Biomass may become an important source of combustible fuel in the future. For biomass, such as switchgrass, to be economically viable as a fuel, the processes required to take the plant material from a green, growing plant in the field to an energy dense package must be efficient. A self-propelled bale picking truck simplifies and speeds bale collecting, stacking, and staging for loading onto a truck for transport over the road.

Transgenic plants, plant material, and plant cells for synthesis of polyhydroxyalkanoates, preferably poly(3-hydroxybutyrate) (also referred to a as PHB) are provided. Preferred plants that can be genetically engineered to produce PHB include plants that do not normally produce storage products such as oils and carbohydrates, and plants that have a C4 NAD-malic enzyme photosynthetic pathway. Such plants also advantageously produce lignocellulosic biomass that can be converted into biofuels. An exemplary plant that can be genetically engineered to produce PHB and produce lignocellulosic biomass is switchgrass, Panicum virgatum L. A preferred cultivar of switchgrass is Alamo. Other suitable cultivars of switchgrass include but are not limited to Blackwell, Kanlow, Nebraska 28, Pathfinder, Cave-in-Rock, Shelter and Trailblazer.

The invention belongs to the technical field of ecological agriculture and particularly relates to a mixed seeding method for switchgrass and wild soybeans in saline-alkali land. The mixed seeding method is achieved through the following steps that firstly, after the saline-alkali land is ploughed and raked to be flat, mixed fertilizer composed of farmyard manure and erythromycin waste residues is applied to the saline-alkali land, and ridging is performed; secondly, switchgrass seeds and wild soybean seeds are placed in a seed processing agent in advance to be soaked for 8-10 min, hole sowing is performed on ridges, the wild soybean seeds are sown first, the switchgrass seeds are sown after soil covering, and soil covering and filling are performed so that the saline-alkali land can be flat; thirdly, normal field management is performed after sowing. According to the method, the switchgrass seeds and the wild soybean seeds are wrapped through the seed processing agent so that the seeds can be prevented from being eroded; meanwhile, germination of the seeds is accelerated, the germination rate and the germination potential are increased, the seeds are good in quality, operation is easy and fast, a large amount of manpower and a larger number of material resources are saved, the two crops cooperate with each other, growth is mutually promoted, stability is good, and high-quality forage grass is provided for development of animal husbandry in China.

The invention provides cat litter products and comprises the manufacture of a granulated panicum virgatum component which is mainly mixed with a granulated biochar component. Each component is granulated via an extrusion technique to form particles of about 40 microns. The combination of panicum virgatum and biochar granulated sand products together provides non-toxic and naturally safe, biodegradable, deodorant, and scented antibacterial sands; and the antibacterial sands are convenient for handling of convenient size agglomeration, have very little dust, and reduce track of cats.

Novel strains of Pseudomonas fluorescens are disclosed. Several novel mutated strains of Pseudomonads are engineered by repetitive culturing of a parent strain under stressed conditions. Various enriched populations are screened and ranked based on relative performance indices including viable cell yield during growth, efficacy in suppression of dry rot disease, cell growth recovery after dry storage and resistance to switchgrass hydrolysate.
