Reserved parking in basement, 467-6996 UNL professor discoversfood preserver Experimental slip harvests usable bacterial toxins By Tony Gardner Staff Reporter The discovery of a new, organic way to keep food safe, well-preserved and fresh was recently stumbled upon in a UNL experiment that went wrong. A team led by Bob Hutkins, a University of Nebraska-Lincoln pro fessor of microbiology, was working ,on an experiment that would allow them to ferment meat. However, they ended up with a discovery that aids in food preservation. The process utilizes the ability of a certain bacteria to produce natural defenses that impede other bacteria, which in this case causes food to spoil. While the technology is old, the pro cess has been used in food only re cently, Hutkins said. The process takes advantage of toxins called bacteriocins that are cre ated by a producer bacteria normally used to make fermented foods. The toxins are used to target bacteria that are hazardous to humans and kill off the pathogenic bacteria that cause food poisoning and other disease-caus ing bacteria. “It was just a matter of finding the right bacteria to kill off the disease -44 The simple declaration *no artificial preservatives* provides some marketing advantages. —Hutkins professor of microbiology ---99 - causing bacteria,” Hutkins said. The process was discovered when the first project the group undertook was thought to have failed. The initial project was to use the producer bacteria to ferment a sum mer sausage. The fermentation did not occur, but researchers found that while the producer bacteria did not grow, it produced enough toxins to kill off the pathogenic bacteria. Researchers realized that the dis covery could be used in food where fermentation was not wanted. The process is safe, Hutkins said, and has already been used in foods. The goal of the product is to im prove the shelf life and safety of many kinds of foods and to back up existing safeguards. k SUNDAYS ^V.

Last year, 500 Jonors attended the drive. “Every year, we get more people,” she said. “It’s becoming more well known.” The entire blood-giving procedure takes about an hour, she said. The first step in giving blood. Gray said, is a testing procedure in which nurses test blood for iron content and antibiotics and ask donors about their medical history. The test takes 15-20 minutes. The actual drawing of the blood takes only about 10 minutes. After giving blood, donors are escorted to tables where they can sit down, eat doughnuts and drink orange juice. Red Cross personnel recommend students rest at least 10 to 20 minutes after giving blood. Gray said an ample blood supply was important for medical emergencies. “There are important benefits that people in emergency wards get,” she said. “It’s unbelievable. They save lives.” There is no risk of disease from giving blood, Gray said. % “You can’t get AIDS or hepatitis from donating blood.” CAPS Continued from Page 1 Previously at the Mental Health Apartment, students paid $10 for heir first session and received their second through fifth sessions free, he said. After the fifth session, the cost etumed to $10. Now, the first three sessions at HAPS are free to all UNL students, he aid, whether or not they pay student ees. Sessions four through 24 cost $10 f the student has paid student fees, tartnoy said. Otherwise, students must My non-subsidized fees. However, with non-subsidized fees it about $65 to $70, Portnoy said student fees paid for themselves in ibout two visits. After the 24th session, each session :osts $30, to recognize that services ire long-term and can prevent other students from accessing services, 5ortnoy said.

Portnoy said many universities allowed students only four to six visits, then referred them to private practitioners. UNL’s system allows for more flexibility, he said, because employees can work with students as long as they need help. However, many students who come to CAPS can work out their problems in one or two sessions, Portnoy said. He emphasized that CAPS was not just for students with serious problems. A stigma can be attached to seeking psychological help at the Health Center, he said. Sometimes people think the Health Center is more medically oriented, meaning people must be mentally ill to receive help there. “That’s not even close to the reality,” he said. Portnoy said staff members wanted everyone on campus to feel comfortable coming to CAPS. One way CAPS tries to do this is by not having students working in the POLICE REPORT Beginning midnight Friday. 12:39 a.m. — Gate arm stolen, parking lot at health center, $25. 1:20 a.m. — Plants stolen, Theta Chi fraternity, 626 N. 16th Sl, . $170. 3:24 a.m. — Person driving while intoxicated, 17th and Vine streets, one person taken to Lancaster County Ail. 3:26 a.m. — Accident, 15th and S streets, $3,500. , 4:03 a.m. — Window damaged, Lambda Chi Alpha fraternity, 1345 R St., $10. 11:10a.m.—Stolen jacket recov ered, Bob Dcvancy Sports Center. office, he said. Portnoy said he was concerned that students might feel their confidentiality was somehow compromised if other students worked in the office. Keeping student workers out of the office is a tradition of the Mental Health Department, but not the Counseling Center, he said. In effort to make everyone feel welcomeatCAPS, Portnoy saidCAPS also had been working with groups such as the Women’s Center and Multi-Cultural Affairs. He also said the staff was made up of diverse races, backgrounds and, sexual orientations. - - -- Given the circumstances of the budget crunch, Portnoy said he thought the transition had gone smoothly. “I like to think that we’ve been able to blend these two traditions into a very positive department... and in the process reach more students than we ever did in the past,” Portnoy said. 1:11 p.m. — Accident, south of Temple Building, $300. 10:35 p.m. — Woman hit by un known object, Devaney Sports Center. 11:06 pjn. —- Wallet stolen, Vet erinary Basic Science Building, $20.
