Among the proteases tested, two fungal and two actinomycete proteases were promising, which showed weight loss similar to conventional method (19.58% to 21.78%). Conidiobolus brefeldianus and BOA-2 proteases were best enzymes, which showed weight loss similar to conventional method with low enzyme concentrations and in shorter time. No significant differences were found in tensile strength or elongation at break by enzymatic degumming indicating that there was no damage to the fiber. Scanning electron micrographs showed the sericin deposits were removed and the fibers were separated.</p>10aAlkaline Protease10abivoltine10adegumming10amicrobial10aSilk10aweight loss1 aMore, Shivaji, V.1 aKhandelwal, Harish, B.1 aJoseph, M., A.1 aLaxman, Ryali, Seeta  uhttps://library.ncl.res.in/content/enzymatic-degumming-silk-microbial-proteases-0
