<div dir="ltr"><div>Dear All, </div><div><br></div><div>We received a (recent) bone collection of reptilia, part of which had been prepared using bio powder detergent (active enzymes). Accumulations of the powder are still present in some of the bones and apparently are still active, causing damage to the bones. It will be very helpful to hear from those of you who may have dealt with this problem and perhaps successfully removed or neutralized the action of the bio agent. </div><div><br></div><div>Basically I'm considering two ways of action: trying to find a way to wash out or chemically neutralize the active enzymes (somewhat tricky because apparently more than one kind of commercial bio detergent product had been used and the accumulations are pretty stubborn as far as rinsing is involved), and/or planning a specialized storage environment for specimens with such accumulations. Learning from you would be most helpful! </div><div><br></div><div>Thank you, </div><div><br></div><div>Gali </div><div><br></div><span class="gmail_signature_prefix">-- </span><br><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><font color="#000080" face="tahoma" size="2"><img width="295" height="590" style="width:57px;height:107px" src="https://docs.google.com/a/mail.huji.ac.il/uc?id=0B5B3I3QnN7dsSzNkbGlLNDNGWG8&export=download">Gali Beiner (ACR)</font></div><div><font color="#000080" face="tahoma" size="2">Conservator, Palaeontology
