Gmitter Selected
to Lead the Inter-
national Citrus Ge-
nome Consortium
By Kathy Snyder

D r. Fred G. Gmitter, Jr.,
Professor of Citrus
Genetics and Breeding, was
recently selected as Leader of
the International Citrus Ge-
nome Consortium by the group
that met on January 14, 2006
at the International Plant and
Animal Genome Conference
in San Diego, CA. The Inter-
national Citrus Genome Con-
sortium was first established in
2003 at a meeting in Valencia,
Spain. The Consortium con-
sists of a worldwide group of
scientists, researchers, gradu-


Over-the-Road Food
Tanker Cleaning
Validation Unit
By Kathy Snyder

The Over-the-Road Food
Tanker Cleaning Valida-
tion Unit is quite a mouthful
when trying to describe the in-
genuity and diligent efforts of
Paul Winnicuk, Gwen Lundy,
and Tracy Meadows. This team
has built the first mock-up of its
kind of a food transport tanker


ate students, and citrus indus-
try leaders representing several
constituent countries and re-
search groups. Their collective
goal is the large-scale realiza-
tion of the complete underlying
genome sequence and genetic
structure of Citrus in the near


future, through coor-
dinated international
collaboration. In
order to retain the
essential character-
istics of varieties and
to achieve significant
improvements in
critical traits of citrus,
the application of ge-
netic improvement
techniques other than
traditional breeding
through sexual hy-
bridization and selec-
tion is required. The
Consortium members
have been meeting annually at the
International Plant and Animal
Genome Conference. More infor-
mation is available on their web-
site http://int-citrusgenomics.org.

and the unit is approximately 25
feet long and 6 ft x 6 ft. It features
one clear side and front end. Tak-
ing into account for the exterior
shell and insulation, the interior
of the unit is 22 feet. The mock-
up is a few feet longer than half
the trailer size to accommodate the
top entry hatch which is off center.
Construction of the mock-up began
in December 2005 and continued
into January 2006, approximately 6
weeks overall according to Lundy.
Winnicuk, the project leader, is
continuing the research started with
Dr. Mickey Parish in 2004 and con-
tinuing with Dr. Ren6e Goodrich on
tanker decontamination and clean-
ing. Sprayer manufacturers have
sent their equipment to be tested.
In a continuing effort to help the
industry, Winnicuk travels with
the unit to various tanker wash fa-
cilities throughout the state. Their
equipment and methods for clean-
ing and sanitizing the interior of
the tankers are tested in the unit to
insure HACCP regulations are be-
ing met with the transport of juice.

Currently, tanker manufacturers,
sprayer manufacturers, tanker wash
facilities, systems cleaning compa-
nies, and the University of Florida
are working together to improve
juice transport quality and purity.
In addition, many of the chemical
cleaning companies have contacted
Winnicuk expressing an interest in
the research.
Winnicuk explained how spray-
ers are lowered in through the top
hatch and run for a full cycle. As
part of the experiments, dye was
added to bacteria samples and
spread through the mock-up tanker.
Sprayer units were then used for a
full cleaning cycle. Some results
were not so favorable.
The industry uses several types of
cleaning cycles and those used most
often by the citrus industry are ei-
ther Type 2 or 4. The average tank
cleaning for Type 2 is a 45 minute
cycle using 22 gallons per minute for
a total of 990 gallons of un-recycled
water. For the Type 4 cleaning cycle
it is 75 minutes using 22 gallons per
minute for a total of 1650 gallons of
un-recycled water. On average the
tanker wash facilities use 475,000







gallons of water per month, and not
only pay for the water to come into
their facility but also for the waste
water flushed out.
There is currently a sprayer avail-
able that can reach all sides of the
interior but it uses 105 gallons per
minute which would result in 2.3
million gallons of water per month,
four times what is being used now.
This is unacceptable by the industry.
Sprayer manufacturers and tanker
wash facilities are very interested
with the testing of low volume yet
high pressure sprayers that would be
able to accomplish the same clean-
ing range.
This problem has not seemed to
have as much of an affect to the
dairy industry as dairy products are
re-pasteurized after arriving at the
processing/packing facilities; juice
products are not. "Re-pasteuriza-
tion will affect the flavor, color, and
vitamin content of citrus juice in
particular," stated Winnicuk.
At this time there are no facili-
ties set up to recycle the water used
by the tanker wash and sanitation
facilities. Winnicuk stated that as
research continues, recycling would
become the next phase.

Precision Ag Seminar Outcome
By Christen Taylor


Japanese visitors Naoshi Kondo and Kentaro Nishiwaki
conducted a brief informative seminar regarding new
technologies in grading and sorting systems for fruits and
vegetables on Dec. 15, 2005. Kondo is the director of SI Sei-
ko Co., Ltd. in Japan and Nishiwaki is a researcher for the
National Agriculture and Bio-oriented Research Organiza-
tion in Japan. Several pertinent topics were discussed dur-
ing the seminar that gave the crowd motivation to broaden
their views of the several precision agricultural technologies
created in Japan.
Some of the topics discussed included: The five impor-
tant parameters of soil sensoring, robotics in agriculture and grading robotic sys-
tems. The new invention of a handheld device that measures the sugar content
of fruit and costs approximately $20,000 $30,000 was discussed as well. The
device has a + 1 degree dif-
ference and measurements
for detecting the acidity are
not that accurate. Further
research to improve this
product is underway.
The seminar was spon-
sored by the Precision Agri-
cultural Team at the CREC.
If you have any questions
or comments regarding the
seminar contact Dr. Reza
Ehsani for additional infor-
mation at ehsani(Bufl.edu.

And the Changes Just Keep on Comin'
By Kathy Snyder



S' s the updating and upgrading of the Center continue,
-the most recent changes have been the demolition
L of the older greenhouses between the Administration Build-
ing 7124 and the Lab Areas and Photo Lab located in 7110.
New greenhouses were constructed north of the main build-
Sing replacing the old.






In addition to the
greenhouse demolition, .
the construction area
for the new building be- .:... .. ..
tween 7124 and 7130 has
been secured with fenc-
ing. Parking in front of
the construction area has
been suspended to ac-
commodate heavy machinery and equipment that will soon
be arriving. Administration asks that you please comply with
the no parking restriction for this area and there is plenty of
parking around the Center. Questions concerning parking
may be directed to Facilities Operations, ext. 1328.


Syvertsen Research Visit to Spain


D r. Jim Syvertsen was on a 2 month research
visit to southern Spain during October and
November 2005. Ex- c penses were funded by a grant
from the Seneca Foun- nation who fund agricultural
research projects in the Murcia region. The research
project was in collabo- ration with Dr. Paco Garcia-
Sanchez, former post- doc in Dr. Syvertsen's lab,
and Dr V. Martinez of the Plant Nutrition group in
CEBAS-CSIC on the campus of the University of
Murcia. The research project dealt with salinity tol-
erance mechanisms in citrus rootstocks and focused
on interactions between salinity and potassium uptake
in unique solution culture facilities. Dr. Syvertsen was accompanied by his wife Jan, who soon got into daily
shopping for beautiful produce and seafood making it difficult not to eat too much healthy Spanish cuisine.
No doubt Jan would be willing to share some of those wonderful recipes with the rest of CREC.







Seminar Announcement

James W. Harris, Ph.D. Chief Scientific
Officer Bioavailability Systems, LLC, will
present a seminar entitled "Oral Bioavailability:
One of Pharma's Last Great Unsolved Mysteries"
at 11 AM Thursday February 23, 2005 in BHG 4.
Refreshments will be served at 10:45 AM.
The outline of his talk is as follows:

1. pharma productivity is a disaster; oral bioavail-
ability and variability thereof are prominent
causes of low productivity
2. brief disclosure of how we are working to improve
productivity
3. Spiro Ortho Esters can be removed from juice
4. audience questions

His seminar will explain the cause of the grape-
fruit juice-drug interaction (coumarin spiro ortho
esters) and how these compounds can reduce the
amount of certain ingested medications to achieve
similar blood concentrations.


rew Flynn (son of Karla Flynn, Word Process-
ing) was inducted into the National Junior
Honor Society at Grace Lutheran School on Wednes-
day, February 8. The president of the Chapter said 57%
of the 7th graders were inducted. This was the largest
group of students being inducted in the history of the
Chapter. After the induction ceremony, refreshments
were served in the fellowship hall. Congratulations
Drew!!
