Nutriad announces new Asian partnerships
Energy from salmon sperm?
see much synergy with this association, with the depth of reach, from small to major customers that this partnership will bring.” In the Philippines Nutriad agreed for Enovet to be the sole importer and distributor of all major product lines. Stated BK Chew: “The partnership is very timely as the market has already recognized the need to move from AGPs on which NUTRIAD products will be a perfect fit.” Er ik Visser, CEO Nutriad: “Our new par tner ships allow Nutriad to get even more involved in the key feed markets in Erik Visser Boon Kee Chew Thailand and the In Thailand Nutriad appointed Philippines. Nutriad’s local sales Brenntag as its distributor. BK Chew, management, regional technical Regional Director APAC, high- management and global product lighted: “We are confident that the management will suppor t our Nutriad - Brenntag partnership will experienced distribution partners bring enormous benefits to both to establish product leadership in companies and our customers. We the market.” t the recent VIV Asia in Bangkok, Nutriad CEO Erik Visser formally announced new distribution par tnerships in Thailand and the Philippines: “Asia Pacific is an important region for our company…. In the coming years we aim to double our presence in this dynamic market and are therefore extremely pleased to partner with recognized companies that share our ambitions.”
New edition of AMINONews® by Evonik is out now
hreonine, an essential amino acid, is not only a building block in meat production but has also a key function in the metabolism of the intestine and in immune responses. The current knowledge about this subject and the consequences for an ideal amino acid profile of pigfeed is explained by Dr John Htoo in the latest edition of Evonik’s customer magazine AMINONews® for the feed industry. Amino acid supplementation is also catching on in aquaculture. But how to define a species’ amino acid requirements? Dr Andreas Lemme provides an insight into test approaches for tilapia feeding. As the results show, the optimum methionine concentration for this African cichlid fish is significantly above current recommendations. New approaches to animal nutrition also come along with new findings on the topic of oxidative stress. Dr Behnam Saremi summarises the basic mechanisms for the latest AMINONews®.
Evonik is the only company in the wor ld that produces and mar kets all four essential amino acids used in advanced animal nutrition: MetAMINO ® (DL-methionine), Biolys® (L-lysine source), ThreAMINO® (L-threonine) and TrypAMINO®
(L-tryptophan). Mepron®, a rumenstable DL-methionine for highperformance dair y cows, and CreAMINO®, a creatine source for broilers complement the product portfolio. The company markets innovative products and services in more than one hundred countries and thus makes a valuable contribution to the cost-efficiency of its customers and to healthy and environment-friendly animal nutrition.

n aquaculture, we are looking at issues of functionality and sustainability in order to produce more fish at affordable prices to feed the World. But there are some other applications that are promising and fascinating. For example, have you ever thought how fish and batteries are connected? A research group in China have turned to nature to help overcome one of the key challenges facing the most probable successor to the lithium ion (Li-ion) battery by using salmon sperm! Today, lithium–sulphur (Li–S) batteries are cheaper, more sustainable and already capable of delivering up to three times the energy density of most Li-ion cells. However, they are not stable and this is a major problem for further development. Li–S cells typically consist of a lithium metal anode and a carbon–sulphur cathode separated by a liquid electrolyte. Lithium ions dissolve from the anode during discharge, reacting with sulphur to form lithium polysulfides (Li2Sx) at the cathode, while the reverse occurs on charging. Some of the polysulfide intermediates are unfortunately soluble in the electrolyte and their dissolution from the cathode leads to irreversible loss of the active sulphur, adversely affecting cell performance. Several strategies have been tested to reduce the Li2Sx dissolution problem, which often involve coating the cathode to isolate sulphur from the electrolyte, or hybridising it with third party materials that can help to anchor Li2Sx to the cathode surface through electrostatic interaction with the lithium ions. The drawback with these approaches is that there is substitution of the active materials that can increase internal resistance or reduce capacity. In a important development, though, Chenggang Zhou and his colleagues at the China University of Geosciences, Wuhan, have been looking for an additive that was molecularly lightweight, dispersible on the carbon–sulphur cathode material, and rich in sulphur-loving functional groups, they thought of DNA. Computational chemistry verified that functional groups common in all four of the nucleobases that comprise DNA were sulphur-loving, with phosphate groups exhibiting the strongest adsorption. Having confirmed their suspicion, the team then observed experimentally a three-fold enhancement in capacity retention after 200 discharge cycles by dispersing a small amount of DNA derived from salmon sperm onto the carbon–sulphur surface. This development is quite exciting in terms of crossing species barriers but also on joining forces of material scientists with bioscientists. The future is definitely holistic and “salmony”!
