The antibiofilm potential of a heteropolysaccharide produced and characterized from the isolated marine bacterium BPM30.

Biofilms are the significant causes of 80% of chronic infections in the oral cavity, urinary tract, biliary tube, lungs, gastrointestinal tract, and so on to the general public. Treatment of pathogenic biofilm using bacterial exopolysaccharides (EPS) is an effective and promising strategy. In the present work, a marine bacterium was isolated, studied for exopolysaccharide production, and tested for its antibiofilm activity.

Maximizing the direct recovery and stabilization of cellulolytic enzymes from Trichoderma harzanium BPGF1 fermented broth using carboxymethyl inulin nanoparticles.

The carboxymethylated inulin (CMI) nanoparticles prepared by the salt out method was demonstrated to harvest cellulolytic enzymes (Ez) directly from the clarified fermented broth of Trichoderma harzanium BPGF1. The formation of CMI nanoparticles and entrapment of Ez in CMI was confirmed by scanning electron microscopy and Fourier transform infrared spectroscopy, respectively. A factorial design was developed to maximize enzymes recovery directly from the fermented broth.

Isolation and characterization of cellulose nanocrystals from jackfruit peel.

In the present work, sustainable nanomaterials, cellulose, and spherical cellulose nanocrystals (SCNCs) were isolated from the non-edible parts of jackfruit (Artocarpus heterophyllus). Of the three different methods tested, sodium chlorite treatment produced the highest yield of cellulose, 20.08 ± 0.
