BACKGROUND Phospholipase A1 is an enzyme that hydrolyzes phospholipids at the sn-1 position. It has potential applications across diverse fields including food, pharmaceutical, and biofuel industries. Although there has been increasing interest in the use of phospholipase A1 for degumming of plant oils during biodiesel production, production of recombinant phospholipase A1 has been hampered by ...

Wild Silkmoth cocoons are difficult or impossible to reel under conditions that work well for cocoons of the Mulberry silkmoth, Bombyx mori . Here we report evidence that this is caused by mineral reinforcement of Wild Silkmoth cocoons and that washing these minerals out allows for the reeling of commercial lengths of good quality fibers with implications for the development of the "Wild Silk" ...

Many contaminants, such as phosphatides, mucins, free fatty acids, dyes, and compounds that impact the color odor, are present in crude fats oils variable concentrations. The standard chemical refining process removes these contaminants at numerous stages, including activation, carbonization, filtration, absorption, degumming, neutralization, bleaching. While degumming is done to remove phospha...

During the raw silk degumming process, water-soluble natural protein sericin is discarded as waste material in sericulture industry of Bangladesh. In this study, various amount (as nutritional supplement) treated mulberry leaves was fed to three different silkworm groups and its effect on cocoon, pupal parameters well grainase properties silkworms evaluated. The results indicated that fecundity...

Removing sericin from the periphery of silk without damage to fibroin (SF) obtain high-molecular-weight SF is a major challenge in field SF-based biomaterials. In this study, four neutral proteases, subtilisin, trypsin, bromelain and papain, were used degum silk, degumming efficiency proteases their influence on molecular weight (MW) regenerated studied. The results indicated that all could rem...

Abstract Used cooking oil has the potential to be used as raw material for biodiesel. However, high Free Fatty Acid (FFA) content in can interfere with transesterification process. This issue will affect quality of biodiesel yields. Therefore, FFA must reduced through a pre-treatment process by adding activated carbon adsorbent from charcoal. In this study, adsorption was carried out mixing and...

Bast fibers, such as ramie, hemp, flax and kenaf, are natural fibers with high specific stiffness strength that have gained increasing attention in recent years. advantageous terms of their biodegradability abundance nature, making them promising candidates for automotive industry, structural composites, pulping textile applications etc. There is a strong desire from industry yielding cellulose...
