So it wasn't total. inappropriate for
about 60 scientists to meet here to exchange
some of the latest results on ever\ hing from
plant nutrition, pathology, and phisioloc
of standard and novel fruit crops of the trop-
ics. kAhile banana dominated the presenta-
tions in plant nutrition, breeding and pest
management, most researchers studying
plant physiology in greenhouses around
Germany or in the fields around the world
chose citrus as their model plant. It was a
great opportunity to look beyond the citrus
industry and get some update on (mostly
German) perspective on citrus research prior
to the ISC Congress in Orlando next year.
Of particular interest to me was meet-
ing former colleagues and teachers from the
University of Bonn, which soon will be a
partner university with L'F. The school of
agriculture established a MS program that
can be used to replace or substitute course
work of any American program and is look-
ing for students to take the challenge to
study overseas. I also expect the reestab-
lished contacts with faculty from the re-
centl\ reorganized Institute for Horticulture
to result in further direct exchange and co-
operation in the near future.

CREC Scientists Study Techniques for

Citrus By-Product Processing

Trevor Gentry, CREC Graduate Student, Works on Methods
for Measuring VOC Emissions From Processing Plants


You might think of citrus
peel as something to throw
away, but the citrus industry
has found several uses for
the peel, pulp and other
waste products generated in
juice processing. F\ery
effort is made to recover as
much usable product as
possible.
At citrus juice procLs'Lain
plants, oils from the peel are
extracted for food fla\ or-
ings. The rest of the leftover
peel, pulp and other residues
are sent to a feed mill, where
much of it is converted to
cattle feed, according to Dr.

residual oils from the peel are lost as
vapor. This vapor is not hazardous, but
in Florida, the emission of compounds
into the environment is regulated by the
Department of Environmental ProiecLion
under the EPA's C'lean Air Act. Gentry's
challenge is to develop ways for juice
processing plants to monitor emissions
from feed mills, so they can ensure they
are meeting government regulations.
Most of Gentry's work has Focused on
the chemical, d-limonene, which com-
prises approximately 95'.. of the oil in the
orange peel. \While d-limonene is not
considered a hazardous air pollutant by
the EPA, it is classified as a volatile
organic compound (VOC). C rus
processing plants cannot emit more than
100 tons VOCs per year.
\hlille most plants and trees have the
capacity to s nthesize d-limonene, citrus
is unique in that it accumulates and stores
the oil in the peel. The d-limonene and
other peel oils give citrus its characteris-
tic scent.
Because d-limonene comprises most
of the VOC emissions from feed milli.

scanning electron micrographs of pollen
to depict extraterrestrial bacteria (she got
the idea from an antihistamine ad), and
photographs of sea urchin embryos
for alien organisms found in the Arctic.
For Simon, the job is fun but not
necessarily fri, ilous She takes it
seriously, and tries to make sure that
scientists on the show are portrayed in a
positive manner. Her input helps ensure


that the characters use accurate scientific
methods and tools. For example, she
makes sure that the characters use
electron microscopes to examine viruses,
as opposed to light microscopes, which
which aren't powerful enough to view
somenlhiiiig so small.
Carter once asked Simon what a
scientist would do if the, suspected ltie.
had some extraterrestial bacteria. Simon
explained that first, you would -'gro' it
up," -clrriin to the method of culturing
bacteria in nutrient media and allowing


the bacteria to divide and multiply.
Carter then asked Simon what kind of
container one would use for growing
bacteria. "An Erlenmeyer flask," she
replied. And so the episode entitled, "The
Erlenmeyer Flask." was born.
Lest one would blame Simon for all of
"The X-Files" scientific inaccuracies,
Simon is consulted only on Carter's
manuscripts, noting that there are other
writers for the show. She is writing a
book about "The Real Science Behind the
X-Files," due out in the near future.

P-Card "Bill-To" Address

[- This notice, like all P-Card
P-CARD announcements, is posted
-'M-1**" outside the Business Office.

The "Bill to:" address for Purchasing
Card transactions is:
POB 115250, Elmore Hall,
Radio Road, Room 102
Gainesville, FL 32611
This is the address Visa needs in order
to authorize your purchase. Note that
this is different than our "Ship To"
address, which is CREC.

Reason: Whenever the NationsBank
Visa authorization system sees a "Bill
to:" address different from the "Ship
to:" address, it raises concern. There-
fore, when making phone or internet
orders, you may be asked for a "Bill
to:" address. This is Visa's way of
checking for fraud. In theory, if
someone other than the cardholder was
using the P-card to try and make a


purchase, they would not likely know
the "Bill to." address.


$ OCO Threshold Raised $
We have received notification from the
State Comptroller's Office that effective
July 1. 1999, the dollar value for
operating capital outlay (OCO) has
increased from $500 to $1000 (Florida

There is a new Federal Express contract,

- If lightning struck your hard drive
tomorrow and destroyed all data on it,
could you recover, or would that be an
appropriate time to retire?
- If your data are backed up are your
backups stored next to your PC?
- How many backups do you have?
- In this session, we'll start by looking at
suggested ways to organize data for
efficient and effective backup and
(perhaps) recovery, and try to answer
some questions, such as:
What data should I back up'
Where is it located on my hard drive?
How should I back it up?
When should I back it up?
Where should I keep the backups?
How do I recover from a disaster
using my backed-up data?
How much does all this cost '
