Novel research has been conducted on , focusing on stems fiber (agricultural waste), for the extraction of cellulosic fiber, an area lacking prior scientific exploration. This fiber is being reported for the first time in the scientific community. Miller variety was subjected to various cultivation methods, including the application of inorganic and organic fertilizers, along with the removal of lower leaves to promote stem growth.

Genome editing is a technology to make specific changes in the DNA of a cell or an organism. It has significantly altered the landscape of life sciences, facilitating the establishment of exceedingly customized genetic modifications. Among various genome editing technologies, the CRISPR/Cas9 system, a specific endonuclease induces a double stranded DNA break and enabling modifications to the genome, has surfaced as a formidable and adaptable instrument.

Salt stress is one of the significant abiotic stress factors that exert harmful effects on plant growth and yield. In this study, five cultivars of mung bean ( L.) were treated with different concentrations of NaCl and also inoculated with a salt-tolerant bacterial strain to assess their growth and yield.

The purpose of this study was to synthesize ecofriendly nano-composite in which agricultural waste (seeds of was used to synthesize tamarind seed polysaccharides (TSP) and its composite with copper nanoparticles (Cu-NPs) for the purpose of green and clean environment as well as reduction of green-house gases. Confirmation of extracted TSP, synthesized nanocomposite was carried out using FTIR, SEM, PXRD and EDX techniques. In FTIR analysis TSP gives a strong broad peak at 3331 cm due to -OH group and in case of composite its intensity is reduced which might be due to the interactions between -OH and Cu ions.

Water scarcity poses a global threat in climate change era, and regrettably, the textile processing industry is squandering a significant volume of water during bulk production. This research focused on a sustainable water-saving approach in the printing of cotton fabric by modifying the reactive printing recipe and methodology. Three modified recipes (X, Y, Z) and one controlled recipe (C) were tested using reactive dyes.

Mitigating climate change can be achieved by opting for sustainable, plant-based materials instead of relying on hazardous chemicals that come with various side effects. Various natural plant extracts find widespread application in synthesizing insect-repellent coatings, particularly in industries such as paint manufacturing. The increasing demand for these coatings has led us to find out the effects of different plant extracts for the efficient preparation of paints with more advanced impacts and low cost.

In this research paper, a novel process was developed for reactive printing of cotton fabric, with the objective of producing a high-quality printed fabric that is sustainable, eco-friendly, and low-cost which will ultimately reduce the impact of climate change. The study incorporated substituted tamarind polysaccharide (STP) obtained from agricultural waste, trichloro-ethanoic acid (TCEA), and polyethylene glycol (PEG-400) in the reactive printing paste. Tamarind starch was extracted from the seeds having 72 % yield, and substitution was performed to use it as a thickener in the printing paste.

The study revealed enhanced production of α 1, 4 D glucan glucanohydrolase utilizing the synergistic phenomena of bacterial hetero-culture. For this purpose, 101 hetero-cultures were screened qualitatively and quantitatively. The bacterial hetero-culture showing the highest amylolytic potential was identified as Bacillus subtilis and Bacillus amyloliquefeciens by 16S rDNA sequencing technique.

Article Synopsis
  • The study examined bacterial contamination levels in ras malai samples from 14 different locations in Lahore, Pakistan, comparing both packed and unpacked varieties.
  • Results showed that packed samples had the highest bacterial count in Sample 1 at 422 × 10⁴ and the lowest in Sample 4 at 21 × 10⁴, while unpacked samples had the highest in Sample 3 at 200.3 × 10⁴ and the lowest in Sample 1 at 110 × 10⁴.
  • The findings suggest that marketed ras malai samples have higher bacterial counts than acceptable sterilization standards, potentially posing health risks, especially to children.
