In Jan. 2015, Shineking Biological
planned to build a polyamino acid project, as polylysine boasts great
potentials in the application of food preservative. And polyglutamic acid
presents a bright future to perform as fertilizer synergist.

In Jan. 2015, Nanjing Environmental
Protection Bureau announced that Nanjing Shineking Biological Technology Co.,
Ltd. (Shineking Biological) planned to build a polyamino acid project with the
investment of USD16.34 mllion (RMB100 million). Located in Nanjing Biotech and
Pharmaceutical Valley, the project includes 500 t/a polyglutamic acid, 20 t/a
polylysine and 100 t/a chrial amino acid. The project is undergoing
environmental impact assessment.
Mr. Feng, manager of Shineking Biological,
disclosed that polyglutamic acid can be performed as fertilizer synergist. For
one thing, synergist fertilizers that use polyglutamic acid could improve the
output of crops. The average fertilizer utilization will improve 7%-12% by
adding polyamino acid synergists. In detail, the average output of grain crops
and industrial crops will increase 15%-25%, root and tuber crops can even get a
30% increase. With the crop yield increase, farmers can get an income of USD16.34
(RMB 100) per mu and the figure would be USD490 (RMB3,000) if they plant
industrial crops. For another, polyglutamic acid synergist fertilizer will help
agriculture to develop in a more environmental friendly way. If 20% of the
original fertilizers could be replaced by polyglutamic acid synergist
fertilizers, then 2 million tonnes of fertilizers could be saved every year, to
the equivalent of reducing 4 large scale chemical fertilizer plants.
For a long time, farmers used a lot of
fertilizers in planting crops in order to get a harvest on account of the large
population but small land in China. Data showed that the cultivated area in
China is less than 10% of that in the world, while 40% of fertilizers were used
in China. Besides, the utilization ratio of traditional fertilizers in China is
low, together with the over use of chemical fertilizers, making the soil
becoming hard and water eutrophication becoming even serious. As a result, soil
quality is deteriorating.
At present, the polyamino acid fertilizer
technology had achieved industrialization in China. The leading polyamino acid
urea manufacturer is Luxi Chemical Group Co., Ltd. and the leading polyamino
acid compound fertilizer manufacturers are Shandong Sunfull Chemical Co., Ltd.
and Hubei Xiangyun (Group) Chemical Co., Ltd. As for polyamino acid soluble
fertilizer, Xinjiang Huier Agriculture Technology Co., Ltd. is leading the way.
Except for performing as fertilizer synergists, polyglutamic acid can also be
widely used in fine chemical, medical and water treatment industry.
It is noted that ε-polylysine can be served
as a green nutritional food preservative, which was approved by the National
Health and Family Planning Commission of the People's Republic of China in
April 2014. Ε-polylysine will replace chemical preservatives to become the
major fresh-keeping material. Besides, it will also used in drug carrier and
sanitizer industry.
Founded in 2010, Shineking Biological is
specialized in the production of biopolymers through the method of microbiological
fermentation. Its major products are γ-polyglutamic acid, ε-polylysine,
isomaltulose and tagatose. After launching the Standard for Polyglutamic Acid
Enterprise in China for the first time, Shineking Biological becomes the leader
in drafting the cosmetic-grade and agricultural-grade polyglutamic acid
industrial standard.
