceuticals and other natural and nutritional materials with the desirable functional characteristics. Finger millet (Eleusine coracana), one of the minor cereals, is known for several health benefits and some of the health benefits are attributed to its polyphenol and dietary fiber contents.

Screening for probiotic properties of strains isolated from feces of various human groups.

The present study searched for potential probiotic strains from various human fecal samples. A total of 67 aerobic and 38 anaerobic strains were isolated from 5 different categories of human feces. Systematic procedures were used to evaluate the probiotic properties of the isolated strains.

Interaction studies of resistomycin from Streptomyces aurantiacus AAA5 with calf thymus DNA and bovine serum albumin.

Resistomycin, a secondary metabolite produced by Streptomyces aurantiacus AAA5. The binding interaction of resistomycin with calf thymus DNA (CT DNA) and bovine serum albumin (BSA) was investigated by spectrophotometry, spectrofluorimetry, circular dichroism (CD) and synchronous fluorescence techniques under physiological conditions in vitro. Absorption spectral studies along with the fluorescence competition with ethidium bromide measurements and circular dichroism clearly suggest that the resistomycin bind with CT DNA relatively strong via groove binding.
